LED Summary
The following sections describe the meanings of the LEDs on the Cisco ASR 907 Router.
RSP LEDs
The table below summarizes the RSP LEDs.
A major alarm condition indicates the failure of a single fan in the fan tray; a critical alarm indicates the failure
of multiple fans. In the event that a single fan fails, the Cisco ASR 907 Router software adjusts the fan speed
to prevent excessive heat within the chassis.
