Rack-Mounting Guidelines
Chassis height is sometimes measured in rack units (RU or just U) where 1 RU or 1 U equals 1.75 in
Note
(44.45 mm). A typical server rack is 42 RU or 42 U in height.
If the rack is on wheels, ensure that the brakes are engaged and that the rack is stabilized.
Caution
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special
Warning
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.
To maintain proper air circulation through the Catalyst switch chassis, we recommend that you maintain
Note
a minimum 6-inch (15 cm) separation between a wall and the chassis air intake or a wall and the chassis
air exhaust. You should also allow a minimum separation of 12 inches (30.5 cm) between the hot air
exhaust on one chassis and the air intake on another chassis. Failure to maintain adequate air space can
cause the chassis to overheat and the system to fail. On Catalyst switch chassis in which the airflow is
from front to back, the chassis may be placed side-by-side.
