text: <s>[INST] PowerFlex 70. Migrating from 20-COMM-D to 20-COMM-E. Retaining original VFD's. I have an MCC full of PowerFlex 70s that I need to cut over to Ethernet. I need to retain the existing drives. Does anybody have any experience, how-to's, or input as how to proceed. Stratix 5700's in place, cables pulled. Just need to swap the comms modules and make them work. [/INST] What controller are you using? I would suggest making sure the ethernet switch is configured prior to attempting the switchover. I feel like I fight them (Stratix5700) a lot during initial commissioning. Regards, RM \\n </s>
