AC power LED: Each hot-swap power supply has an ac power LED and a dc power LED. When the ac power LED is lit, it indicates that sufficient power is coming into the power supply through the power cord. During typical operation, both the ac and dc power LEDs are lit. For any other combination of LEDs, see the Problem Determination and Service Guide on the IBM Documentation CD. DC power LED: Each hot-swap power supply has a dc power LED and an ac power LED. When the dc power LED is lit, it indicates that the power supply is supplying adequate dc power to the system. During typical operation, both the ac and dc power LEDs are lit. For any other combination of LEDs, see the Problem Determination and Service Guide on the IBM Documentation CD. Power-supply error LED: When the power-supply error LED is lit, it indicates that the power supply has failed. Note: Power supply 1 is the default/primary power supply. If power supply 1 fails, you must replace the power supply immediately. System-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. This LED is the same as the system-error LED on the front of the server. Locator LED: Use this LED to visually locate the server among other servers. You can use IBM Systems Director to light this LED remotely. This LED is the same as the system-locator LED on the front of the server. Power-on LED: Press this button to turn the server on and off manually or to wake the server from a reduced-power state. The states of the power-on LED are as follows: Off: AC power is not present, or the power supply or the LED itself has failed. Flashing rapidly (4 times per second): The server is turned off and is not ready to be turned on. The power-control button is disabled. Approximately 3 minutes after the server is connected to ac power, the power-control button becomes active. Flashing slowly (once per second): The server is turned off and is ready to be turned on. You can press the power-control button to turn on the server. Lit: The server is turned on. Fading on and off: The server is in a reduced-power state. To wake the server, press the power-control button or use the IMM Web interface. For information about logging on to the IMM Web interface, see "Logging on to the Web interface" on page 125. 18 System x3650 M2 Type 7947: Installation and User's Guide
