C H A P T E R Overview The Cisco ASR-920-20SZ-M Router is a fixed configuration router that enables Service Providers to provide business, residential, and mobile access services to their users. It is the Carrier Ethernet access platform providing Ethernet services.
Overview GigabitEthernet Copper Ports Figure 1: Cisco ASR-920-20SZ-M Top and Front Panel The following table provides a snapshot of the number and type of supported ports: Table 1: Supported Ports on Cisco ASR-920-20SZ-M Router ASR 920 Sub-family 1 GE Port...
• Pause flow control as defined by the 802.3x standard. • Frame size of 9216 bytes. External Interfaces The Cisco ASR 920-20SZ-M Router has these external physical interfaces on the front panel: Network Interfaces The network interfaces are provided through fixed ports.
A single USB 2.0 Type-A receptacle on the front panel of the router provides console access to ROMMON, Cisco IOS-XR and diagnostics. While it uses the Type-A connector, it operates as a USB peripheral only for connection to an external host computer. This interface requires the use of a Type-A to Type-A connector instead of a standard USB cable.
For DC systems, if a surge of more than 1KV is expected, add an appropriate external surge protective device. The Cisco ASR-920-20SZ-M Router has six fixed fans as a part of the system. The system is designed to operate at its maximum operating temperature of 70ºC and at an altitude of 300 meters. If a single fan fails, the system runs at a maximum operating temperature of 65ºC.
Note 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. • Cisco Smart Licensing—Smart Licensing is usage-based licensing where devices register with the Cisco Secure server.
