(Optional) diskette drive activity LED
When this LED is lit, it indicates that the diskette drive is in use.
Hot-swap hard disk drive activity LED (some models)
On some server models, each hot-swap drive has a hard disk drive activity
LED. When this green LED is flashing, it indicates that the associated hard
disk drive is in use.
When the drive is removed, this LED also is visible on the hard disk drive
backplane, next to the drive connector. The backplane is the printed circuit
board behind drive bays 4 through 7 (or bays 4 through 11 on some
2.5-inch hard disk drive SAS models).
Hot-swap hard disk drive status LED (some models)
On some server models, each hot-swap hard disk drive has an amber
status LED. If this amber status LED for a drive is lit, it indicates that the
associated hard disk drive has failed.
If an optional IBM ServeRAID controller is installed in the server and the
LED flashes slowly (one flash per second), it indicates that the drive is
being rebuilt. When the LED is flashing rapidly (three flashes per second), it
indicates that the controller is identifying the drive.
When the drive is removed, this LED also is visible on the hard disk drive
backplane, below the hot-swap hard disk drive activity LED.
