Equipment should be mounted into a rack so that the amount of airflow required for safe operation
is not compromised.
Mechanical Loading
Equipment should be mounted into a rack so that a hazardous condition does not arise due to
uneven mechanical loading.
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.).
Warning: To prevent bodily injury when mounting or servicing this unit in a rack, you
must take special precautions to ensure that OneBlox remains stable. The following
guidelines are provided to ensure your safety.
• This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
•
When mounting this unit in a partially filled rack, load the rack from the bottom
to the top with
the heaviest component at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing
the unit in the rack.
5.1.3 - Installing OneBlox into a Rack
5.1.3.1 - Separating the Sections of the Rack Rails
The OneBlox package includes two rail assemblies in the rack mounting kit. Each assembly
consists of two sections: an inner fixed OneBlox rail that secures directly to the server OneBlox and
an outer fixed rack rail that secures directly to the rack itself. You should also refer to the
installation instructions that came with the rack unit you are using.
5.1.3.2 - Installing the Inner Rail Extension
OneBlox includes a set of inner rails in two sections: inner rails and inner rail extensions. The inner
rail extension is attached to the inner rail to mount the OneBlox in the rack.
