This LED and LEDs on the light path diagnostics panel remain lit until you resolve the condition. If the only condition is that the BMC log is full or almost full, clear the BMC log or the system-event log through the Configuration/Setup Utility program to turn off the lit LEDs. See “Using the Configuration/Setup Utility program” on page 58 for information about clearing the logs. Clear the logs after you have resolved all conditions.

Important: If the server has a baseboard management controller, clear the BMC log and system-event log after you resolve all conditions. This will turn off the information LED and LOG LED, if all conditions are resolved.

vRelease latch: Slide this latch to the left to access the light path diagnostics panel.

vSystem-error LED: When this LED is lit, it indicates that a system error has occurred. An LED on the light path diagnostics panel is also lit to help isolate the error.

vLocator LED: When this LED is lit, it has been lit remotely by the system administrator to aid in visually locating the server.

In multi-node configurations, when this LED flashes during startup, it indicates that the server is the primary node. When this LED is lit during startup, it indicates that the server is a secondary node.

vHard disk drive activity LED: When this LED is flashing, it indicates that a SAS hard disk drive is in use.

vPower-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.

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 cords from the electrical outlets.

Electrostatic-discharge connector: Connect an electrostatic-discharge wrist strap to this connector.

DVD drive activity LED: (Standard on some models only) When this LED is lit, it indicates that the DVD drive is in use.

DVD-eject button: (Standard on some models only) Press this button to release a CD or DVD from the DVD drive.
