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. To see translations of
the warnings that appear in this publication, refer to the Regulatory Compliance
and Safety Information document that accompanied this device.
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.
The following information will help 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. Heat generated by equipment
near the bottom of the rack can be drawn upward into the intake ports of the
equipment above. 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 can be found by experimenting with
different configurations.
When equipment installed in a rack (particularly in an enclosed rack) fails,
•
try operating the equipment by itself, if possible. Power off other equipment
in the rack and in adjacent racks to allow the unit under test a maximum of
cooling air and clean power.
Install the Cisco RPS and the external device to which it will connect in
•
adjacent shelves in a rack.
