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.
Prepare for installation
Choose a setup location
Decide on a suitable location for the rack unit that holds your appliance.

Prepare the rack
1. Ensure that the leveling jacks on the bottom of the rack are fully extended to the floor with the full
weight of the rack resting on them.
v In single rack installations, attach stabilizers to the rack.
v In multiple rack installations, couple the racks together.
2. Check that the rack is stable before extending an appliance from the rack.
3. Extend only one appliance at a time. Extending two or more simultaneously can destabilize the rack.

Comments
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.
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.
Avoid areas where heat, electrical noise, and electromagnetic fields are generated.
