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	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

Caution

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
