Hi there. I have an USR Total Control Chassis with a Hiper DSP Card (ver 2.1.9), Hiper ARC Card (5.0.9) and an NMC (6.0.9). The problem is that the Hiper ARC is unable to see the Hiper DSP Card (shows chassis slot is empty). I have tried different combinations of chassis slots with no good result. I have even tried to change the chassis with no positive results either. I was wondering if anyone has experienced this or has any suggestions on how to solve the problem. Interestingly enough, using TCM, I am able to recognize both the Hiper ARC card and the Hiper DSP. Cheers, Patrick Ndegwa, Technical Operations, UUNET Kenya Ltd.
