Installation Location
Before installing the switch, plan its location and orientation relative to other
devices and equipment:
In the front of the switch, allow at least 7.6 cm (3 inches) of space for the
twisted-pair and fiber-optic cabling.
In the back of the switch, allow at least 10.2 cm (4 inches) of space for the
power cord and cooling.
On the sides of the switch, leave at least 7.6 cm (3 inches) for cooling.
Fiber Optic Cables
100Base-FX
(on the 100-FX
