How to Install the Rack Mounting Hardware in a Square-Hole Rack
The rack mounting kit consists of adapter brackets, rear braces, shelf rails, cage nuts, and
screws.
Caution –
The server weighs about 180 pounds (100 kg) when fully loaded with components. To
reduce the risk of serious personal injury or equipment damage, use a mechanical lift to install
the server into the rack. If a lift is not available, remove components as described in
“How to
Remove Components to Reduce Weight” on page 49 . This reduces the weight of the server to 80
pounds (45 kg).
Always load equipment into a rack from the bottom up so that it does not become top-heavy
and tip over. Deploy your rack’s anti-tilt bar to prevent the rack from tipping during equipment
installation.
Note –
To install rack mounting hardware in round-hole racks, see “How to Install the Rack
Mounting Hardware in a Round-Hole Rack” on page 64 .
This task requires the following screws and connectors:
