‘How to’ Guide for Specifying an IT Cabling System [Part 1] – Requirements and Preparation

Over a series of posts we offer guidelines on how to produce a specification for an IT cabling system that meets your organisation’s needs and gives you value for money.

Today we provide a checklist of the elements you should include and the information you should gather before starting work on the specification.

Requirements

Assuming you need a conventional structured cabling system using RJ45 connectors, the completed specification should include details on all or some of the following:

  • The Class or Category of cabling system e.g. Class D/Cat 5e, Class E/Cat 6 etc.
  • The number and locations of outlets
  • The location and type of telecommunications rooms and spaces
  • Backbone cabling between telecommunications rooms and spaces
  • Cabling pathways and containment
  • Labelling systems and methods
  • Patching facilities and patch cords
  • Testing
  • Administration system
  • Minimum warranty period.

Preparation

Before starting work on the specification, gather and document all the following information if relevant to your installation:

  • A plan (preferably) or dimensions of the areas to be cabled
  • The number of staff requiring IT and/or voice services
  • The services required per workstation, e.g. voice, data
  • Business expansion plans
  • Applications to be supported
  • The highest network speed anticipated during the expected life of the cabling system
  • Ethernet switches and other IT infrastructure hardware to be supported
  • Printers and other peripherals to be supported
  • Voice backbone / distribution requirements
  • The maximum backbone bandwidth expected during the life of the cabling system
  • Building management systems integration
  • Telephone system details
  • Location of Telecommunications Rooms (for edge networking hardware)
  • Location of Equipment Rooms (for core networking hardware)
  • Location of Entrance Facilities for incoming telecommunications lines
  • Locations for cabinets or racks, or space in existing cabinets and racks
  • Cable routes between floors, across floors and between buildings
  • Existing earthing facilities
  • The fire rating requirement of the cable
  • Any known or potential hazards e.g. asbestos, exposed high voltages, etc.

Depending on your knowledge and the complexity of your requirement, expert assistance may be needed to complete the specification.
