Building my lab, strange problem with one of the routers.
Im putting together my CCNP lab, I picked up 4 1721s and a 1760. For Wics i have 6 of the 1DSU-T1 and 1 1DSU-T1-V2. They all are running the same version of 12.4 and have 32mb flash and 64 mb ram. One of the 1721s crashes on boot when any of the 1DSU-T1 Wics are installed in either slot, says %Software-Forced reload. The other 3 come up fine with any of the wics. I was able to get the problem router to boot with the V2 card in it though. I did a brief google search and found the results less than helpful. Anyone have any ideas? Only thing i can think of trying is reloading the IOS from backup and im not too confident in that helping.
