3-3

 HDD: Indicates IDE channel activity. On the Series3800/SR120-2 (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 Series3800/120R-2 (6025B-3

/6025B-3R) are not connected to a backplane. These may be used to house IDE

type hard drives only and are not hot-swappable.
