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.
Inserting or removing a module with power applied to the system may cause an
electrical arc. This can result in unexpected and potentially dangerous action by
field devices. Arcing is an explosion risk in hazardous locations. Be sure that the
area is non-hazardous or remove system power appropriately before removing
or inserting a module.
Warning
If the surrounding air operating temperature of the PNC001 module is greater
than 40°C (104°F), SFP devices could reach operating temperatures over 70°C
(158°F). Under these conditions, for your safety, do not use bare hands to
remove an SFP device from the SFP cage. Use protective gloves or a tool
(needle-nose pliers) to avoid handling the hot SFP device directly when
removing the SFP device.
Warning
If an RX3i PROFINET Controller is extracted from a powered RX3i backplane, it
loses power immediately, which may result in data loss. Do not remove or
insert the device while downloading hardware configuration to the system.
When the module is plugged back into a powered backplane, the PNC001
module restores data from the internal non-volatile memory. If, however, the
RX3i CPU has configuration data for the PROFINET Controller, it re-delivers the
data to the PNC001 module, superseding parameters previously stored in non-
Caution
volatile PNC001 memory.
2.6.1.1 Fault Notifications
Removing a PROFINET Controller causes a Loss of IOC fault in the RX3i CPU's I/O Fault Table and inserting a
PROFINET Controller causes an Addition of IOC fault in the I/O Fault Table.
