Power-cord connector:
Connect the power cord to this connector.
System-management Ethernet connector:
Use this connector to connect the server to a
network for systems-management information control. This connector is used only by
the integrated management module (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 MAX5 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.
