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

v PCI slot 1: Insert a low-profile PCI Express adapter into this slot.
v PCI slot 2: Insert a half-length, full-height PCI Express or PCI-X adapter into
this slot.
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 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).
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. This
connector is used only by the integrated management module (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.
v 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 (default) connector.
