Preinstallation Guidelines

Use the following installation guidelines to ensure
your safety and optimal performance. Review all
guidelines before you install the Switch 4007.

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.
