Replace the SSB
The SSB is hot-pluggable. When the SSB is removed, all packet forwarding stops
immediately and the Routing Engine responds by sending alarms through the Ethernet
channel to the management console. When the SSB is replaced, it is rebooted by flash
EEPROM.
If the SSB fails, replace it as described in the M20 Internet Router Hardware Guide.
