Overview

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

Cisco ASR 920 Series Aggregation Services Router Configuration Guide

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

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.

Note

•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.

Caution

•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

products-installation-guides-list.html.

All variants of the Cisco ASR 920 Series Router have 8MB of NOR flash, and 4GB of DRAM.

•Interfaces 0–3 are GigabitEthernet SFP only ports.

•Interfaces 4–11 GigabitEthernet are combo ports that support dual media—Copper and SFP. For more

information, see the Configuring Auto Media Sense on Cisco ASR 920 Series Routers.

•Interfaces 0 through 11 are referred to as GigabitEthernet 0/0/0–GigabitEthernet 0/0/11 respectively

•Interfaces 12 and 13 are dual rate ports. These ports support 1G or 10G mode depending on the optics

(SFP or SFP+ respectively) installed in these ports.

Dual-Rate functionality is supported only with the Supported SFPs, listed in the Cisco ASR 920 Series

Aggregation Services Router Hardware Installation Guide .
