The following illustration shows the connectors and LEDs on the rear of the server.
Attention:
the dc power supply for information about the power-supply LEDs.
Power-cord
connector
Power-cord connector (ac power supply only): Connect the power cord to this
connector.
Attention:
IBM service technicians are authorized to connect or disconnect power to the dc
power supply. See the documentation that comes with each dc power supply.
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 System x 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 System x Documentation CD.
Systems-management Ethernet connector: Use this connector to connect the
server to a network for systems-management information control. This connector is
active only if you have installed a Remote Supervisor Adapter II SlimLine, and it is
used only by the Remote Supervisor Adapter II SlimLine.
Ethernet activity LEDs: When these LEDs are lit, they indicate that the server is
transmitting to or receiving signals from the Ethernet LAN that is connected to the
Ethernet port.
