I have a 1756-ENBT Card in a 7 slot rack. Tried swapping it to a 1756-EN2T configured identically for ip/subnet/gateway and could not ping it from the very same programming terminal that had beena ble to ping the ENBT. Tried a direct connect cable and could ping it.
Suspected something in the switch, but IT say not.
Today tried 1756-EN2T in an open slot with another IP address and it pings.
This leaves Cable, Switch Port or IP Address as potential issues.
Any thoughts?
