Rear View Leds - IBM X3950 X5 Problem Determination And Service Manual

System-management Ethernet connector: Use this connector to connect the server
integrated management module (IMM) to a network. The IMM is used for
systems-management and information control. This connector is used only by the
IMM.
QPI ports 1 - 4: In a single-node configuration, use these connectors to insert either
a QPI wrap card or a filler panel. The QPI wrap cards enable increased
performance in certain models. In a two-node configuration, insert the QPI cables
in these ports to connect another server or a memory expansion module to your
server. See the documentation that came with your QPI cable kit for detailed
cabling instructions.
USB connectors: Connect USB devices, such as a USB mouse or keyboard, to these
connectors.
Video connector: Connect a monitor to this connector. In a two-node configuration,
connect the monitor to the primary server to see standard system output.
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 perform text console redirection and to redirect serial
traffic, using Serial over LAN (SOL).
Gigabit Ethernet 1 and 2 connectors: Use these connectors to connect the server to
a network.
