CAUTION:
Do not touch the HDR3 header on the processor board; the header is
exposed when the feature module is not installed in the processor. If the
HDR3 header is removed, system programming may be deleted and will
have to be restored.
On the exposed portion of the processor board, find the header
marked HDR4 ; it is in the upper-left area.
A shunt is attached to one of the pins on the HDR4 header.
Remove the shunt from the single header pin; then reinsert it so
that it covers both pins on the header.
