  • Power connector: Connect the power cord to this connector.
  • AC power LED: This green LED provides status information about the power supply. During typical operation, both the ac and dc power LEDs are lit.
  • DC power LED: This green LED provides status information about the power supply. During typical operation, both the ac and dc power LEDs are lit.
  • Fault-error LED: When this yellow LED is lit, it indicates that the power supply has failed.
  • Serial connector: Connect a 9-pin serial device to this connector. The serial port is shared with the integrated management module II (IMM2). The IMM2 can take control of the shared serial port to redirect serial traffic, using Serial over LAN (SOL).
  • Video connector: Connect a monitor to this connector.
    Note
    When attaching a monitor to the equipment, you must use the designated monitor cable and any interference suppression devices supplied with the monitor.
  • USB connectors: Connect USB devices to these connectors.
  • NMI button: Press this button to force a nonmaskable interrupt to the microprocessor. It allows you to blue screen the server and take a memory dump (use this button only when directed by the IBM service support). You might have to use a pen or the end of a straightened paper clip to press the button.
  • Ethernet connectors: Use either of these connectors to connect the server to a network. When you use the Ethernet 0 connector, the network can be shared with the IMM2 through a single network cable.
  • Ethernet transmit/receive activity LED: This LED is on the Ethernet connector. When this LED is lit, it indicates that there is activity between the server and the network.
  • Ethernet link status LED: This LED is on the Ethernet connector. When this LED is lit, it indicates that there is an active connection on the Ethernet port.
