Step 4 Finger-tighten the screws to the rack rails on each side of the chassis. Space the screws evenly between the
top and bottom of the chassis.
Step 5
(Optional) For optional earthquake protection for the Cisco ASR 9010 Router or Cisco ASR 9006 Router,
two side brackets must be mounted to the chassis for attachment to the posts (5” channel width) of a GR-63
Zone 4 Seismic 2-post rack (
Figure 112: Installing the Cisco ASR 9010 Router Chassis in a Seismic 2-Post
Rack, on page 106 ).
a) Attach the side brackets to the left and right side of the chassis by finger-tightening five screws through
each bracket into the chassis.
b) Attach the side bracket front flanges to the rack posts by finger-tightening four screws through each bracket
flange into the mounting rails of the rack.
c) Fully tighten the five screws on each side bracket to secure the brackets to the chassis.
d) Fully tighten the four screws on each side bracket flange to secure the brackets to the rack rails.
Step 6 Fully tighten all five screws on the chassis mounting flanges on each side to secure the chassis to the rack
rails.
Installing the Chassis in a 4-post Open Rack
To mount the Cisco ASR 9010 Router, Cisco ASR 9906 Router, Cisco ASR 9910 Router, Cisco ASR 9922
Router or Cisco ASR 9912 Router chassis in a 4-post open rack, two side brackets must be attached to the
chassis and the rear posts. See
Figure 120: Installing the Cisco ASR 9010 Router Chassis in a 4-Post Rack,
on page 114 for the Cisco ASR 9010 Router , Figure 123: Installing the Cisco ASR 9906 Router Chassis in a
4-Post Rack - Right view, on page 116 for the Cisco ASR 9906 Router, and Figure 126: Rack Mount Installation
Kit for the Cisco ASR 9922 Router and Cisco ASR 9912 Router, on page 119 for the Cisco ASR 9922 Router
and Cisco ASR 9912 Router.
To mount the Cisco ASR 9006 Router ( Figure 121: Installing the Cisco ASR 9006 Router Chassis in a 4-Post
Rack, on page 115 ) or Cisco ASR 9904 Router ( Figure 122: Installing the Cisco ASR 9904 Router Chassis in
a 4-Post Rack ) in a 4-post open rack, extra brackets are not required.
Preparing the 19 Inch 45-RU Rack
To prepare the 19 Inch 45-RU rack that will contain either the Cisco ASR 9922 Router chassis or Cisco ASR
9912 Router chassis:
Procedure
Step 1 Install the two guide rails into the bottom of the rack ( Figure 126: Rack Mount Installation Kit for the Cisco
ASR 9922 Router and Cisco ASR 9912 Router, on page 119 ).
The two guide rails at the bottom of the rack are included in the ASR-9922-ACC-KIT and ASR-9912-ACC-KIT
accessory kits. Use screws to fasten these two guide rails into the front and rear rails of the rack.
The two guide rails have six holes (three per rail) that accommodate 12-24 or M6 screws. If you want to use
smaller 10-32 screws, you must use them with bushings to fit the larger holes (
Figure 77: One 10-32 Screw
with Bushings in Guide Rail Holes , on page 73 ). The bottom rail is keyed to the EIA mounting hole pattern.
Install the rails at the first RU location. The rear rack mount brackets are installed by aligning the bracket
mounting holes to the holes on the rear cover of the chassis.
