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 Ethernet activity LEDs: When these LEDs are lit, they indicate that there is activity between the server
and the network.
v Power cord connector: Connect the power cord to this connector.
v Video connector: Connect a monitor to this connector. The video connectors on the rear of the server
can be used simultaneously.
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 redirect
serial traffic, using Serial over LAN (SOL).
USB connectors: Connect a USB device, such as a USB mouse, keyboard, or other device to any of
v
these connectors.
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.
v NMI button: Press this button to force a nonmaskable interrupt to the microprocessor. You might have
to use a pen or the end of a straightened paper clip to press the button. It allows you to blue screen
the server and take a memory dump (use this button only when directed by the Lenovo service
support).
v PCI slot 1: A low-profile PCI Express or PCI-X card can be installed into this slot. Standard models of
the server come with a PCI Express riser assembly. You can purchase an optional PCI-X riser-card
assembly with bracket if you want to install a PCI-X card in this slot.
v PCI slot 2: A half-length, full-height PCI Express or PCI-X card can be installed into this slot. Standard
models of the server come with a PCI Express riser assembly. You can purchase an optional PCI-X
riser-card assembly with bracket if you want to install a PCI-X card in this slot.
