What to do next
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.

Warning
Before you begin
Before you can install the bottom support rails for the chassis, you must do the following:
• Verify that a four-post rack or cabinet is installed and secured to the concrete subfloor (see
).
• If any other devices are stored in the rack or cabinet, verify that they are located below where you plan
to install the switch. Also, verify that lighter devices in the same rack are located above where you plan
to install this switch.
• Verify that the bottom-support rails kit is included in the switch accessory kit .
Step 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 (see the following figure).
You can expand the rail so that its mounting brackets are spaced between 24 to 32 inches (61.0 to 81.3 cm).
