Checking the Indications by LEDs

This section describes the indications by LEDs on the SPARC M12-1.
LEDs are mounted on the operation panel on the front of the SPARC M12-1, on the
rear panel of the SPARC M12-1, and on those components that can be maintained. If
an error occurs, the LED indication enables you to determine the system that requires
maintenance.

Operation Panel LEDs

The three LEDs on the operation panel indicate the operation status of the entire
system. In addition, the LEDs enable you to check the system status by their
combination of being on, blinking, or off. For the locations of the LEDs, see
