The following illustration shows the connectors on the
rear of the server.
Figure 1. Rear view connectors
- NMI button: Press this button to force a nonmaskable interrupt
to the microprocessor. It allows you to blue screen the server and
take a memory dump (use this button only when directed by the Lenovo
service support). You 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.
- PCI slot 1: Insert a low-profile PCI Express adapter into
this slot.
- PCI slot 2: Insert a half-length, full-height PCI Express
or PCI-X adapter into this slot.
- 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.
- 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.
- 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 (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 (default) connector.
