Video port
Your server comes with an integrated super video graphics array (SVGA) video
controller. This controller is not removable, but you can disable it by installing a PCI
video adapter.
Note: If you install a PCI video adapter, the server BIOS will automatically disable
the integrated video controller.
The integrated video controller is located on PCI bus A (slot 1) on the system
board. See “Adapter considerations” on page 51 for detailed information about the
PCI buses in your server.

Keyboard port
There is one keyboard port on the rear of your server.
Note: If you attach a standard (non-USB) keyboard to the keyboard port, the USB

might need to use the Configuration/Setup Utility to Enable keyboardless
operation and prevent the POST error message 301 from being displayed
during startup. For detailed information about this option and how to connect
it to your server, refer to the documentation that comes with the option.
