AC and DC power LED: Each hot-swap power supply has an ac power LED and a dc power LED. During typical operation, both the ac and dc power LEDs are lit. For any other combination of LEDs, see the Hardware Maintenance Manual and Troubleshooting Guide on the IBM xSeries Documentation CD.

Hard disk drive activity LED: This green LED is lit when the hard disk drive is in use.

Hard disk drive status LED: When the drive is connected to the integrated SCSI controller with RAID capabilities, a flashing status LED indicates that the drive is a secondary drive in a mirrored pair and the drive is being synchronized. When the drive is connected to an optional ServeRAID controller, a slowly flashing (one flash per second) status LED 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.

USB port: Use this automatically configured port to connect one or more USB devices to the front of the server, using Plug and Play technology.

System-error LED: This amber LED is lit when a system error has occurred.

Information LED: This amber LED is lit when information about a system error has been placed in the System Error log.
