Chapter 2      Installing the Cisco MDS 9148S Switch
    Installing the Switch in a Cabinet with Insufficient Front Clearance
Step 4 Stabilize the switch in the rack by attaching the front rack-mount brackets to the rear rack-mounting 
rails:
a. Insert two screws (12-24 or 10-32, depending on rack type) through the holes in one of the front 
rack-mount brackets and into the threaded holes in the back rack-mounting rail (see Figure 2-4). For 
racks with square holes, first install the 12-24 cage nuts.

b.
Repeat for the front rack-mount bracket on the other side of the switch.
Tip If the chassis exceeds the 1-RU space on the low side of the rack, you may have difficulty installing other 
equipment. In this situation, loosen the screws on the front and back rails of the chassis and raise it to 
the top of the RU space by pushing the chassis up until it cannot go any further. Then retighten the screws 
while keeping the chassis in the elevated position.
