SCSI Drive Carrier LEDs

Each SCSI drive carrier has two LEDs.
!
Green: When illuminated, the green LED on the front of a SCSI drive
carrier indicates drive activity. A connection to the SCSI SCA backplane enables
this LED to blink on and off when that particular drive is being accessed.
!
Red: A SAF-TE compliant backplane (standard on the 6013P-8+) activates
the red LED, which indicates a drive failure. If one of the SCSI drives fail, you
should be notified by your system management software. Please refer to Chap-
ter 6 for instructions on replacing failed SCSI drives.
