Dear Engineer,
Custom, PCI, CompactPCI, VMEbus, and AdvancedTCA backplanes have a lot in common, particularly when it comes to connecting them to power. Despite all of the confusing terms and configurations, installing and wiring a backplane into a system is easier than you think. Our series on backplane terminology starts below.

"The ancient Romans had a tradition: whenever one of their engineers constructed an arch, as the capstone was hoisted into place, the engineer assumed accountability for his work in the most profound way possible: he stood under the arch."

What is a Power Bug?
A power bug (also called a tap) is a popular terminal used to connect power to a backplane. A bug mounts to the rear side of the backplane to fasten a supply voltage ring terminal. Typically, there are one or more power bugs for each voltage (+12V, -12V, 3.3V, and 5V) and ground. There will be more on this topic in the next issue.
