Extreme Networks BlackDiamond 10808 Installation Manual page 25

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 to 7.62 cm), to provide proper strain relief as
shown in Figure 5.
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 radio frequency (RF) interference.
Discharge the RJ45 Ethernet cable before plugging it into a port on the switch.
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.
