Cisco ASR-920-12SZ-IM and ASR-920U-12SZ-IM Aggregation
Services Router Quick Start Guide
The Cisco ASR-920-12SZ-IM and Cisco ASR-920U-12SZ-IM are collectively referred to as the Cisco ASR-920-12SZ-IM
Router in this document. Any differences between the routers are specifically called out.
Note
The Cisco ASR 920 Series Aggregation Services Router is a family of fixed configuration routers that provides common network
architecture to the Service Providers for macro and small cell networks.
This router acts as an access device for mobile backhaul services—macro Cell Site Router (CSR) and Small Cell Router (SCR). As
an access device, it provides capabilities like 1GE/10GE, MPLS, H-QoS, Services, GPS clocking, PoE and fit within ETSI 300 mm
depth cabinet. It can easily be integrated into the Unified MPLS for Mobile Transport (UMMT) and Fixed Mobile Convergence
(FMC) solution.

This product requires surge protection as part of the building installation. To comply with the Telcordia GR-1089 NEBS
standard for electromagnetic compatibility and safety, an external surge protective device (SPD) is required at the AC power
service equipment.
Note
For DC systems, if a surge of more than 500 V is expected, add an appropriate external surge protective device.
Note
The routers support AC and DC power supplies in a 1+1 redundant configuration.
One AC and one DC power supply in the same router is also a supported configuration.
Note
The router has a single fan-tray with four fans. The system is designed to operate at its maximum operating temperature of 70º C, in
case of failure of a single fan operating temperature of 65º C. The fan tray is field-replaceable.
Licensing
The router supports the following types of licenses:
• Port Licensing—Port Upgrade license is available as a "Pay as you Grow" model.
• 6 ports 1GE upgrade license
• 2 ports 10G upgrade license
• Bulk License to enable 12x1port 1GE and 4x10GE ports

• Advanced Metro IP Access
• Metro IP Access
• Metro Access (default)
• Feature licensing
The following methods are used to activate the above licenses:
• Cisco Software Licensing—The Cisco Software License Activation feature is a set of processes and components to activate
Cisco software feature sets by obtaining and validating fee-based Cisco software licenses.
Licenses generated by the Cisco Software Licensing are tied to the UDI of the chassis and a corresponding watchtower device
certificate (WDC) is stored in the system.
Note
• Cisco Smart Licensing—Smart Licensing is usage-based licensing where devices register with the Cisco Secure server.
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
To attach the router on a 19-inch rack, use the 19-inch brackets (part number 700-39959-01).
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.
Note
For more information on brackets, see the Cisco ASR-920-12SZ-IM and ASR-920U-12SZ-IM Aggregation Services Router Hardware
Installation Guide.

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 in the Cisco ASR-920-12SZ-IM and ASR-920U-12SZ-IM
Aggregation Services Router Hardware Installation Guide.
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 Locate the mounting holes of the router.
Step 4 Align the rack-mounting bracket with the router and position with the four #6-32 x 0.25-inch screws (provided).
Step 5 Insert the screws (four places) and tighten using a Number 2 Phillips screwdriver (each side).
Step 6 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 7 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.
Note
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.
