1. shut down the computer, unplug its power cord, and remove the chassis cover.

    2. insert the contact edge of the dge-550t card into the connector of any available pci bus master expansion slot. press the card firmly into the connector such that the card's contacts are fully seated in the connector.

    3. install the bracket screw that secures the card to the computer chassis.

    4. replace the computer's chassis cover.

    5. reconnect the computer's power cord, and switch computer power on. if the bios section of your computer's boot program is plug-and-play compliant, then at power-up the bios will automatically configure any newly installed dge-550t adapter.

    due to a fault in some plug-n-play bios programs, it happens occasionally that a newly installed adapter is assigned an interrupt number which is already assigned to another device. in such a case, the conflict of interrupt number will cause faults in the behavior of both devices. then it is necessary to run the cmos setup utility, and manually assign a non-conflicting interrupt number.
