External Standard Control Panel Connectors

The standard control panel has two external I/O connectors:
•
One USB port
•
One VGA video port
The following tables provide the pin-outs for each connector.
If a monitor is connected to the control panel video connector, the rear video port on the server
board will be disabled and the control panel video will be enabled. The video source is the
same for both connectors and is switched between the two, with the control panel having priority
over the rear video. This provides for easy front accessibility to the server.
