IP-video security and surveillance for a city road-works department.
The problem: preventing theft
A city road-works department in Germany is responsible for installing and maintaining traffic lights and street lights. The department houses its raw materials, including lampposts and cable reels, in an outdoor area on its premises. Until a few years ago, there was never any problem with the outdoor storage area. But, as metal prices rose, the department found itself the victim of metal theft, not once, but multiple times. Lockers and barriers set up to protect the materials proved to be an unsuccessful solution as the thieves were quite professional. The city needed a better solution to secure its outdoor storage area.
An IP video network
To improve security, the department turned to Black Box for an IP-video surveillance system.
The first step was to perform an on-site survey to determine the best locations for the security cameras. The next step involved the implementation of the IP infrastructure. The plan called for three distributed camera locations, each equipped with an Ethernet switch connecting the IP cameras. For convenience, it was decided to use a PoE switch to power the cameras over the Ethernet lines instead of running separate power lines. In addition, each camera location was furnished with a wireless Ethernet extender providing a remote, wireless connection to the city’s central LAN. Black Box delivered the wireless Ethernet radios fully pre-configured for an easy plug-and-play installation by the customer. Because both the switches and extenders are being used outdoors, they are designed with IP-rated cases and are capable of withstanding extreme temperatures.
A legal regulation demands that the system have the capability to be shut down on demand. To meet this requirement, Black Box provided on-site training to instruct the security team how to control the cameras over the web interface on the Ethernet switch. The operation is quite easy and the team understood quickly how to switch cameras on and off and how to change the viewing angle. Monitoring the video the IT team still needed a solution for displaying the video from the surveillance cameras. Black Box suggested and installed a 2×2 video wall with four HD screens at the gatehouse for 24/7 monitoring.
Because the customer had experienced theft, everyone was worried about the security of computers in the gatehouse. Black Box suggested that the customer back-rack these computers to a secure location inside the main building. The advice was highly appreciated and the customer moved the computers to a secure location and connected them to the gatehouse using a KVM extender.

Machine vision technology—the image-based automatic inspection process—has matured greatly and is now becoming an indispensable tool in manufacturing to increase quality and profitability. USB 3.0, with its 5-Gbps throughput and ability to send power and data over the same line, has greatly contributed to this growth.
What is machine vision?
Machine vision is an image-based, automatic inspection and analysis system for applications, such as process control. It automatically takes pictures to inspect materials as they come down the assembly line.
Other machine vision applications include:
Medical vial inspection.
Robot guidance and orientation of components.
Engine parts inspection.
Machine vision uses a small industrial camera and lights mounted near an assembly line to take pictures of product as it passes. The images are then analysed by software to determine if various aspects of the product meet acceptable specifications. For instance, if a label is misplaced, the bottle will be rejected. All of this is done at incredibly high speeds—fractions of a second.
Years ago, machine vision systems were very expensive, costing hundreds of thousands of dollars. But in the last 15 years or so, advances in technology have brought the cost of machine vision down, making it a practical solution for 100 percent quality control. And the cost for implementing machine vision keeps decreasing as technological capabilities increase.
Machine vision is now an indispensable tool for quality assurance, sorting, and material handling in every industry, including electronics, food processing, pharmaceuticals, packaging, automotive, etc. It is an economical way to make sure sub-spec product is rejected. Machine vision can be used to inspect for geometry, placement, packaging, labeling, seal integrity, finish, color, pattern, bar code, and almost any other parameter you can think of.
USB 3.0 and machine vision
USB 3.0 brings a number of advantages to machine vision systems. Because of its 5-Gbps throughput, ten times more than USB 2.0, it eliminates problems of stability and low latency for image transmission and camera control. USB 3.0 enables the transmission of higher-resolution, higher-frame rate video with no loss of quality.
USB 3.0 also sends data and power on the same line. This is enough to power a camera without worrying about a separate power supply or power line.
In addition, compared to older systems, USB 3.0 is plug-and-play, making it easy to swap out cameras and other hardware, such as USB 3.0 extenders, and other devices.
KVM matrix switching gives multiple users access to a variety of target devices, including but not limited to CPUs, digital signage, and servers; the ability to monitor workflow; and flexible control of visual and peripheral elements.
Deploying KVM extension that operates over a LAN/WAN (local area network/wide area network) and incorporates virtual and physical CPUs gives retailers access options, reduces clutter in the workplace, and saves on energy costs.
In retail and inventory management systems virtualized remote computing is especially advantageous. Receiver units at the cash registers can access information on a virtual machine that runs on a server appliance.
This remote virtual system gives users access to their Active Directory accounts that is incorporated into a connection broker, with no need to set up a separate directory on the KVM system. The receivers gain access to virtual machines via Microsoft® Server 2008 or Microsoft Server 2012. By utilizing a connection broker, the virtualized machines can be easily duplicated, enabling workers to connect to the first available target without having to identify the target. This streamlines workflow and simplifies processes in busy retail applications.
In addition, a KVM system that works over a LAN/WAN this way supports NLA (network level authentication) for security. It also can continue to support physical CPUs while expanding into virtualization.
As is seen in KVM technology, other benefits include a low total cost of ownership (TCO); improved operability and quick ROI; maximum, scalability, and improved reliability; and green IT solutions with energy-saving design and distribution.

Of all the components in your network, none is arguably more underrated than the RJ-45 connector. Simplicity incarnate, this transparent marvel literally defines plug-and-play connectivity—from the desktop to the data center. Yet it defies the obvious: How’d they get those wires in there? Who puts these things together? Where are the seams?
So, in the spirit of demystifying one more aspect of modern-day communications, we give you this behind-the-scenes look at terminating twisted-pair cable using RJ connectors.
The prep work.
First, gather your materials. You’ll need bulk cable, such as the bulk cable, a cable cutter and stripper, a connector, a pre-plug (optional), a crimp tool, and a continuity tester. All these items—except the cable and the pre-plugs—are in our CAT6 and CAT5e Terminations Kit.
The challenge: Do it right the first time.
You must take time to install each connector carefully, according to the specifications of the wiring system you’re installing. Then test each cable to certify that it supports the specified performance levels — in this case, the TIA specs for CATx cabling. The wiring standards illustration (above right) indicates proper T568A, T568B, and USOC pairing and pinning for twisted pair cable. T568B wiring is most commonly used in Europe for networking.
First, start with a wire stripping tool, such as the Multi-Strip (FT231A). Next, put the tool around the cable, squeeze, and carefully remove the jacketing from the cable. You’ll want to expose about one inch of the insulated wire conductors.
DO NOT remove any insulation from the conductors.
When you crimp the RJ-45 connector, the contacts inside will pierce the conductor insulation to make contact, so there’s no need to do it here.
Untwist each pair of conductors to within 1⁄8″ of the jacket with a stripping tool. Do not untwist the conductors more than 1⁄2″. Arrange the wires according to the cable spec you’re using (T568B in this case). Flatten and align the wires. Use your wire cutters and make one straight cut across all the conductors. Trim the ends to ensure they’re all of equal length. Once you cut the cable, make sure you flatten out the wires.
Orient the wires so the cable’s Pin 1 connector aligns correctly with the RJ-45 connector’s Pin 1, and do the same for all pins. (To maintain the correct alignment, see “Rule of Thumb” below.) While carefully maintaining the proper position of each conductor, slide the wires into an RJ-45 connector.
All connectors must extend all the way into the conductor so they’re flush against the back and aligned underneath the contacts within the plastic connector housing. The cable jacket should also extend into the connector about 1⁄4″ for strain relief.
Rule of Thumb:
Many people miswire RJ-45 connectors because they’re careless about proper conductor alignment. Before terminating connectors, be sure they’re oriented properly so connector Pin 1 aligns with cable Pin 1, etc. To determine which RJ-45 contact is Pin 1 in CATx applications, hold the connector in front of your face as if you were going to plug it onto the tip of your nose. With the locking thumb tab up, connector Pin 1 is on the far left.
Insert the connector into an RJ-45 crimp tool. Make sure you’re using the proper die for the type of connector you’re using. For instance, connectors that use a load bar require a different crimp die than connectors that don‘t feature a load bar. If you don’t use the right die, you’ll damage the connector when you try to crimp it.
Firmly squeeze the crimp tool handles together. They’ll lock in a ratcheting action as you crimp the connector. A final click indicates the connector is firmly latched, and you can release the handles.
Check your work using a continuity tester or cable certifier rated for the cable standard you’re installing. Your tester should be able to check for shorts, opens, or miswires.
For network certification, more expensive testers can even store and download test results based on standardized minimum performance levels.
The majority of RJ-45 cables are terminated by machine. But field technicians and professional cable installers crimp on modular connectors every day. You can terminate cables, too. Once you do, you’ll gain a new appreciation for the skill it takes to successfully terminate these cables inside a connector the size of a jelly bean.
Research shows collaborative environments foster innovation, improve team performance by ensuring everyone is working towards the same goal, and increase employee retention since people prefer to belong to a team and contribute to the team’s goals. Next generation workers and the need for companies to compete on a global basis will drive demand for collaboration solutions throughout the organization, according to a Wainhouse Research study.
Perhaps that’s why, in recent years, a more agile approach to meetings and working in collaborative groups has been embraced by schools and businesses of all sizes. Implementing collaboration solutions such as huddle spaces, or small-space meeting areas, in addition to larger conference rooms is one of the ways organizations are making this change.
What is a huddle space?
A huddle space is a smaller meeting space, which can take place just about anywhere. It typically accommodates six or less attendees. They range from basic spaces to well-equipped and advanced rooms. Basic huddle spaces, with either open area or private closed rooms, may be equipped with a small table, some chairs, a speakerphone, and perhaps a dry erase board. Whereas, well-equipped and advanced huddle rooms may include flat panel displays, integrated AV conferencing, and a wireless presentation system. Huddle spaces do not typically include enhancements such as ceiling speakers, acoustic wall treatment, or AV control system.
What should your huddle space include to promote collaboration?
The way huddle spaces are used varies by organization, location, vertical market, culture, etc. Whether or not a huddle space is effective depends on the given task and requirement of the space. If you’re planning for a well-equipped huddle space, you should also consider your AV technology needs as well.
In general, your huddle space should include equipment that has:
Interoperability with other products you may have in the space such as screens, projectors, panels, or touchscreens.
BYOD support which allows collaboration/sharing of any type of device the meeting participant has. For example, participants could bring a laptop, tablet PC, mobile phone, or netbook and connect with ease.
Content sharing capabilities. For example, a presenter may need to share any number of pieces of content with other participants simultaneously.
An intuitive interface, which will reduce barriers to use. The easier your equipment is to use, the more participants feel comfortable using new technology.
The ability to allow an unlimited number of users to participate. While there is a practical limit to the number of people that can fit in a room or share a screen, facilities change and so do user’s needs. Try not to get locked into limiting systems which only allow 4-6 concurrent users.
In addition to many of the items needed to make a good huddle space, for your larger conference rooms you may need additional AV solutions.
What should your modern conference room include to promote collaboration?
Today’s larger meeting rooms often come with higher expectations. They will certainly start with the same type of collaboration solutions discussed earlier for huddle spaces. Additionally, they must provide support for tomorrow’s technology using today’s design. These rooms often require more types of equipment, which may require support for a wide range of video signals.
In general, your modern conference room should include equipment that has:
Switching capabilities to manage video signals that need to be shown on one or more displays.
Presenter control options for switching. For more efficient meetings, select a switch that automatically switches to a new source when a new user connects a device.
Scaling able to work with a wide range of video signals, both current and legacy, to ensure the display is compatible with anything that needs to be presented.
Reliable video distribution capabilities to send and receive audio, video, control and even power from another room or building.
Video wall capability to display any source from anywhere with switching control.
When designing and outfitting the spaces, it’s important to think ahead and design for AV systems that can adapt and grow as technology changes.
Recall we started with the MediaCento IPX PoE Multicast 1 x 4 Kit. The kit includes a transmitter, four receivers, a PoE (Power over Ethernet) network switch, and five 2-meter (6.5-feet) locking HDMI cables. Everything you need to multicast HDMI video over an IP network and create static video walls.
In order to make the video wall dynamic, you’ll need to add to the existing system:
Another source (e.g., digital signage player, PC, laptop, Blu-ray player, DVD player, etc.)
The additional sources and transmitters enable additional content to display, and the controller enables you to take full control over the IP-based transmitters and receivers.
Let’s dive right in to the MediaCento multicasting system and get the controller up and running.
Step 1: Connect Additional Transmitters to the Switch and Source
In this scenario, we have one additional source, a laptop, so we will need one additional transmitter. Connect the second transmitter to the PoE network switch using a CATx cable. Then, using a locking HDMI cable, connect source – in this case, a laptop – to the transmitter unit.
Step 2: Connect the MediaCento IPX Controller
Connect the power supply to the controller and connect it to the network switch using a CATx cable.
Step 3: Access the Controller’s Web Interface
Use the Web interface to configure the controller. Open the Web browser, and type the IP address in the address field.
Note: For more details regarding IP addresses, see the user manual included with the controller.
Step 4: Detect Units
In the Web interface, go to the Hardware tab and:
Click the “Detect Units” button. The controller automatically detects all receivers and transmitters on the network. In this case, the IP address of the transmitter connected to the laptop is 169.254.4.73 and the iCOMPEL media player is 169.254.2.58.
Optionally, rename the receivers for easier setup. Click the “Show OSD” button to show the receiver’s IP names on the displays, and then click the “Rename Device” button to rename each of the receiver’s IP addresses to a findable name. For example, C1 R1 (for column 1, row 1), C1 R2, C2 R1, and C2 R2.
Step 5: Update Group Settings
In the Web interface, go to the Groups tab and:
Name this group to “2×2 Video Wall” in the Title field.
In the “Receivers not in Group” list, select the receivers that you want displayed in the video wall and click the > button to add them to the “Receivers in Group” list. The receivers will appear below the lists.
Check the Video Wall This will open the video wall settings where you can specify the number or rows and columns in the video wall as well as monitor information (i.e., bezel width and monitor height and width). It also displays a video wall table.
Enter 2 for the number of rows, and 2 for the number of columns. The table will change to show a 2×2 video wall table.
Drag and drop the receivers where you would like them displayed in the video wall table. (This is where having the receivers renamed to something more meaningful helps with setup.)
Click the “Save Group” button.
Step 6: Enable Full-Screen Video Wall
Still in the Web interface, go to the Custom Display tab and select which source you would like to connect to the grouping that was just created. To switch the iCOMPEL media player to show the video wall across all the screens, click the box in the 169.254.2.58 (the IP address associated with the transmitter connected to the media player) column, 2×2 Video Wall row. Then, click the “Switch” button.
Step 7: Switch Content to Dynamic Display
To switch the display from the video wall only to show the source from the laptop in column 1, row 1, click the box in the column with the second transmitter, 169.254.4.73, and click the “Switch” button.
The screen will change to show the content from the second source. In this case, it is pulling content from a Web page.
Still in the Custom Display tab, click the “Save as a New Preset” button to make the configuration available in your dashboard. The dashboard is available on the mobile application; therefore, with the preset defined you can switch and control the displays from your mobile device.
That’s it! In just seven steps we took the static 2×2 video wall and made it dynamic with switching and control. This is just a snippet of the system’s capabilities. The system can create up to 8×8 video walls with 64 screens.
PoE is a technology that works well for wireless access points, video surveillance, building management, retail video kiosks, smart signs, and retail point-of-information systems, making it possible to easily move a device with minimal disruption. Additionally, if your LAN is protected from owner failure by a UPS, the PoE devices connected to your LAN are also protected from power failure.
Using Power over Ethernet can save hundreds of dollars per Wi-Fi access point (AP) locations compared to a non-PoE solution.
In a non-PoE installation, in addition to the Ethernet backhaul link, power must be wired to the access point. Depending on factors such as AP location, distance from the AC circuit, and local safety codes, the savings from using a PoE solution can be $250-$500 per AP. In harsh, outdoor, or industrial environments, you can save $750-$1500 per AP by using Power over Ethernet.
PoE Mid-Span Injectors add power to Ethernet for powering PoE powered devices ranging from wireless access points to IP cameras. PoE enables you to easily move equipment from room to room without costly, time-consuming rewiring.
Power over Ethernet is also the answer if you’re doing a high-density phone conversion from keyed phones to VoIP phones. There’s a much lower installation cost—all you need to do is provide the Ethernet connection. We have a variety of PoE PSE equipment including switches,media converters, and injectors.
Plus, using PoE can improve VoIP phone system availability. Power over Ethernet PSE gear can be located in data centers with uninterruptible power supplies and battery backup. This arrangement means that your PD VoIP phones will remain working if there’s a power failure. On the other hand, wall-powered phones will stop working when the power goes out.
Industrial connectivity and KVM control room solutions for upstream, midstream, and downstream environments.
As the oil and gas industry continues to grow, more and more well sites, pumping stations, pipelines, processing plants, and refineries are being built. Along the entire route, safe, reliable networking and industrial automation are critical to smooth operations, efficiency, and productivity.
In 2014, the United States produced 9.2 million barrels of crude oil a day. The U.S. is now the largest producer of oil and gas, overtaking Saudi Arabia and Russia due to production from the Marcellus Shale. However, reservoirs of oil are becoming more difficult to access and increasingly less productive. To keep pace global consumptions, oil companies must constantly look for new sources of petroleum, as well as improve the production of existing wells.

The sheer number and different types of cabinets and racks can make choosing the right one for your data centre a daunting task. But, if you consider your requirements one at a time, you can zero in on the right cabinet or rack for your application.
A cabinet is an enclosure with four rails and a door (or doors) and side panels. A rack is an open, freestanding 2- or 4-post frame that doesn’t have doors or sides. The decision on whether to use a cabinet or rack depends on a number of factors.
Before you choose a cabinet or rack, you need to determine what equipment you’re planning to house. This list can include servers, switches, routers, and UPSs. Consider the weight of your equipment as well. The extra stability of a cabinet might be important if you’re installing large, heavy equipment like servers. An open rack is more convenient than a cabinet if you need frequent access to all sides of the equipment.
With the open design, racks are a good choice in areas where security isn’t a concern such as in locked data centres and closets. And racks typically cost less than cabinets.
Cabinets, on the other hand, protect equipment in open, dusty, and industrial environments. Aesthetics can be a factor too. Will customers or clients see your installation? A cabinet with a door looks much neater than an open rack. When you’re trying to create a professional image, everything counts.
If your equipment needs ventilation, a rack offers more air circulation than a cabinet. Even if your cabinet is in a climate-controlled room, the equipment in it can generate a lot of heat. The requirements for additional airflow increase as more servers are mounted in a cabinet. Options to improve airflow include doors, fans, and air conditioners.
Width: The width between the rails in both cabinets and racks is 19 inches with hole-to-hole centers measuring 18.3 inches. But there are also cabinets and racks with 23-inch rails. Most rackmount equipment is made to fit 19-inch rails but can be adapted to fit wider rails.
Rack Units: One rack unit (RU or U) equals 4.45 cm (1.75 inches) of vertical space on the rails. A device that’s 2U high takes up 8.89 cm (3.5 inches) of vertical rack space. Rack units are typically marked on the rails. The number of rack units determines how much equipment you can install.
Depth: Cabinets and four-post open racks come in different depths ranging anywhere from 61 cm to 122 cm (24 to 48 inches) to accommodate equipment of varying sizes, particularly extra-deep servers. The rails on some cabinets and 4-post open racks are also adjustable to different depths.
When you consider the width, height, and depth of a cabinet or rack, clarify whether they are inside or outside dimensions.
Cabinets and racks vary in terms of the amount of weight capacity. Some cabinets can hold 500 kg or more. Carefully consider the weight of your equipment and decide where you want to mount it before choosing a cabinet or rack.
The vertical rails in cabinets and racks have holes for mounting equipment. Two-post racks typically have threaded 12-24 or 10-32 tapped holes. Four-post racks and cabinets often have M6 square holes for mounting servers.
7. Moisture, dust, shock, vibration
When housing electronic components outside of a protected data centre, look for a cabinet with an IP rating. IP standards are designed for corrosion resistance, protection from rain, submersion, liquids, dust, falling objects, and other hazards. Cabinets and racks can also be bolted to the floor for extra stability.
8. Power provisioning
There are multiple options for powering rackmounted equipment. Power strips can be mounted vertically or horizontally. Power Distribution Units (PDUs) and Power Managers have additional capabilities such as remote management and metering. Uninterruptible power supplies (UPSs) typically mount in the bottom of a cabinet or rack because of their weight.
9. Cable management
Most cabinets and racks have built-in cable management troughs and cable rings for routing cable. For a complete overview of our cable management solutions, visit our online store.
10. The extras
The type of shelving you choose depends on the equipment you plan to mount. There are multiple options: solid, vented, stationary, and pull-out shelves. And there are shelves built to hold specific pieces of equipment, such as servers or keyboards. Other extras include fans, waterfall brackets, and grounding bars.
Analog technology can’t keep up in the digital marketplace. Digital video is sharper and digital KVM is faster. Don’t get left behind in the digital revolution.
1. The VGA standard is being discontinued.
The VGA standard will not be supported going into 2015. Analog KVM and video won’t work any longer either. VGA sources and displays are getting increasingly difficult to find. We recently heard from a client who had to buy VGA parts on eBay.
2. Digital technology is distinctly better.
Digital technology improves users’ experiences by providing crystal-clear images at any supported distance. HD video is delivered pixel by pixel to digital displays at higher resolutions and increased color depth.
3. Digital systems are bigger and better.
New larger matrices and IP-based systems increase flexibility and enable connecting to a much higher number of endpoints. Thousands of devices can be incorporated into one unified system. On a digital matrix system, I/O ports are interchangeable, making changes and adds as simple as plugging a device into a port.
4. HD video switching is faster than it’s ever been.
Digital systems provide instantaneous HD video switching with no delay. Digital KVM switching is much faster, too, nearly instant rather than having to wait several seconds for video to show up.
5. Digital KVM improves the user experience.
Digital KVM systems feature improved USB support and compatibility with most other USB devices on the market: touchscreens, flash drives, tablet computers, as well as the workhorses, keyboards and mice.
6. Higher resolutions mean better images.
Increased bandwidth gives users the capability to work with images at higher detail levels as well as fit more content on the desktop for a more efficient workflow. Future-proof systems accommodate support for WQXGA (2560 x 1600) and 4K/UHD (3840 x 2160). Wherever users need pixel-perfect image transmission, they can now get it, via CATx or fiber cabling. Plus, send USB, serial, and digital audio signals.
AV Technology named the DCX3000 Matrix Digital KVM Switch from Black Box a Best of Show Winner at InfoComm 2015. This innovative product was demonstrated at the show, which took place in Orlando, FL, June 17–19.
Small size and big performance set the DCX3000 apart from other digital matrix switches in its class. Created for smaller organizations that need to upgrade to digital KVM signal switching and extension, the DCX3000 reaches 30 endpoints over CATx cable. Go up to 10 m from the workstation to the KVM switch and up to 50 m from the switch to the CPU.
The DCX3000 Matrix Digital KVM Switch features zero latency and zero compression of the signal transmission. The Graphical User Interface (GUI) is simplified for ease of use. In fact, according to the judges at AV Technology, this was an award-winning feature. “The unique thumbnail preview provides a simplified graphical user interface, making it easier to view multiple screens than text-based, on-screen menus,” according to one of the judges.
Digital KVM matrix switching gives multiple users access to the same systems in real time for monitoring and controlling processes. Learn more about migrating to digital KVM.

As the world’s largest appliance maker, Whirlpool Corporation knows a thing or two about innovations. But the company recently looked at its factories’ mixed networking devices and realised that their backend infrastructure needed some innovating too. An unstable wireless network set-up was costing the company money, was difficult to troubleshoot and simply could not keep up with new technologies.
Whirlpool turned to Cisco and the appliance company’s service provider, Black Box Network Services, to come up with a plan to update their network architecture.
Beginning with five pilot sites—including one of Whirlpool’s largest plants—Cisco employed designs to modernise the network. The products included in the plans were:
Cisco Catalyst 3750X switch
Cisco Catalyst 2960X Series switches
Cisco FlexStack and StackWise cabling
Cisco Aironet 3600 Series Access Point with Cisco CleanAir technology
Cisco 5500 Series wireless controller
Additionally, network traffic was collected and analysed by Cisco IOS Netflow, while Cisco Prime centrally managed the entire network.
Operations at the five test plants have soared as information now moves faster than ever. Networks are better equipped for video, which is speeding up innovation design and time to market. Issues can be dealt with quickly, before business can be impacted.
Whirlpool workers have been happy with the changes.
“Some engineers say they never realised how bad the old network was,” said Whirlpool program manager Greg Fisbeck. “Jobs that used to take a half an hour now take just a few minutes.”
Whirlpool was so pleased with the initiative in the five pilot plants that it will be upgrading their remaining 80 plants worldwide at a clip of 20 locations a year.

Here’s a checklist to use as you shop for a future-proof, high-performance digital KVM switch or switching and extension systems. It’s easy to remember as FAR-PARSS.
Any enterprise-wide KVM system should be flexible enough to input and output many types of video and peripherals, especially if you are in broadcast or command and control. Video signals such as DVI, HDMI, and VGA should be supported with resolutions ranging from 1080p to 4K. Other signal types to look for are audio, USB 1.1 or 2.0 for peripherals like keyboards and mice, and serial signals for industrial applications.
A flexible system should also be scalable for future growth. Calculate the total number of video sources and displays you have, and try to plan for growth. The KVM switches need to support current and future users with enough ports so that users do not have to create silos of servers and users. Look for a KVM system that can replace a video-only router with a high-performance digital KVM matrix switching system. A management controller enables central administration of the system. Does the management controller use a graphical user interface, or a text-based OSD?
When a KVM system can support video resolutions of 1920 x 1080 at 60 Hz or 3840 x 2160 at 60 Hz, test to make sure video does not lag or drop frames with rapidly changing content. Not all analog KVM systems or IP-based systems are up to the task, although most digital systems, including digital IP-based systems, can support fast, high-definition video.
Test keyboard and mouse setup to make sure there is no latency. A true USB emulation KVM switch is responsive and consistent; an unresponsive K/M jars the operator out of his/her workflow.
Optimally, a high-performance digital KVM system improves users’ productivity. In a matrix setting, all resources and displays can be connected and switched between by multiple users. Collaboration is enhanced by the ability to view and control the same resources simultaneously.
Calculate the longest distance between your endpoints, and make sure the KVM system can work over CATx or fiber cabling – or a mix of both – to reach all your targets. With digital matrix KVM systems, multiple users should have real-time access to targets.
New generation KVM systems will support redundancy options such as multiple power supply units for 24/7 uptime. Be sure to eliminate single points of failure. Make sure the system you select can support routing transmitters and receivers through two separate core KVM switches for full redundancy.
Many digital KVM switching systems support video-switching speeds of under a half second. Anything longer interrupts an operator’s workflow as he or she switches between resources and may be noticeable to a viewer. Does your KVM solution support custom keyboard shortcuts (also called hotkey shortcuts) that can be set for switching a local display as well as remote displays, such as other user terminals for collaboration or a video wall?
Lastly, KVM switching and extension systems need to be secure. Be sure administrators can assign specific access rights to specific resources. Remote configuration and maintenance of the KVM system enables an admin to securely log onto a system.
When you can mark off all eight of these categories, you’ll have maximized your ROI.
Fiber optic cable provides one of the most effective means today for safe, and long-distance communications, and it offers a number of advantages over copper. Fiber optic cable construction consists of a core, cladding, coating, strengthening fibers, and a cable jacket.
This is the physical medium that transports optical data signals from an attached light source to a receiving device. The core is a single continuous strand of extruded silica glass or plastic that’s measured in microns (µm) by the size of its outer diameter. The larger the core, the more light the cable can carry.
All fiber optic cable is sized according to its core’s outer diameter. The two most common multimode sizes are 50 and 62.5 microns. Single-mode cores are 8.5–9 microns.
The cores of OM1 and OM2 multimode cable are made differently than the cores of laser-optimized OM3 and OM4 cable. OM1 and OM2 have a small defect in the core called an index depression. This enables them to be used with LED light sources. OM3 and OM4 are manufactured without the center defect to enable them to be used directly with VCSELS for greater speeds and distance.
This is the thin layer that surrounds the fiber core and serves as a boundary that contains the light waves and causes the refraction, enabling light to travel the length of the fiber segment. Typical fiber cladding is 125 microns.
This is a layer of plastic that surrounds the core and cladding to reinforce and protect the fiber core. Coatings are measured in microns and can range from 250 to 900 microns.
These components help protect the core against crushing forces and excessive tension during installation. The materials can range from aramid yarn (Kevlar®) to wire strands to gel-filled sleeves.
Just like copper cable, fiber cable comes with PVC and Low Smoke Zero Halogen jackets. Whether you choose PVC- or Low Smoke Zero Halogen cable depends on where you are going to use the cable. PVC cable is typically used for patch connections in the data center, wiring closet, and at the desktop. Low Smoke Zero Halogen cable is used when you need to route a cable through the buildings air plenum. Low Smoke Zero Halogen cable has a flame-resistant jacket to inhibit the spread of fire.
