If the stake pins are on the rear of the backplane, the most common location is in the
middle of the J1 connector as shown in Figure 2-5 below. This can be just these pins
extended or all pins extended for wirewrapping.
The stake pins (front or rear) can also be located adjacent to the slot being jumpered
as shown in Figure 2-6 above. Typically, the stake pins are located between the slot
being jumpered and the next lower-numbered slot (e.g. jumpers for Slot 6 would be
located adjacent to Slot 6 between Slots 5 and 6).
Consult your VME chassis reference manual or contact the chassis manufacturer if
you are unsure where to jumper your particular system.
