Plant lost power Saturday night, came in for nights and the case packer remote rack is down. Main rack is a 1756 L83E with a 1756 EN2T in slot 2, remote rack is a 1734 AENTR.
The EN2T itself looks fine in the tree and everything under it has the yellow triangle. Connection tab on the AENTR says (16#0204) Connection Request Error: connection timed out. EN2T has OK solid green, and the little display on the front just scrolls BOOTP over and over. We power cycled the main rack twice and reseated the EN2T, same thing.
There's a spare EN2T on the shelf. Is it just dead? Asking first, because last time somebody swapped one it took half a day to get talking again. Any thoughts before I pull the trigger on a swap?
Don't swap it. Display scrolling BOOTP is the whole story, the module has no address. What are the three rotary switches on the front set to? Photo, they're small. And is anything on that network acting as a BOOTP server, or was there ever one?
New here and I've got the same EN2T on our line. Not sure what BOOTP on the display actually means, is it waiting for something?
