3-3
Power Fail: Indicates a power supply module has failed. This LED is inended
for use with systems that have redundant power supply modules and therefore is
not used with the SuperWorkstation 7045A-3.
3-4 SAS Drive Carrier LEDs
Each SAS drive carrier has two LEDs.
Green: When illuminated, the green LED on the front of the SAS drive carrier
indicates drive activity. A connection to the SAS SCA backplane enables this LED
to blink on and off when that particular drive is being accessed.
Red: A SAF-TE compliant backplane is needed to activate the red LEDs,
which indicate a drive failure. Please refer to Chapter 6 for instructions on replacing
failed SAS drives.
