PCI-X slot attention LED: This green LED flashes approximately once per second when it is on. This LED is visible from the rear of the server and from inside the server. The meaning of the attention LED is defined by your operating system. For an illustration showing this LED on the system board, see the Option Installation Guide on the IBM xSeries Documentation CD. For additional information, see the “LEDs for Active PCI slots” in the Hardware Maintenance Manual and Troubleshooting Guide on the IBM xSeries Documentation CD.

NMI button: The Non-Maskable Interrupt (NMI) button is for service use only.

DC power LED: This green LED provides status information about the power supply. During typical operation, both the ac and dc power LEDs are on. For any other combination of LEDs, see the Hardware Maintenance Manual and Troubleshooting Guide on the IBM xSeries Documentation CD.

AC power LED: This green LED provides status information about the power supply. During typical operation, both the ac and dc power LEDs are on. For any other combination of LEDs, see the Hardware Maintenance Manual and Troubleshooting Guide on the IBM xSeries Documentation CD.

Important: If the power-on LED is off, it does not mean there is no electrical current present in the server. The LED might be burned out. To remove all electrical current from the server, you must unplug the server power cords from the electrical outlets or from the uninterruptible power device.

Power-on LED: When this green LED is on, power is present in the server. When this LED flashes, the server is in Standby mode (the system operating system is turned off and ac current is present). When this LED is off, the power subsystem, the ac power, or an LED has failed.

POST-complete LED: This green LED is on when POST is completed without any errors.

Hard disk drive activity LED: This green LED flickers when there is activity on a hard disk drive.

Information LED: When this amber LED is on, the server power supplies are nonredundant, or some other noncritical event has occurred. The event is recorded in the Error log. See “Choices available from the Configuration/Setup main menu” on page 16 for instructions for viewing the Error log. Check the diagnostic LED panel for more detailed information (see the Hardware Maintenance Manual and Troubleshooting Guide on the IBM xSeries Documentation CD).
