Space Requirements

The Switch 8800 Family adopts redundant PSUs for AC PSU:

Rated voltage: 100 VAC to 240 VAC, 50 Hz or 60 Hz

Maximum tolerance: 90 VAC to 264 VAC, 50 Hz or 60 Hz

Maximum power output: 1200 W (Switch 8807)/2000 W (Switch 8810/Switch 8814)

For the sake of adequate ventilation and easy equipment maintenance, you are recommended to keep one meter of clearance between the rear/front of the switch cabinet and the wall surface or other devices. If the optional cabinet is desired, the clear height of the equipment room must be more than 3 meters inclusive.

Cabinet-MountingBefore cabinet-mounting the switch, make sure that the cabinet meets the Requirements following requirements:

■Better mount the switch in an open cabinet. However, if you want to mount it in a closed cabinet, make sure of the availability of a good ventilation system.

■Make sure that the cabinet stands steadily enough to support the weight of the switch and the accessories.

■Make sure that the switch fits the cabinet size. Leave some clearance beside the left and right panels of the switch for chassis ventilation.
