Hard disk drive activity LED: Each of the hot-swap drives has a hard disk drive
activity LED. When this green LED is flashing, the controller is accessing the drive.
Hard disk drive status LED: Each hot-swap drive has a hard disk drive status
LED. When this amber LED is lit continuously, the drive has failed. If a RAID
adapter is installed in the server, when the LED flashes slowly (one flash per
second), the drive is being rebuilt. When the LED flashes rapidly (three flashes per
second), the controller is identifying the drive.
Information LED: This amber LED is lit when the information log contains
information about certain conditions in your server that might affect performance.
For more information, see “Diagnostic panel LEDs” on page 32
System-identification LED: This blue LED is lit in response to a programmed
condition, or it can be turned on remotely by the system administrator to aid in
server identification for maintenance. The system administrator can turn off the
system identification LED after maintenance is complete.
