Server controls, LEDs, and power 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, LEDs, and connectors on the front of the server. CD-eject button CD drive activity LED Hard disk drive activity LEDs Power-on LED Power-control button Hard disk drive status LEDs USB 1 connector USB 2 connector Operator information panel Reset button CD drive activity LED: When this LED is lit, it indicates that the CD drive is in use. CD-eject button: Press this button to release a CD from the CD drive. Hard disk drive activity LEDs: When one of these LEDs is flashing, it indicates that the associated SCSI hard disk drive is in use. Power-on LED: When this LED is lit and not flashing, it indicates that the server is turned on. When this LED is flashing, it indicates that the server is turned off and still connected to an ac power source. When this LED is off, it indicates that ac power is not present, or the power supply or the LED itself has failed. A power-on LED is also on the rear of the server. Note: If this LED is off, it does not mean that there is no electrical power in the server. The LED might be burned out. To remove all electrical power from the server, you must disconnect the power cord from the electrical outlet. Power-control button: Press this button to turn the server on and off manually. Reset button: Press this button to reset the server and run the power-on self-test (POST). You might have to use a pen or the end of a straightened paper clip to press the button. Operator information panel: This panel contains LEDs. The following illustration shows the LEDs on the operator information panel.
