Cisco ASR 920 Router Features
Online Insertion and Removal
The Cisco ASR 920 router supports the following OIR operations:
• When an SFP is removed, there is no effect on traffic flowing on other ports.
• When an SFP is installed, the system initializes that port for operation based upon the current
configuration. If the inserted SFP is incompatible with the current configuration for that port, the
port does not become operational until the configuration is updated.
• Both power supplies are installed and active and the load may be shared between them or a single
PSU could support the whole load. When a power supply is not working or the input cable is
removed, the remaining power supply takes the entire load without disruption. If the power supply
needs repair, the whole system must be replaced.
Licensing the Cisco ASR 920 Router
The Cisco ASR 920 Series Routers support the following types of licenses:
• Port Licensing—Port Upgrade license is available as a "Pay as you Grow" model.
– 1G upgrade license

• Bulk licensing—Bulk port licensing allows you to enable all the ports with a single license.
• Timing license (1588)—Timing license is required if the router is used as a master clock.
• Advanced Metro IP Access
• Metro IP Access

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.
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.
