Rack-Mounting the Router Chassis
The router chassis is installed in a front-mounted position, as shown in Figure 1-7 for the
Cisco ASR 9001 Router chassis.
In a front-mounted position, the chassis rack-mounting flanges are secured directly to the rack posts.
The PID of the rack mounting kit for Cisco ASR 9001 Router and Cisco ASR 9001-S Router is
ASR-9001-2P-KIT=.
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 Figure 2-2.
Step 1 Mark and measure the distance between two holes on the left and right mounting rails.
The distance should measure 18.31 inches ± 0.06 inches (46.5 cm ± 0.15 cm).
Note Measure the distance for pairs of holes near the bottom, middle and top of the equipment rack
to ensure that the rack posts are parallel.
Step 2 Measure the space between the inner edges of the left front and right front mounting flanges on the
equipment rack.
The space must be at least 17.7 inches (45 cm) to accommodate the chassis, which is approximately
17.45 in. (44.32 cm) wide, and fits between the mounting posts on the rack.

Installing the Chassis in a 2-Post Rack
Two people must lift the router chassis using the handles on the sides. To accommodate racks with
different hole patterns in their mounting flanges, the chassis rack-mounting flanges have three oblong
screw holes on each side.
