• Power-control button: Press this button to turn the server on and off manually.
• Hard disk drive activity LEDs: This LED is used on hot-swap SAS or SATA hard disk drives. Each
hot-swap hard disk drive has an activity LED, and when this LED is flashing, it indicates that the drive is
in use.
• Hard disk drive status LEDs: This LED is used on hot-swap SAS or SATA hard disk drives. When this
LED is lit, it indicates that the drive has failed. If an optional ServeRAID adaptor is installed in the server,
when this LED is flashing 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.
• DVD drive activity LED: When this LED is lit, it indicates that the DVD drive is in use.
• DVD eject button: Press this button to release a DVD or CD from the DVD drive.
• Light path diagnostics panel: Light path diagnostics is a system of LEDs on various external and internal
components of the server. When an error occurs, LEDs are lit throughout the server. By viewing the LEDs
in a particular order, you can often identify the source of the error. See "Light path diagnostics panel"
on page 18 for more information about the light path diagnostics.
• Operator information panel: This panel contains controls and LEDs that provide information about the
status of the server. For information about the controls and LEDs on the operator information panel, see
"Operator information panel" on page 17.
