Hot Insertion and Removal

Modules in a Universal Backplane can be installed or removed while power is applied to the
system. This includes backplane power and field power supplied to the module. For a full
discussion of this topic, refer to the Hot Insertion and Removal section in the PACSystems
RX3i System Manual, GFK 2314.
The PNC001 module must be properly seated with the latch engaged (PNC001-Ax only) and
all pins connected within 2 seconds. For removal, the module must be completely
disengaged within 2 seconds. It is important that the module not remain partially inserted
during the insertion or removal process. There must be at a minimum of two seconds
between the removal and insertion of modules.
