• Ethernet connectors: Use either of these connectors to connect the server to a network. When you
enable shared Ethernet for IMM2.1 in the Setup Utility, you can access the IMM2.1 using either the
Ethernet 1 or the system-management Ethernet (default) connector. See Using the Setup Utility for more
information.
• Serial connector (optional): Connect a 9-pin serial device to this connector. The serial port is shared with
the IMM2.1. The IMM2.1 can take control of the shared serial port to redirect serial traffic, using Serial
over LAN (SOL).

• 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.
• 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.
• AC power LED: Each hot-swap ac power supply has an ac 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, the ac power LED is lit. For any other combination of LEDs, see "AC power-supply LEDs" on
page 73.
• DC power LED: Each hot-swap ac power supply has a dc 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 "DC power-supply LEDs"
on page 74.
• IN OK power LED: Each hot-swap dc power supply has an IN OK power LED. When the IN OK power
LED is lit, it indicates that sufficient power is coming into the power supply through the power cord. During
