•
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.
Caution
Unshielded twisted pair (UTP) cable can build up ESD 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 RJ-45 connector into a LAN static discharge device or
use an equivalent method.
•
Use plenum-rated cable when it is necessary for safety and fire rating requirements. Consult your
local building codes to determine when it is appropriate to use plenum-rated cable, or refer to IEC
standard 850.
•
Keep all ports and connectors free of dust.
