Chapter 3. Install the appliance into a rack
Many racks are on the market, which means that the assembly procedure might differ slightly. This rail
fits a rack between 28.5" and 35.5" deep.
Prepare for installation
Assemble tools
A #2 Phillips screwdriver and a cage nut tool are needed to install and secure the rails to the appliance.
Wear a set of leather work gloves when racking the appliance. They help to get a grip on the appliance
and avoid injury from any metal edges.
CAUTION:
Do not use of any sort of hammer to secure the rails on the appliance. A hammer might damage the
drives within the chassis and possibly void the warranty.
Choose a setup location
Decide on a suitable location for the rack unit that holds your appliance.

Install this appliance in a physically secure, limited access location only, such as a
service closet or data center.
Situate it in a clean, well-ventilated, dust-free area.
temperature of the rack environment might be greater than the ambient
temperature of the room. Install the equipment in an environment compatible with
the maximum rated ambient temperature (TMRA) for the appliance.
Mount the equipment into a rack so that the amount of airflow that is needed for
safe operation is not compromised. Leave enough clearance in front of the rack to
open the front door completely (36 inches). Leave about 36 inches of clearance
behind the rack for sufficient airflow and ease in servicing.
Mount the equipment into a rack so that a hazardous condition does not arise due
to uneven mechanical loading. Install heavier items into the bottom of the
equipment rack to keep the rack stable. Mount equipment in a rack evenly to
prevent a later hazard.
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.
Note: The maximum current draw is printed on a label on the appliance power
supplies. The system can draw more than 15 Amps at startup (inrush current).
A reliable ground must be maintained always. To ensure grounding, the rack itself
must be grounded. Particular attention should be given to power supply
connections other than the direct connections to the branch circuit, such as the use
of power distribution units.
