• Four post, 19-inch equipment rack. Inner clearance (the width between the inner sides of the two posts
or rails) must be at least 19 inches (48.26 cm). The height of the chassis is 3.47 inches (8.8 cm). Airflow
through the chassis is from front to back.
When handling the chassis, always follow proper lifting practices. See the Chassis-Lifting Guidelines ”
section on page 5-23 .
Note
The Cisco ASR 1002 Router can be installed with both front or rear rack-mount brackets.
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
t_Verifying_Rack_Dimensions_1202731.xml.
SUMMARY STEPS
1. Mark and measure the distance between two holes on the left and right mounting rails.
2. Measure the space between the inner edges of the left front and right front mounting flanges on the
equipment rack.
DETAILED STEPS
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 17.25 inches (43.8 cm) wide and
fits between the mounting posts on the rack.
