Removing the Backplane Knockout

The IC695PNC001 must be installed in the main (CPU) rack of the RX3i system, using a
Universal Backplane such as IC695CHS007, CHS012 or CHS016. For details, refer to the
PACSystems RX3i System Manual, GFK 2314.
The rear of the PNC001-Ax module has an exposed heat sink and backplane connector.
Before inserting the module into the backplane, remove the plastic knockout in the slot into
which the module will be placed. The installation slot must match the slot selected for the
module in the PAC Machine Edition hardware configuration. This action is not required for
PNC001-Bxxx. However, if the knockout has been previously removed, the PNC001-Bxxx
can still be inserted into that slot location.
