Note: The maximum video resolution is 1600 x 1200 at 75 Hz.
Systems-management Ethernet connector: Use this connector to connect the
server to a network for systems-management information control. This connector is
used only by the IMM.
The following illustration shows the LEDs on the rear of the server.

Ethernet activity LEDs: When any of these LEDs is lit, it indicates that the server
is transmitting to or receiving signals from the Ethernet LAN that is connected to the
Ethernet port that corresponds to that LED.
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 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 69.
IN OK power LED: Each hot-swap dc power supply has an IN OK power LED and
an OUT 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 typical
operation, both the IN OK and OUT OK power LEDs are lit. For any other
combination of LEDs, see "Power-supply LEDs" on page 69.
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 69.
OUT OK power LED: Each hot-swap dc power supply has an IN OK power LED
and an OUT OK power LED. When the OUT OK power LED is lit, it indicates that
the power supply is supplying adequate dc power to the system. During typical
operation, both the IN OK and OUT OK power LEDs are lit. For any other
combination of LEDs, see "Power-supply LEDs" on page 69.
Power-supply error LED: When the power-supply error LED is lit, it indicates that
the power supply has failed.
Note: Power supply 1 is the default/primary power supply. If power supply 1 fails,
you must replace the power supply immediately.
