Preinstallation Information

Use the following rack-mount installation guidelines
to ensure your safety and optimal performance.
Review all guidelines before you install the chassis in a
rack.
Before you attempt to mount the chassis in a rack:
To help support the 8-slot chassis and 16-slot
chassis while you install it in a rack, install the
mounting shelves that are shipped with the 8-slot
chassis and 16-slot chassis.
For a 7-slot chassis, select a rack that can support
at least 115.65 kg (255 lb), which is three times
the weight of a fully loaded 7-slot chassis and that
provides sufficient vertical space for each chassis
that you want to install.
For an 8-slot chassis, select a rack that can support
at least 215.1 kg (474 lb), which is three times the
weight of a fully loaded 8-slot chassis, and that
provides sufficient vertical space for each chassis
that you want to install.
For a 16-slot chassis, select a rack that can support
at least 265.5 kg (585 lb), which is three times the
weight of a fully loaded 16-slot 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.
Bolt the rack to the floor.
Brace the top of the rack against the wall.
