When the ac power LED is lit, it indicates that sufficient power iscoming 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, seethe Problem Determination and Service Guide on the IBM System xDocumentation CD.v DC power LED: Each hot-swap power supply has a dc power LED and an acpower LED. When the dc power LED is lit, it indicates that the power supply issupplying adequate dc power to the system. During typical operation, both the acand dc power LEDs are lit. For any other combination of LEDs, see the ProblemDetermination and Service Guide on the IBM System x Documentation CD.v System-error LED: When this LED is lit, it indicates that a system error hasoccurred. An LED on the light path diagnostics panel is also lit to help isolate theerror.v Power-on LED: When this LED is lit and not flashing, it indicates that the serveris turned on. When this LED is flashing, it indicates that the server is turned offand still connected to an ac power source. When this LED is off, it indicates thatac power is not present, or the power supply or the LED itself has failed.v System-locator LED: Use this LED to visually locate the server among otherservers. You can use IBM Director to light this LED remotely.v Video connector: Connect a monitor to this connector. The video connectors onthe front and rear of the server can be used simultaneously.v Serial connector: Connect a 9-pin serial device to this connector. The serial portis shared with the baseboard management controller (BMC). The BMC can takecontrol of the shared serial port to perform text console redirection and to redirectserial traffic, using Serial over LAN (SOL).v USB connectors: Connect a USB device, such as a USB mouse, keyboard, orother device to any of these connectors.v Systems-management Ethernet connector: Use this connector to connect theserver to a network for systems-management information control. This connectoris active only if you have installed an optional Remote Supervisor Adapter IISlimLine, and it is used only by the Remote Supervisor Adapter II SlimLine.Chapter 1.
