I have 4 ESR36 Racks with CEM+ Modules running software version 3.1.2.9.0.38
I have a number of ER15 modules
Some are older eg P/N 7070A2105 S/N245292
Some are newer eg P/N 7070A3305. S/N 318184
All of the relay modules work in rack 1, 3 and 4
However only the newer modules work in rack 2
I'm at a loss as to why this is
I have spoken to a few folks at etc nobody seems to be able to solve this
All racks installed at the same time (2011 I believe)
All racks are on the same group and same network
Can anyone help with this?
Thanks
Phil
