Chapter 4. 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 24" and 37" deep.

Install this appliance in a physically secure, limited access location only,
such as a service closet or data center.
Situate the appliance in a clean, well-ventilated, dust-free area.
If installed in a closed or multi-unit rack assembly, the ambient operating
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.
Give consideration 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 should be grounded. Give particular attention to power supply
connections other than the direct connections to the branch circuit, such
as the use of power strips.
Use a regulating uninterruptible power supply (UPS) to protect the
appliance from power surges and voltage spikes, and to keep your system
operating in a power failure.
