might have to use a pen or the end of a straightened paper clip to press the
button. The NMI button is in the lower left-hand corner on the rear of the
server.
v Power connector: Connect the power cord to this connector.
Note: Power supply 1 is the default/primary power supply. If power supply 1
fails, you must replace it immediately.
v Video connector: Connect a monitor to this connector. The video connectors on
the front and rear of the server can be used simultaneously.
Note: The maximum video resolution is 1600 x 1200 at 75 Hz.
v Eight Universal Serial Bus (USB) connectors: Connect a USB device, such as a
USB mouse or keyboard to any of these connectors. Eight Universal Serial Bus
provides 2.0 and 3.0 ports.
v 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 IMM2.1. 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. See Using the Setup utility in the Problem Determination and Service
Guide for more information.
v 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.
v Serial connector (optional): Connect a 9-pin serial device to this connector. The
serial port is shared with the integrated management module II (IMM2.1). The
IMM2.1 can take control of the shared serial port to redirect serial traffic, using
Serial over LAN (SOL).
The following illustration shows the LEDs on the rear of the server.
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.
