SPARC T4-1 Server Installation Guide • August 2013
Caution –
Equipment Loading:
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-tip 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, install the
equipment only in an environment compatible with the maximum ambient
temperature (Tma) specified for the server.
Caution –
Reduced Air Flow
: Install the equipment in a rack so that the amount of
air flow is adequate for the safe operation of the equipment.
Caution –
Mechanical Loading
: Mount the equipment in the rack so that the weight
is distributed evenly. A hazardous condition can exist with uneven mechanical
loading.
