Does the NTP need to be configured on all NMCs for all parallel Galaxy VS?

Published date: 09 March 2020

Issue:
Does the NTP need to be configured on all NMCs for all parallel Galaxy VS.  These includes Internal NCM and optional AP9644 NMC.


Product line:
Galaxy VS


Environment:
Galaxy VS


Cause:
Configuring NTP on multiple NMCs for parallel UPSs can cause issues like excessive time stamp events in the log files.  Parallel Galaxy VSs communicate between each other and they will try sync the date and time which can cause a loop of trying to set the date and time.  The above communication is also true for the internal NMC and the optional AP9644 NMC.  They communicate to each and the same logging issue can occur.


Resolution:
Ensure that only one network management interface in the entire UPS system (single or parallel) is set to synchronize time.
