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