text: <s>[INST] Unable to get Ethernet Comms working on Dual Port Ethernet Module - PowerFlex 525 Summary: Dual Port Ethernet Communications Setup ProblemsWe have a problem communicating to our PowerFlex 525 drives using the dual port ethernet interface from the stratix switch. Communication is OK if we use the embedded ethernet port. However, when we connect to the dual port interface we cannot ping the drive. Any thoughts? [/INST] https://literature.rockwellautomation.com/idc/groups/literature/documents/um/520com-um003_-en-e.pdf That's the user manual for the dual port Ethernet manual. Did you install it correctly? Did you install the interface connector that connects the card to the drive? It's easy to forget this part; it does not look important. How did you configure the ethernet address of the dual part card? Did you plug your Ethernet cable(s) into the dual port card (not the embedded port)? Sorry, these sound like stupid questions, but I've encountered an instance where each question was someone's solution. What do the card's LED status indicators show? \\n </s>
