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
“Power-supply LEDs” on page 18.
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 “Power-supply
LEDs” on page 18.
Power error LED: When the power error LED is lit, it indicates that the power
supply has failed.
Power-cord connector: Connect the power cord to this connector.
Ethernet connectors: Use either of these connectors to connect the server to a
network. When you use the Ethernet 1 connector, the network can be shared with
the IMM through a single network cable.
Ethernet transmit/receive activity LED: This LED is on the Ethernet connector on
the rear of the server. When this LED is lit, it indicates that there is activity between
the server and the network.
