Rack-Mounting the Switch

Rack-Mounting the Switch
A rack-mount kit (69-1821-03) is included in the accessory kit for mounting the switch in a standard
19-inch (48.3 cm) four-post equipment rack where the depth of the rack (the distance measured between
the front and the rear posts) does not exceed 32.5 inches (82.5 cm). This rack-mount kit is not suitable
for racks with obstructions (such as a power strip) that could impair access to the switch, four-post rack
enclosures that exceed 32.5 inches (82.5 cm) in depth, or for two-post equipment racks.
An optional rack-mounting kit (C4900M-BKTS-KIT=) is available for installing the chassis in two-post
telco racks and in four-post equipment racks that exceed 32.5 inches (82.5 cm) in depth.
Before installing the chassis in a rack, read the

The equipment rack is the proper size.
– The width of the rack, between the two front mounting strips or rails, must be 17.75 inches
(45.09 cm).
