3-4 SCSI Drive Carrier LEDs

Each SCSI drive carrier has two LEDs.

 Green: When illuminated, the green LED on the front of the SCSI drive car-

rier 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: The SAF-TE compliant backplane activates the red LED to indicate a

drive failure. If one of the SCSI drives fail, you should be notiﬁ ed by your system

management software. Please refer to Chapter 6 for instructions on replacing failed

SCSI drives.
