Power-cord connector: Connect the power cord to this connector.
System-management connector: Use this connector to connect the server to a
network for systems-management information control. This connector is used only
by the IMM.
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).
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 MAX5 memory expansion module to
your server. See the documentation that came with your QPI cable kit for detailed
cabling instructions.
Gigabit Ethernet 1 and 2 connectors: Use these connectors to connect the server
to a network.
