v Verify that the bottom-support rails kit is included in the switch accessory kit
(Unpack and inspect the chassis shipment for completeness and damage).
About this task
The bottom-support rails support the weight of the switch chassis in the rack or
cabinet. To maximize the stability of the rack, you must attach these rails at the
lowest possible rack unit (RU).
Note: 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:
v This unit should be mounted at the bottom of the rack if it is the only unit in
the rack.
v
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.
v If the rack is provided with stabilizing devices, install the stabilizers before
mounting or servicing the unit in the rack.
Procedure
1. Position one of the two adjustable bottom-support rails at the lowest possible
RU in the rack or cabinet and adjust the length of the rail so that it stretches
from the outer edges of the front and rear vertical mounting rails. Be sure there
is at least 9 RU of vertical space above the rails to install the chassis.
You can expand the rail so that its mounting brackets are spaced between 24 to
32 inches (61.0 to 81.3 cm).
