Note that JA1 and JB1 are located on the personality module (in the top of
the box when it is standing vertically). JB1, on the front of the module, is
visible. JA1 is on the left side of the personality module as you face the front
of the BA356, and is hidden from the normal view.

To determine if a jumper module or terminator module is installed in a
BA356, remove the devices from slots 1 and 6 and note the following pin
locations (see Figure 9–8):

The identification pin on a jumper module aligns with the top hole in
the backplane.

The identification pin on a terminator module aligns with the bottom
hole in the backplane.
