Rack-mounting requirements
Before rack-mounting a switch, make sure the rack meets the following requirements:
HP recommends that you mount a switch in an open rack. If you mount a switch in a closed rack,
•
make sure there is a good heat dissipation system.
The rack is steady enough to support the switch and accessories.
•
The switch fits the rack size. Leave some space beside the left and right panels of the switch for
•
chassis heat dissipation.
