Many motherboards today have a variety of additional connectors for different types of ports that do not fit on the motherboards ATX connector plate. TO handle these, they supply additional headers that connect to the motherboard and reside in a card slot cover. Additionally, some of these connectors may reside on the case and can be connected into the motherboard.
The installation of any header is very similar to that of installing a standard interface card. Please refer to the Installing a PCI Card guide for information on how to do this.
Once the header has been installed into a card slot, this and any case port connectors need to be attached to the motherboard. Please consult the motherboard manual for the appropriate location of the connectors on pin layouts on the motherboard for these cables.
It is still necessary at this point to install the remaining adapter cards and drives to the motherboard in order to complete the system installation. It is important that once the system is up and running to verify that all the connectors, jumpers and switches are properly installed. If any of them are not work, power down the system and refer to the instruction manual to see if the connectors may be improperly installed.
