Installing the Chassis Brackets
The chassis is shipped with mounting brackets that can be installed on the front or rear of the chassis. To
install the brackets on the front of the chassis, perform these steps:
Procedure
Step 1 Remove the rack-mount brackets from the accessory kit and position them beside the router chassis.
Step 2 Position one of the brackets against the chassis side, and align the screw holes.
19-inch EIA Rack
The following figures show how to attach the brackets at the front, middle, and rear positions on the Cisco
ASR-920-24SZ-IM Router for a 19-inch EIA rack.

Step 3 Secure the bracket to the chassis with the screws removed when performing Step 1. The recommended
maximum torque is 10 in.-lb.
Step 4 Repeat Step 3 for the other bracket.
Installing the Router Chassis in the Rack
Ensure adequate air flow when mounting the router in a rack. For more information, see the Air Flow Guidelines
section.
Note
Install the cable guides before installing the router in a 19-inch EIA rack. See Attaching the Cable Guides
section.
Note
To install the router chassis in the equipment rack, perform these steps:
Procedure
Step 1 Position the chassis in the rack as follows:
• If the front of the chassis (front panel) is at the front of the rack, insert the rear of the chassis between
the mounting posts.
• If the rear of the chassis is at the front of the rack, insert the front of the chassis between the mounting
posts.

Step 4 Use a tape measure and level to verify that the chassis is installed straight and level.
Attaching the Cable Guides
The Cisco ASR-920-24SZ-IM Router supports the following cable guides:
• A920-CBL-GUIDE (left and right)—help in routing the cables from all components on the front panel
thereby enabling a proper cable-bending radius.
If the chassis is mounted using 19-inch brackets, you must assemble the cable guides before installing the
chassis on the rack.
Note
To install the cable guides, perform these steps:
Procedure
Step 1 Position the cable guide-left and cable guide-right against the front of the chassis and align the four screw
holes, as shown in the figure for 19-inch rack and in the figure for other racks using standard kit.
