Chapter 3: System Interface

HDD: Indicates IDE channel activity. On the SuperServer 6025B-TR+/6025B- 8R+, this LED indicates SAS and/or DVD-ROM drive activity when flashing.

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 notified 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.
