Prerequisites
Before installing the Cisco ASR 907 Router, it is important to prepare for the installation by:
• Preparing the site (site planning) and reviewing the installation plans or method of procedures (MOP)
• Unpacking and inspecting the Cisco ASR 907 Router
• Gathering the tools and test equipment required to properly install the Cisco ASR 907 Router
For more instructions on how to prepare for the installation of the Cisco ASR 907 Router, see Preparing for
Installation.
Installing the Router in a Rack
The following sections describe how to install the Cisco ASR 907 Router in a rack:
Installing the Chassis Brackets
The chassis is shipped with mounting brackets that can be installed on the front or rear of the chassis. To
install the brackets on the front of the chassis, perform these steps:

Procedure
Step 1 Remove the rack-mount brackets from the accessory kit and position them beside the router chassis.
The figure below shows how to attach the brackets on the Cisco ASR 907 Router for a 19-inch EIA rack and
300 mm ETSI Cabinet.
Figure 1: Attaching Mounting Brackets for a 19-inch EIA Rack and 300 mm ETSI Cabinet
Step 2 Position one of the brackets against the chassis side, and align the screw holes.
Step 3 Secure the bracket to the chassis with the screws removed when performing Step 1. The recommended
maximum torque is 28 in.-lb (3.16 N-m).
The A907-FAN-E fan tray with filter (A907-FAN-F) cannot be mounted using the mounting screws that are
supported for fan tray. This is not an issue with the FAN tray filter blank panel (A907-FAN-F-B). We
recommend that you use the short screws provided in the following rack mount kits to avoid interference of
the air filter during rack mounting and while replacing the fan tray with the fan tray filter (A907-FAN-E):
• 19" rack mount kit (A907-RCKMT-19IN)
• ETSI rack mount kit (A907-RCKMT-ETSI)
What to do next
Repeat Step 2 and Step 3 for the other bracket.
Installing the Router Chassis in the Rack
The procedures in this section apply to both horizontal and vertical mounting of the router in a rack.

Installing the Router Chassis in the Rack

To install the router chassis in the equipment rack, perform these steps:
Procedure
Step 1 Position the chassis in the rack as follows:
• If the front of the chassis (front panel) is at the front of the rack, insert the rear of the chassis between
the mounting posts.
• If the rear of the chassis is at the front of the rack, insert the front of the chassis between the mounting
posts.
Step 2 Align the mounting holes in the bracket (and optional cable guide) with the mounting holes in the equipment
rack.
Do not use interface module and power supply ejector handles to lift the chassis; using the handles
to lift the chassis can deform or damage the handles. Installing the Chassis to support the Japanese
JIS Rack Standard.

Figure 4: Installing the Chassis in a 300 mm ETSI Cabinet
The router can be mounted in an ETSI rack but the required bend radius for the cables and fibers
within the 300 mm ETSI specification cannot be maintained.
If you want to mount the router in ETSI cabinets, you need to have a custom-made cabinet front
door to meet the fiber bend radius requirement.
Note
Step 3 Install the 8 or 12 (4 or 6 per side) 12-24 x 3/4-inch or 10-32 x 3/4-inch screws through the holes in the bracket
and into the threaded holes in the equipment rack posts.
Step 4 Use a tape measure and level to verify that the chassis is installed straight and level.
Installing Plenum A907-F2B-AIR-U Assembly and Chassis in the Rack
Procedure
Step 1 Position the air baffle and the side plate to the plenum. Secure the air baffle using a maximum torque of 11.5
in.-lb (1.3 N-m). See figure below.

Step 2 Position the plenum assembly to the rack and secure the cable brackets to the rack using a torque of 11.5 in.-lb
(1.3 N-m). See figure below.
For a 19-inch rack installation, the rack has to have a flat post.

Step 4 Position cable guides on the router chassis.
Step 5 Ensure to select the 21-inches or 23-inches adapter for your plenum based on your rack size.
The 19-inches bracket is an integral part of the plenum base.

Step 6 Position the plenum assembly to the rack and secure the cable brackets to the rack using a torque of 11.5 in.-lb
(1.3 N-m). See figure below.
For a 19-inch rack installation, the rack has to have a flat post.

Installing the Chassis in the Air Plenum
Ensure that the router is not installed in the Air Plenum while mounting it on the rack.
Note
For instructions on mounting the air plenum on the rack.
Procedure
Step 1 Position the chassis so that the rear of the chassis is at the front of the plenum. See the figure below.
Step 2 Slide the chassis into the plenum so that the front of the chassis is in flush with the mounting rails and brackets.
