4. Installing SFP devices
WARNING
Optical SFPs use an invisible laser to generate a fiber-optic signal. Always keep the port covered if a cable is
not installed. Do not look into the open port if a cable is not installed.
WARNING
If the surrounding air operating temperature of the PNC001 is greater than 40  C, SFP devices could have
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.
5. Configuring the PNC001 and its I/O Devices on a PROFINET network
PME is the primary tool used to configure an RX3i PROFINET network. In addition, certain parameters can be
set from a computer through the PNC001's Command Line Interface. For details on system planning and
configuration, refer to PACSystems RX3i PROFINET I/O Controller Manual, GFK-2571, Chapter 3.
CAUTION
Whenever an RX3i PNC001 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 PNC001 is plugged back into a powered backplane, the PNC001 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, superseding parameters previously stored in non-volatile memory.
