•
Identify cables by securely attaching labels 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 equipment 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 equipment rack. For each cable drop, include information about the cable
source, destination, and jumper location.
Installing Cable
When you connect cable to your network equipment, keep the following things in mind.
•
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 5 to 7.5 cm (2 to 3 in), to provide proper strain relief as shown
in Figure 6 on page 23.
•
Bundle cable using hook-and-loop straps to avoid injuring cables.
•
If you build your own cable, be sure that connectors are properly crimped.
•
When installing a patch panel using twisted pair wiring, untwist no more than 2.5 cm (1 in) of the
cable to avoid radio frequency (RF) interference.
•
Discharge the RJ45 Ethernet cable before plugging it into a port on the switch.
Caution
Unshielded twisted pair (UTP) cable can build up electrostatic charges when being pulled
into a new installation. Before connecting any category 5 UTP cable to the switch,
discharge ESD from the cable by plugging the RJ45 connector into a LAN static discharge
device or use an equivalent method.
