Note If the switch is installed in a closed or multirack assembly, the temperature around
it might be greater than normal room temperature.
• Cabling is away from sources of electrical noise, such as radios, power lines,
and fluorescent lighting fixtures. Make sure that the cabling is safely away
from other devices that might damage the cables.
• For sites requiring compliance to Telcordia GR-1089-CORE Intra-building
Lightning requirements, all 10/100 and 10/100/1000 ports must be connected
with shielded cable grounded at both ends.
