2: Server Installation
Circuit Overloading
Consideration should be given to the connection of the equipment to the power supply circuitry
and the effect that any possible overloading of circuits might have on overcurrent protection and
power supply wiring. Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.
Reliable Ground
A reliable ground must be maintained at all times. To ensure this, the rack itself should be
grounded. Particular attention should be given to power supply connections other than the direct
connections to the branch circuit (i.e. the use of power strips, etc.).
Install the System into a Rack
This section provides information on installing the SGI Altix XE250 into a rack. If the system has
already been mounted into a rack, refer to
“Check the Node Board Setup” on page 23 . There are
a variety of rack units on the market, which may mean the assembly procedure will differ slightly.
You should also refer to the installation instructions that came with the rack unit you are using.
Identify the Sections of the Rack Rails
You should have received two rack rail assemblies in the rack mounting kit. Each assembly
consists of two sections: an inner fixed chassis rail that secures directly to the server chassis and
an outer fixed rack rail that secures directly to the rack itself (refer to
Figure 2-2 ). Two pairs of
short brackets to be used on the front side of the outer rails are also included.
