Video port

The server comes with an integrated super video graphics
array (SVGA) video controller. This controller is not remov-
able, 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 following table shows the pin-number assignments for
the 15-pin analog video connector on the rear of the server.
