Notes:

1.The illustrations in this document might differ slightly from your hardware.

2.An amber LED illuminates when a system error or event has occurred. To identify the error or event, check the LEDs on the Light Path Diagnostics panel located on the server, or review the Error Log in the Configuration/Setup Utility program. For complete details about the Light Path Diagnostics panel, see the Hardware Maintenance Manual and Troubleshooting Guide on the IBM xSeries Documentation CD. For more information about the Configuration/Setup Utility program, see “Choices available from the Configuration/Setup Utility main menu” on page 14.

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

Power-control button: Press this button to manually turn the server on or off or to place the server in Standby mode (see “Standby mode” on page 12).
