Chapter 3 Installing the Cisco ASR 901 Mobile Wireless Router

Mounting the Cisco ASR 901 Router

Attaching the Rack-Mounting Brackets

Complete the following tasks to install, replace, or rearrange the rack-mounting brackets so you can then mount the Cisco ASR 901 router in a 19-inch (48.3-cm) equipment rack. You can use the same rack-mounting brackets to front-mount the Cisco ASR 901 router in the equipment rack.

Step 1 Locate the mounting holes of the Cisco ASR 901 router.

Step 2 Align the rack-mounting bracket with the Cisco ASR 901 router and position with the four #6-32 x 0.25-inch screws (provided) (see Figure 3-1for front-mounting).

Step 3 Insert the screws (four places) and tighten using a Number 2 Phillips screwdriver.

Step 4 Repeat Steps 2 and 3 for the other rack-mounting bracket.

Proceed to the next section, “Mounting the Cisco ASR 901 Router in a Rack” to continue the installation.

Mounting the Cisco ASR 901 Router in a Rack

Typically, the Cisco ASR 901 router mounts to a 19-inch (48.3-cm) 2-post equipment rack with rack-mounting brackets that attach toward the front of the router sides. The inside width between the two posts or mounting strips (left and right) must be at least 17.72 to 17.80 inches [45 to 45.21 cm]. For more information about the equipment rack, see “Hardware Description” section on page 1-1.

No vertical clearance is necessary above or below the router when it is mounted in the rack.

To secure the Cisco ASR 901 router to the equipment rack, you must use the two mounting screws (provided) for each side or follow your local practices for installing the router into your equipment rack. Ensure that the rack-mount brackets are securely fastened. For more information, see the “Attaching the
