I have a TA 1500 SCU card and I get no login prompt. Has anyone had this problem? This has happened a few times and the only way I can get it back is to re-seat the card and it affects all the circuits.
You should be able to reseat the SCU card without affecting service in the shelf. If reseating SCU is causing circuits to drop you may want to swap it out with spare SCU if you have one.
