Planning Your Rack-Mount Installation

Warning
78-15201-04
To install the chassis in a 19-inch or 24-inch rack, follow the instructions
described in these procedures.
A 24-inch rack requires optional mounting hardware.
To prevent bodily injury when mounting or servicing this unit in a rack, you must
take special precautions to ensure that the system 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.
Consider this information when you plan your equipment rack installation:
Enclosed racks must have adequate ventilation. Make sure that the rack is not
•
congested because each unit generates heat. The intake ports of equipment
that is located higher in the rack can draw heat upward from the equipment
that is located near the bottom of the rack. An enclosed rack should have
louvered sides and a fan to provide cooling air.
When mounting a chassis in an open rack, make sure that the rack frame does
•
not block the intake or exhaust ports. If the chassis is installed on slides,
check the position of the chassis when it is seated in the rack.
Baffles can isolate exhaust air from intake air, which also helps to draw
•
cooling air through the chassis. The best placement of the baffles depends on
the airflow patterns in the rack, which you can determine by experimenting
with different configurations.
