2.9 REDUNDANT IPDP SERIAL LINK
The IPDirector communicates with the XT2+ server via one serial link. If that link
fails, the XT2+ server can no longer be controlled by any IPDirector.
From Multicam version 10.01, a failover mechanism has been put into place. This
mechanism will switch the IPDirector link from one port of an XT2+ server to
another port on another XT2+ server.
To ensure the failover, the backup links between IPDirector workstations and the
XT2+ servers need to be physically cabled to a second RS422 port, as shown on
the following schema:
The serial link redundancy will ensure that there is no single point of failure in the
setup. However, you need to put into place a thoroughly thought through IPDP
configuration for the SynchroDB to continue working correctly. This can be
achieved, for example, by defining an IPDirector workstation in Network mode.
