Hard disk drive activity LED

When this LED is flashing, it indicates that the associated hard disk drive

is in use.

System-error LED

When this amber LED is lit, it indicates that a system error has occurred.

An LED on the system board might also be lit to help isolate the error. See

Chapter 5, “Solving problems,” on page 51 for additional information.

Detailed troubleshooting information is in the Hardware Maintenance

Manual.

Note:

When a PCI Express error LED and the system-error LED is lit, it

indicates that a PCI Express error has occurred. The system-error

LED will turn off when you reboot the server. When a DIMM error

LED and the system-error LED is lit, it indicates that a DIMM error

has occurred. After you correct the DIMM error, the DIMM error

LED and the system-error LED will turn off.

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 RAID 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.
