1G Copper and 1G SFP LED Indication
Management Port LED Indication
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.
Except for TDM IM, you can hot-swap an interface module with a similar interface module on Cisco
ASR-920-24SZ-IM Router. For more information, see
section on page 3-21.
