pins
There are several conditions needing a restart of the PBX. In
this case there are two ways of restarting the system:
•
Switch off the power supply either by disconnecting
from mains (unplug, switch off the supply lines) or
switch off the exchange using the switch at the bottom
of the cabinet.
•
Make a short between the two pins
(A32 and C32) on the connector at the front of the
CPU-D. Be careful when shorting these two pins by
using a plug with a wired connection or a jumper.
