Preinstallation Guidelines

Rack-Mount Installation Guidelines
Before you attempt to mount the chassis in a rack:
■
Select a rack that can support at least 115.65 kg
(255 lb), which is three times the weight of a fully
loaded Switch 4007 chassis, and that provides
sufficient vertical space for each chassis that you
want to install.
■
Make certain that the rack that you use is properly
aligned and is squared. Use a framing square to
ensure that the rack is squared.
■
To maintain proper cooling in the chassis and to
maintain safety compliance, make certain that
blank faceplates cover any empty slots.
■
Bolt the rack to the floor.
■
Brace the top of the rack against the wall.
