Note: The maximum video resolution is 1600 x 1200 at 75 Hz.
v Serial connector: Connect a 9-pin serial device to this connector. The serial port
is shared with the integrated management module (IMM). The IMM can take
control of the shared serial port to perform text console redirection and to
redirect serial traffic, using Serial over LAN (SOL).
v USB connectors: Connect a USB device, such as a USB mouse or keyboard to
any of these connectors.
v Systems-management Ethernet connector: Use this connector to connect the
server to a network for full systems-management information control.
v 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.
The following illustration shows the LEDs on the rear of the server.
The following illustration shows the LEDs on a dc power supply.
v 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.
v 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.
v AC power LED: Each hot-swap ac 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
