Rack-mount procedure
1. Ensure the rack has sufficient space for the switch and its cables. For the
switch's requirements, see
2. Install cage nuts at the front of the rack so they are ready for the rack-
mount screws in the following steps.
3. Unpack the switch and remove the rubber feet.
It may be helpful to temporarily remove the PSU or FOM so that the switch
is lighter and easier to manipulate during installation. For more information,
see the Removable Power Supply and Fan Installation Guide.
4. Screw one bracket to each side of the switch using the M4 screws provided.
5. Mount the switch into the rack from the front, and tighten the 4
rack-mount screws.
Two people are required at this point. One person can lift the switch into
the rack and attach it to the front rails while the second person safely
supports it from the rear.
