Extreme networks 12802 User Manual

BlackDiamond 12800 Series Switches Hardware Installation Guide

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 

.

●

Bundle cable using velcro straps to avoid injuring cables.

●

If you build your own cable, be sure 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 RJ-45 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.
