Safety Precautions When Rackmounting
the Server
This section describes safety precautions you must follow when installing the server
into a rack.
Caution – Deploy the anti-tilt bar or legs on the equipment rack before beginning an
installation.
Caution – Always load equipment into a rack from the bottom up so that the rack
will not become top-heavy and tip over. Deploy your rack's anti-tilt bar to prevent
the rack from tipping during equipment installation.
Caution – Elevated operating ambient temperature: If the server is installed in a
closed or multi-unit rack assembly, the operating ambient temperature of the rack
environment might be greater than room ambient temperature. Therefore,
consideration should be given to installing the equipment in an environment
compatible with the maximum ambient temperature (Tma) specified for the server.
For server environmental requirements, see
page 10.
