CD or DVD drive activity LED When this LED is lit, it indicates that the CD drive or DVD drive is in use. (Optional) Diskette-eject button Press this button to release a diskette from the diskette drive. (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 SAS 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 (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 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 backplane, below the hot-swap hard disk drive activity LED. 34 xSeries 206m Types 8485 and 8490: Installation Guide
