Use a 4-pin cable to connect a device to a USB connector. If you need to connect
more USB devices than the server has USB connectors for, use a USB hub to
connect additional devices.
If you connect a PS/2 (non-USB) keyboard to the keyboard connector, USB ports
and devices are disabled during POST.
If you connect a USB keyboard that has a mouse port, the keyboard emulates a
mouse, and you cannot disable the mouse settings in the Configuration/Setup Utility
program.
Video connector
The super video graphics array (SVGA) video adapter is installed in mini-PCI slot 6
on the system board. There is one video connector on the rear of the server. Use
the video connector to connect a monitor or other display. The following illustration
shows an industry-standard 15-pin analog video connector on the rear of the server.
