3-3

 HDD: Indicates hard drive activity. On the AS1010P-8(R)/1010P-T(R) this

light indicates SCSI and/or DVD-ROM drive activity when ﬂ ashing.

 Power: Indicates power is being supplied to the system's power supply

module(s). With the 1010P-8/1010P-T, this LED should always be green when the

system is operating. On the 1010P-8R/1010P-TR, this LED turns amber in the event

of a power supply failure or if a power supply cord is disconnected or loose.

3-4 SCSI/SATA Drive Carrier LEDs

1010P-8/1010P-8R: 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.

1010P-T/1010P-TR: Each Serial ATA drive carrier has a green LED. When illumi-

nated, this green LED (on the front of the Serial ATA drive carrier) indicates drive

activity. A connection to the Serial ATA backplane enables this LED to blink on

and off when that particular drive is being accessed. Please refer to Chapter 6

for instructions on replacing failed SATA drives.

Note: The second LED on the SATA carriers is not used.
