H.7 CONNECTORS
There are four types of connectors associated with the graphics card; an analog monitor
connector, digital monitor connector, adapter cable connectors and the card edge connector.
NOTE: The graphic card’s edge connector mates with a PCI slot connector on the
system board. This interface is described in chapter 4 of this guide.
H.7.1 ADAPTER CABLE CONNECTOR
A display or monitor cannot be attached directly to the graphics card. The graphics card includes
two connectors for attaching adapter cables that are used to attach the monitor(s).
