Installing the Rack-Mount Shelf Kit
Before installing the chassis, you should install the rack-mount shelf kit that is included as part of the accessory
kit. The rack-mount shelf kit is shipped as part of the Catalyst 6880-X switch accessory kit. It contains two
shelf brackets, a support shelf, and screws. The shelf brackets attach directly to the rack and help support the
weight of the chassis.
Required Tools
These tools and equipment are required to install the rack-mount shelf kit:
• Number 1 and number 2 Phillips screwdrivers
• 3/16-inch flat-blade screwdriver
• Tape measure and level
Installing the Shelf Brackets and Shelf
On many older equipment racks, the rack posts are prethreaded to accept either 10-32 or 12-24 screws.
Note
Newer rack enclosure posts might not be prethreaded. These rack enclosure posts require that you install
10-32 or 12-24 clip nuts or cage nuts to secure the rack-mount screws. The clip nuts or the cage nuts are
not included as part of the accessory kit and must be obtained on your own.
Before you install the shelf brackets, determine the clearance between the insides of the left and right rails of
your rack system:
• If the distance between the insides of the rails is 17.5 inches (44.45 cm), then follow the steps in "Installing
• If the distance between the insides of the rails is 17.75 inches (45.09 cm), then follow the steps in
