When I run test port 5 of the ports fail and 3 pass. Can anyone help me with this problem.
Hello,
Make sure to disconnect all serial cables/devices from all 8 of your Edgeports serial ports before running the digital loopback test. Close and re-open the Edgeport Configuration Utility too, after disconnecting all of those cables/devices, before running the digital loopback test.
Does this help?
