Prerequisites
Before installing the 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).
See Site Planning section.
• Unpacking and inspecting the router. See Chassis-Lifting Guidelines section.
• Gathering the tools and test equipment required to properly install the router. See Tools and Equipment
section.
For more instructions on how to prepare for the installation of the router, see Preparing for Installation section.

Installing the Router in a Rack
Each Cisco ASR 920 Series Aggregation Services Router router includes rack-mounting brackets. Using the
rack-mounting brackets, you can mount the router in a 19-inch, 23-inch, or an ETSI rack that conforms to the
EIA-310-D specification.
Using the two rack-mounting brackets for mounting, you can recess the router in the equipment rack. This
arrangement provides extra space in front of the router for the cables and allows you to close the doors of
racks equipped with front-close doors.
To attach or replace the rack-mounting brackets, see the Attaching Brackets to the Router section.
The rack-mounting brackets are slotted to allow the router to be mounted in racks with EIA 1.25-inch (3.175-cm)
or WECO 1.0-inch (2.54-cm) hole spacing. When installed in the rack, the router requires one EIA 1.75-inch
(4.4-cm) vertical mounting space (or 1 rack unit [RU]) for mounting (see the Mounting the Router in a Rack
section).
Allow clearance on either side of the router for cooling air to be drawn in through the right side and circulated
through the chassis and out the three-fan exhaust ports mounted on the other side of chassis.
Caution
The sections describe how to install the router in a rack. The procedures in this section apply to both horizontal
and vertical mounting of the router in a rack:
Attaching Brackets to the Router
The bracket orientation and the brackets that you use depend on whether you are attaching the brackets for a
19-inch, 23-inch, or an ETSI rack. The following figure shows the types of mounting brackets.

• For 19-inch racks, use part number 700-39959-01 (see Attaching Brackets for 19-Inch Racks section).
• For 23-inch racks, use part number 700-40065-01 (see Attaching Brackets for 23-Inch Racks section).
• For ETSI racks, use part number 700-40067-01 (see Attaching Brackets for ETSI Racks section).
The bracket mounting screws are pre-installed on the router. Depending on the bracket mounting position of
the chassis, you must remove the appropriate screws, fix the bracket, and install the screws again.

Mounting the Router in a Rack
Perform the steps given below to mount the router into the equipment rack.
To secure the 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 Brackets to the Router section.
Note
Procedure
Step 1 Locate the equipment rack position where you plan to install the router.
Step 2 Verify that there are no obstructions and ensure that the equipment rack is stabilized.
Step 3 Determine whether you are mounting the router on a 19-inch, 23-inch, or an ETSI rack. Rack-Mounting
Brackets figure shows the types of mounting brackets.
Step 4 Determine the mounting position (Front-, Mid-, or Rear-mounting) of the router. (For 19-inch racks, see
Attaching Brackets for 19-Inch Racks section. For 23-inch racks, see Attaching Brackets for 23-Inch Racks
section. For ETSI racks, see Attaching Brackets for ETSI Racks section.)
Step 5 Locate the mounting holes of the router.
Step 6 Align the rack-mounting bracket with the router and position with the four #6-32 x 0.25-inch screws (provided).
Step 7 Insert the screws (four places) and tighten using a Number 2 Phillips screwdriver (each side).
Step 8 Position the router in the equipment rack lining up the bracket holes on the router with the holes on the rack
and secure with four #6-32 x 0.25-inch mounting screws (two on each side).
Step 9 Tighten the screws using a 1/4-inch flat-blade screwdriver (each side). The recommended maximum torque
is 10 in.-lb.
Installing the Router Chassis in the Rack
Ensure adequate air flow when mounting the router in a rack. For more information, see the Air Flow Guidelines
section in the Cisco ASR-920-12SZ-IM and ASR-920U-12SZ-IM Aggregation Services Router Hardware
Installation Guide.

Mounting the Router in a Rack

Install the cable guides before installing the router in a 19-inch EIA rack. See the Attaching the Cable Guides
section in the Cisco ASR-920-12SZ-IM and ASR-920U-12SZ-IM Aggregation Services Router Hardware
Installation Guide.
Note
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.
The following figure shows how to install the router in a 19-inch EIA rack.
Figure 5: Installing the Chassis in a 19-inch EIA Rack
Step 3 Install the four M6x12mm zinc-plated steel 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.
Attaching the Cable Guides
The Cisco ASR 920 Series Router supports the following cable guides:

• A920-CBL-GUIDE (left and right)—help in routing the cables from all components on the front panel
thereby enabling a proper cable-bending radius.
If the chassis is mounted using 19-inch brackets, you must assemble the cable guides before installing the
chassis on the rack.
Note
To install the cable guides, perform these steps:
Procedure
Step 1 Position the cable guide-left and cable guide-right against the front of the chassis and align the four screw
holes, as shown in the following figure.
Figure 6: Cable Guide Installation For 19-inch Rack Brackets
Figure 7: Cable Guide Installation For ETSI Rack Brackets
Step 2 Secure the cable guides with the four M6x12mm screws supplied with the cable kit. The recommended
maximum torque is 3N-m.
