Troubleshooting Solid Red LED on 1734-AENT EtherNet/IP Adapter Module: Resolving Firmware Errors

Question:

We have encountered an issue with our POINT I/O EtherNet/IP Adapter Module, model 1734-AENT, Rockwell, series A revision 2. The Module Status LED is displaying a solid red light. What steps can we take to resolve this issue? The user manual identifies a potential cause. Would re-downloading the firmware help address the situation? The error message reads: "Firmware Fatal Error: An unrecoverable fault has occurred due to a self-test failure, which may be related to a checksum failure or RAM test failure upon power cycling."

It sounds like you're dealing with a pretty frustrating issue! Since the error message points to a firmware fatal error, re-downloading the firmware could definitely be a good step to try as it might help reset any corrupted data that caused the self-test failure. Before you do that, though, make sure to check the module's power supply and connections just to rule out any simple issues. If the firmware reinstall doesn’t work, you might need to consider contacting Rockwell support or looking into a replacement if it's still under warranty. Good luck!
