Rack-Mounting The Router Chassis; Verifying Rack Dimensions - Cisco ASR 9000 Series Installation Manual

Chapter 2 Unpacking and Installing the Chassis

Rack-Mounting the Router Chassis

The router chassis is installed in a front-mounted position, as shown in
9010 Router,
Figure 1-26
In a front-mounted position, the chassis rack-mounting flanges are secured directly to the rack posts.
The Cisco ASR 9922 Router and Cisco ASR 9912 Router are designed to mount in only 4-post racks.
Note

Verifying Rack Dimensions

Before you install the chassis, measure the space between the vertical mounting flanges (rails) on your
equipment rack to verify that the rack conforms to the measurements shown in
Mark and measure the distance between two holes on the left and right mounting rails.
Step 1
The distance should measure 18.31 inches ± 0.06 inches (46.5 cm ± 0.15 cm).
Note
Measure the space between the inner edges of the left front and right front mounting flanges on the
Step 2
equipment rack.
The space must be at least 17.7 inches (45 cm) to accommodate the chassis, which is approximately
17.50 inches (44.45 cm) wide and fits between the mounting posts on the rack.

the rack posts are parallel.
