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 45: Verifying Equipment
Rack Dimensions, on page 49.
Procedure
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).
Measure for pairs of holes near the bottom, middle and top of the equipment rack to ensure that the
rack posts are parallel.
Note
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 17.50
inches (44.45 cm) wide and fits between the mounting posts on the rack.

Installing the Chassis in a 2-Post Rack
This section describes how to install the chassis in a 2-post telco-style rack. Two people can lift an empty
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 groups of eight oblong screw holes on each
side.
An empty chassis weighs approximately 150 pounds (68 kg). You need two people to slide the chassis into
the equipment rack safely.
Caution
This figure shows the orientation of the Cisco ASR 9010 Router chassis to the rack posts (3” or 6” channel
width) of an industry-standard 2-post rack and components used in the installation.
