Chapter 11 Cisco ASR 1001 Router Overview and Installation

Rack-Mounting the Cisco ASR 1001 Router

The Cisco ASR 1001 Router can be installed in an existing rack with equipment or in an empty rack with

no equipment: The chassis can be mounted in either rack types:

• Two-post rack, either 19 inch or 23 inch. 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.

Note If you are using a two-post rack secure the rack to the floor surface to prevent tipping and

avoid bodily.

• 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 1.71 inches (43.43

mm). Airflow through the chassis is from front to back.

Note When handling the chassis, always follow proper lifting practices. See the “Chassis-Lifting Guidelines”

section on page 5-23.

The Cisco ASR 1001 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 Figure 11-14.

Figure 11-14 Verifying Equipment Rack Dimensions

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 for pairs of holes near the bottom, middle and top of the equipment rack to ensure that

the rack posts are parallel.
