Installation Location

- Before installing the switch, plan its location and

orientation relative to other devices and equipment:

•

In the front of the switch, leave at least 7.6 cm (3 inches) of space for
the twisted-pair and fiber-optic cabling.

•

In the back of the switch, leave at least 3.8 cm (1 1/2 inches) of space
for the power cord.

•

On the sides of the switch, leave at least 7.6 cm (3 inches) for cooling,
except if the switch is installed in an open EIA/TIA rack.
