Labelling Structured Cabling Systems

All elements of the structured cabling system should be labelled in accordance with ISO/IEC 14763-1.

Items to be included within the labelling scheme include:

  • Patch panels
  • Horizontal cables (at both ends)
  • Backbone cables (at both ends)
  • Outlets
  • Cabinets
  • Earthing Points

 

All labelling must be permanent and completed prior to testing.  The labels must be designed to last the lifetime of the cabling system and must be legible and UV stable. Under no circumstances should the labels be hand written or permanent markers used to identify the components or cables.

Labels on cables should be of the wrap around type.  The label reference must be identical at both ends of the cable. 

Labels used on consolidation points, patch panels and outlets and for cabinets and earthing points should ideally be of the engraved type and be either self-adhesive or stud mounted.

The patch panel numbering sequence should start at the top left of the cabinet or frame and work across and down.

All equipment cabinets and patching frames must be clearly labelled using the customer’s numbering scheme, which should be agreed prior to project commencement.  Labels are required for each cabinet and frame vertical for all units being supplied by the installer.  Labelling should be applied to the front and rear of each cabinet and frame.

 

The format of the labelling scheme should be agreed with the end user.

 

Examples of labelling schemes are as follows:

Outlets and Horizontal Cables

Typical configuration = F/C/P/N, where:

F                =          Floor Number

C                =          Cabinet Reference

P                =          Panel

N                =          Port Number of Panel

e.g. G/A/1/24     =   Ground Floor, Cabinet A, Panel 1, Port 24

 

Panels for Horizontal Cables

Typical configuration = F/C/P, where:

F                =          Floor Number

C                =          Cabinet Reference

P                =          Panel

e.g. 1/F/10  =          First Floor, Cabinet F, Panel 10

 

Backbone cabling

Typical configuration = B/F/C/P/N, where:

B                =          Building

F                =          Floor Number

C                =          Cabinet Reference

P                =          Panel

N                =          Port Number of Panel

e.g. A/G/C/2/4 – C/1/D/1/4      =       Building A, Ground Floor, Cabinet C, Panel 2, Port 4 to
                                                         Building C, First Floor, Cabinet D, Panel 1, Port 4
