Cable Labeling and Record Keeping
A reliable cable labeling system is essential when planning and installing a network. Maintaining
accurate records helps you to:
•
Relocate devices easily.
•
Make changes quickly.
•
Isolate faults in the distribution system.
•
Locate the opposite end of any cable.
•
Know the types of network devices that your cabling infrastructure can support.
Consider the following recommendations when setting up a cable labeling system suitable for your
installation:
•
Identify cables by securely attaching a label to all cable ends.
•
Assign a unique block of sequential numbers to the group of cables that run between each pair of
wiring closets.
•
Assign a unique identification number to each distribution rack.
•
Identify all wiring closets by labeling the front panel of your Extreme Networks equipment and
other hardware.
•
Keep accurate and current cable identification records.
•
Post records near each distribution rack. Include the following cable drop information: the cable
source, destination, and jumper location.
Installing Cable
Consider the following recommendations when you connect cable to your network equipment:
•
Examine cable for cuts, bends, and nicks.
•
Support cable using a cable manager that is mounted above connectors to avoid unnecessary weight
on the cable bundles.
•
Use cable managers to route cable bundles to the left and right of the network equipment to
maximize accessibility to the connectors.
•
Provide enough slack—approximately 2 to 3 inches (5.08-7.62 cm)— to provide proper strain relief as
shown in Figure 11.
•
Bundle cable using velcro straps to avoid injuring cables.
•
If you build your own cable, ensure that cable is properly crimped.
•
When installing a patch panel using twisted pair wiring, untwist no more than 1 inch (2.54 cm) of
the cable to avoid RF interference.
•
When required for safety and fire rating requirements, use plenum-rated cable. See your local
building codes for determining when it is appropriate to use plenum-rated cable, or refer to IEC
standard 850.
•
Keep all ports and connectors free of dust.
