•
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 or keyboard to any of these connectors.
•
Systems-management Ethernet connector:
Use this connector to connect the server to a network for
full systems-management information control. This connector is used only by the Integrated Management
Module II (IMM2). A dedicated management network provides additional security by physically separating
the management network traffic from the production network. You can use the Setup utility to configure
the server to use a dedicated systems management network or a shared network.
•
Ethernet connectors:
Use either of these connectors to connect the server to a network. When you
enable shared Ethernet for IMM2 in the Setup utility, you can access the IMM2 using either the Ethernet 1
or the system-management Ethernet connector.
The following illustration shows the LEDs on the rear of the server.

•
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 Ethernet port.
•
AC power LED:
Each hot-swap 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.
•
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.
•
Power-supply error LED:
When the power-supply error LED is lit, it indicates that the power supply
has failed.
