When disconnecting the IP cable to a 911 which act as a RSPD the RPUs goes offline, when connecting it again the RPUs stay offline.
Environment
Vista 5.1.6
Xenta 911 as RSPD, PLB and RPU 6751
Cause
The PLB object in the Vista database have somehow become corrupt.
Resolution
When creating new PLB objects and move the RPUs to that new object it works like it should.
