Measures reported by IBMChassFrntLEDTest
The BladeCenter chassis contains the following LEDs in the front panel LED system:
Power-on: This green LED is lit indicating that the BladeCenter chassis is powered on. This LED is turned off when the power subsystem, the ac power or the LED is failed, or the management module is unavailable or not functioning properly, or the media tray is not fully seated.
Attention: If the power-on LED is off, it does not mean that the BladeCenter chassis has no power supply. The LED might be burned out. To remove all electrical current from the BladeCenter unit, you must disconnect all power cords from the BladeCenter unit.
Location: When this blue LED is lit or flashing, it has been turned on by the system administrator to aid in visually locating the BladeCenter unit. If a blade server requires attention, the location LED on the blade server usually will also be lit. After the BladeCenter unit has been located, you can have the system administrator turn off the location LED.
Over-temperature : When this amber LED is lit, the temperature in the BladeCenter unit exceeds the temperature limits, or a blade server reports an over-temperature condition. The BladeCenter unit might have already taken corrective action, such as increasing the blower speed. This LED turns off automatically when there is no longer an over-temperature condition.
Information: When this amber LED is lit, a noncritical event has occurred that requires attention, such as the wrong I/O module inserted in a bay or power demands that exceed the capacity of power modules that are currently installed. The event is recorded in the event log. Check the LEDs on the BladeCenter unit and the blade servers to isolate the component. After the situation is corrected, have the system administrator turn off the information LED.
System-error: When this amber LED is lit, it indicates that a system error has occurred, such as a failed module or a system error in a blade server. An LED on one of the components or on a blade server is also lit to further isolate the error.
Optical drive activity LED: When this LED is lit, it indicates that the optical drive is in use.
Tracking the status of these LEDs, administrators can find out the power status, errors, temperature, etc. of the target chassis at a single glance. This can be easily done using the FrontPanel LED test!
This test monitors the LEDs on the front panel of the chassis and reports the current status of temperature LED and error LED.
Outputs of the test : One set of results for the BladeCenter chassis being monitored.
