Hard Drive LEDs Status

Hard disk drive activity LED (front panel): When this LED is flashing, it indicates that the drive is in use. This function is reserved for simple-swap models. For existing models, please see the hot-swap hard disk drive activity and status LEDs (green and amber) that pass from the backplane as the indicators for any activity or warning.
Hard disk drive status LED (amber): This amber LED is used on hot-swap SAS/SATA hard disk drives. Each hot-swap hard disk drive has a status LED. When this LED is lit, it indicates that the drive has failed. When this LED is flashing slowly (one flash per second), it indicates that the drive is being rebuilt as part of a RAID configuration. When the LED is flashing rapidly (three flashes per second), it indicates that the controller is identifying the drive.
