Each site must have a PZ-(X)IPLA/IPLB daughter board and a PZ-ME50-US Memory Expansion
Daughter Board installed on its CD-CP00-US blade. The CD-CP00-US blade at each Remote Site must
have the same data as the Main Site CD-CP00-US blade. The Main Site automatically uploads the
system data to the Remote Sites anytime it changes.
The Main Site requires a proper LK-SYS-NETLINKX-LIC license for each Remote Site.
When a communication failure occurs between the Main Site and any Remote Site, the Main Site
CD-CP00-US blade automatically changes to survival mode and operates as a stand-alone system. If
multiple Remote Sites are installed, a Remote Site can be assigned as a temporary Main Site to control
remaining connected sites.
