PCC 4 allows multiple DCE to be specified for failover purposes. Despite this, there can be cases where this does not behave as expected.
For example, if primary DCE is down, PCC goes offline most of the time instead of connecting to the secondary DCE and it is not recovered unless the primary DCE comes back online (PCC connects back to primary DCE) or the MFP is rebooted (PCC will connect to the next available DCE).
This issue might happen if using PCC version 4.2.3.0166 or older.
Install PCC version 4.2.3.0168 or newer.
