Make sure that the two bottom-support rails are level with one another. If they are not level, adjust the higher
rail down to the level of the lower rail.
Note
When the bottom-support rails are installed at the lowest possible RU and are level, you are ready to install the chassis
in the rack or cabinet.
Attaching Bottom-Support Rails to a Four-Post Rack
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).
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.
