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.
