Rack-Mounting the System
A rack-mount kit and cable guides come with the system. The kit is not suitable for racks with
obstructions (such as a power strip) that could impair access to system components. Allow sufficient
clearance around the rack for system maintenance.

Ensuring Proper Airflow

Follow these guidelines to ensure proper airflow:
•Install the system in an open rack whenever possible. If installation in an enclosed rack is
unavoidable, ensure that the rack has adequate ventilation.
•Maintain ambient airflowto ensure normal operation. If the airflow is blocked or restricted, or if the
intake air is too warm, an overtemperature condition can occur.
•Allow at least 6 inches (15.24 cm) of clearance around the ventilation openings of the chassis.
•Avoid placing the system in an overly congested rack or directly next to another equipment rack.
Heat exhaust from other equipment can enter the inlet air vents and cause an overtemperature
condition.
•Equipment near the bottom of a rack might generate excessive heat that is drawn upward and into
the intake ports of the equipment above. The warm air can cause an overtemperature condition in
the equipment above.
•Ensure that cables from other equipment do not obstruct the airflow through the chassis or impair
access to the power supplies or cards. Route cables away from field-replaceable components to
avoid disconnecting cables unnecessarily for equipment maintenance or upgrades.

Stabilizing the System

Follow these guidelines to stabilize the system:
•Install any stabilizers that came with your equipment rack before mounting or servicing the system
in the rack.
•Load the rack from the bottom to the top, with the heaviest system at the bottom.
•Do not stack the system on top of anyother equipment. If the system falls, it can cause severe bodily
injury and damage the equipment.
•Ensure that the shelf is constructed to support the weight and dimensions of the chassis if you are
using an equipment shelf. See Figure1 and Figure 2.
