Our Symmetra 20K shows a few messages in the event log like this :

Its happened before and I dismissed it as a fluke since it cleared 20 seconds later.
Since it now happened again does anyone know if were in trouble ?
Try to upgrade your network management card firmware.
link to apc site and choose your network management card model and download the firmware.
If it is intermittent it could be something simple like a fan fault. If you contact phone support we will be able to pull some more diagnostic info and see exactly what the problem is.
We saw the same thing with our Symmetra 20K.
We pulled out the faulty module and pulled an extra from our inactive Symmetra 20k and seated it.
The strange thing is when we did that Power Module 1 came back online as well as the power module (# 2) we replaced with the spare.
As of now we have all 3 power modules showing as installed and online.
