• Ethernet link LEDs: When these LEDs are lit, they indicate that there is an active link connection on the
10BASE-T, 100BASE-TX, or 1000BASE-TX interface for the Ethernet port.
• Ethernet activity LEDs: When these LEDs are lit, they indicate that there is activity between the server
and the network.
• 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. For any other combination of LEDs, see “Power-supply
LEDs” on page 119.
• 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. For any other combination of LEDs, see “Power-supply

• Power supply error LED: When this yellow LED is lit, it indicates that the power supply has failed.
• Power cord connector: Connect the power cord to this connector.
• Video connector: Connect a monitor to this connector.
• 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).
• USB connectors: Connect a USB device, such as a USB mouse, keyboard, or other device to any of
these connectors.
• 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 IMM2 through a single network cable.
