Installing the Bottom-Support Rails
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
• Verify that the bottom-support rails kit is included in the switch accessory kit, see
Step 1
Position one of the two adjustable bottom-support rails at the lowest possible RU in the rack or cabinet. Adjust the length
of each rail so that it stretches from the outer edges of the front and rear vertical mounting rails on the rack. Be sure that
there is at least 13 RU (22.75 in [57.8 cm]) 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).
