HDD: Indicates IDE channel activity. On the SuperServer 6025B-TR+/6025B-
8R+, this LED indicates SAS and/or DVD-ROM drive activity when fl ashing.
Power:
Indicates power is being supplied to the system's power supply
module(s). This LED should normally be illuminated when the system is operat-
ing.
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 car-
rier indicates drive activity. A connection to the SAS backplane enables this LED
to blink on and off when that particular drive is being accessed.
Red: The red LED indicates two states. When blinking, it indicates the drive
is rebuilding. When solid, it indicates a drive failure. If a SAS drive fails, you should
be notifi ed by your system management software. Please refer to Chapter 6 for
instructions on replacing failed SAS drives.
Note: the two drive bays on the top left of the 6025B-3/6025B-3R are not con-
nected to a backplane. These may be used to house IDE type hard drives only
and are not hot-swappable.
