Controls and Indicators

The most commonly used controls and indicators on the front of the server appear in the following illustration.

Door Lock (Tower Model Only): You can lock the door on the server to deter tampering with the internal components. This same lock also locks the top cover in place.

Power Control Button: Press this button to manually turn the server on or off.

The Power Control button on the front of the server does not turn off the electrical current supplied to the server. The server also might have more than one power cord. To remove all electrical current from the server, ensure that all power cords are disconnected from the power source.

The server can be activated in several ways:

You can turn the server on by pressing the Power Control button on the front of the server.
Note: If you have just plugged the power cord of the server into an electrical outlet, you will have to wait approximately 20 seconds before pressing the Power Control button.
If the server is activated and a power failure occurs, the server will start automatically.
The server can also be powered on by the system management processor.

The server can be deactivated as follows:

You can turn the server off by pressing the Power Control button on the front of the server. Pressing the Power Control button starts a graceful shutdown of the operating system, if this feature is supported by the operating system, and places the server in standby mode.
Note: After turning off the server, wait at least 5 seconds before pressing the Power Control button to power the server on again.
Pressing and holding the Power Control button for more than 4 seconds causes an immediate shutdown of the server and places the server in standby mode. This feature can be used if the operating system hangs.
Disconnecting the server power cords from the electrical outlets will shut off all power to the server.

Note: Wait about 15 seconds after disconnecting the power cord for the system to stop running. Watch for the System Power light on the information LED panel to stop blinking.

Reset Button: Press this button to reset the system and run the power-on self-test (POST).
Information LED Panel: The lights on this panel give status information for the server. See 'Information LED Panel' for more information.
Diskette-Eject Button: Press this button to eject a diskette from the drive.
CD-ROM Eject/Load Button: Press this button to eject or retract the CD-ROM tray so that you can insert or remove a CD.
CD-ROM Drive In-Use Light: When this light is lit, the CD-ROM drive is being accessed.
Diskette Drive In-Use Light: When this light is lit, the diskette drive is being accessed.
Hard Disk Lights: Each of the six hot-swap drive bays has a set of two lights, which indicate the following:

Hard Disk Status Light: When the amber light for a hard disk drive is lit continuously, the drive has failed. When the light flashes slowly (one flash per second), the drive is being rebuilt.
When the light flashes rapidly (three flashes per second), the controller is identifying the drive.
Hard Disk Activity Light: When the green light for a hard disk drive is flashing, the drive is being accessed.
