I'm prepping for an upgrade and slowly upgrading the TN circuit pack firmware, where able. I have a few TN771DP's. I updated one with no problem, but the next one is not showing the new firmware. The steps to execute the firmware download all went fine and I did status the download, which lookeded to complete. When I do a list config the vintage has not changed. I tried a second time and caused a minor alarm, which cleared itself but same issue with no updated vintage.
