Cisco ASR 920 family of routers include:
• ASR 920-I (Indoor) [ASR-920-12CZ-A/ASR-920-12CZ-D]—This sub-family has fixed ENET interfaces
(12 x 1 GE + 2 x 10GE) and dual power supplies (AC/DC).
• ASR 920-C (Compact) [ASR-920-4SZ-A/ASR-920-4SZ-D]—This sub-family of routers have a compact
form factor and configurable ports: 4 x 1 GE or 4 x 10 GE or any combinations of 1 GE and 10 GE
among the four ports available. In addition, there are 2 x 1 GE copper ports available.
• ASR 920-O (Outdoor) [ASR-920-10SZ-PD]—This sub-family is designed for deployment outdoors in
an environment protected from rain and direct sunlight and provides cost optimized, and extended
temperature range for business, residential, and mobile access services.
• ASR 920-F (Fixed) [ASR-920-24SZ-M/ASR-920-24TZ-M]—This sub-family with 1 RU form factor
has fixed ENET interfaces (four 10GE and twenty-four 1GE Copper or SFP) and redundant modular
power supplies (AC/DC).
• ASR 920-M (Modular) [ASR-920-24SZ-IM]—This sub-family with 1.5 RU form factor has fixed ENET
interfaces (four 10GE and twenty-four 1GE Fiber), one modular interface and redundant modular power
supplies (AC/DC). The interface modules from ASR 900 family of routers can be leveraged for use with
this model.
• ASR-920-12SZ-IM—Eight 1G copper ports, four SFP ports, and four 1G/10G Dual Rate ports one IM
slot Power over Ethernet (PoE), and a global navigation satellite system (GNSS) port, with redundant
AC or DC power supplies

Overview
Getting Started With the Cisco ASR 920 Series Router
In addition to the 1G/10G interfaces, the Cisco ASR 920 Series Routers also have the following hardware
interfaces for management, and timing and synchronization features:
One Copper 10/100/1000Base-T LAN management port
•
One BITS interface with RJ48 Connector
•
One 1PPS or Time of Day port with RJ45 interface
•
External Alarm interface with 4 Dry Contact Alarm inputs
•
One RS-232 Console Port with USB A type connector
•
Note
Caution
Due to the USB form factor, the flow control pins are not connected and the terminal server hosting the
RS232 session must configure no flow-control or the console access to work correctly.
One USB2.0 Console Port
•
One USB2.0 Port for Mass Storage
•
ZTP button for Zero Touch Provisioning
•
A short press of the ZTP button starts the provisioning of the router. Pressing this button for 8 seconds or
more leads to Powering off the System Power.
Various LEDs for system and interface status
•
The Cisco ASR-920-12SZ-IM Router also supports:
•
Power over Ethernet (PoE) port
◦
Global navigation satellite system (GNSS) port
◦
