4.2.3AM-987 to AM-174 34-Pin X-bus Cabling Instructions
AM-987 and Roadrunner boards are linked together with two 34-pin cables included in
the installation kit. These two cables make up the data path between the AM-987 and
Roadrunner boards. The cable connections must be made pin-1 to pin-1. To install the
cables, use the instructions in the illustration on the next page.
Take every precaution to plug the X-Bus cables in correctly. If the cables are not
plugged in correctly, the system will not boot or run self-test and the AM-174
board could be seriously damaged! If your computer does not boot after doing the
upgrade, turn off the power and double check your cable connections.
