This section describes the controls and light-emitting diodes (LEDs) and how to turn
the server on and off.

Front view

The following illustration shows the controls, light-emitting diodes (LEDs), and
connectors on the front of the server.
Hard disk drive activity LED: Each hot-swap hard disk drive has an activity LED.
When this LED is flashing, it indicates that the drive is in use.
Hard disk drive status LED: 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.
Video connector: Connect a monitor to this connector. The video connectors on
the front and rear of the server can be used simultaneously.
USB connectors: Connect a USB device, such as USB mouse, keyboard, or other
USB device, to either of these connectors.
