The status and control panel includes two LED indicators and a three-position security keyswitch.
The front panel keyswitch controls the power-on modes of the system. The following table describes the function of each switch setting.

Power-On/Off |
This setting enables the system's Power button to turn the system power on or power off. If the system has power, holding the Power button down for five seconds while the keyswitch is in this position will cause an immediate hardware power off. |
|
Locked |
This setting disables the system's Power button, and also locks the front doors preventing access to the disk drives and to the power supplies. The Locked position is the recommended setting for normal day-to-day operation of the system. |
|
Standby |
This setting places the system in Standby mode by turning off power to all internal system components and by placing the power supplies in Standby mode. When the keyswitch is in this position, the keyboard power switch and the server's Power button are disabled. |
The two system LEDs consist of a system health indicator and a fault indicator. The system health indicator lights continuously green to show that the system is functioning normally. The fault indicator lights when a problem is detected in the system. Because it is important to know that a fault exists in the system, the fault indicator remains lit whether the system is in normal operating mode, or is switched to Standby mode using the keyswitch.
When you first power on the system, the LEDs individually blink on and off to verify that each one is working correctly. After that, the LEDs operate as described in the following table.
