Recently we got a WIC-1DSU-T1-V2. The current configuration is WIC-1DSU-T1-V1 in slot 0, nothing in slot 1, nothing in slot 2 and slot 3 (Voice slots). I added the new WIC-1DSU-T1-V2 in slot 1 and realized that the current IOS on the router(12.2.11.T3) does not support the new WIC. I downloaded and put a newer version of the IOS (12.3.15a) on the router. On the flash, in position 1 there is the old IOS (12.2.11.T3) and in position 2 there is the new IOS (12.3.15a). Set the no system boot, and system boot flash 12.3.15a. write startup-config, then reloaded. Now when the router boots up (with the old WIC in slot 0 and new WIC in slot 1) it decompresses the old image (12.2.11.T3) and loads it. Then it tries to load up 12.3.15a, hangs up for a bit, then it boots up the old IOS (12.2.11.T3). Grr.. Any one have this same problem? I've tried 2 other IOS's thinking maybe it's a version conflict and i've had the same problem. I can't think of anything else to do so any suggestions will be greatly appreciated. ADVthanksANCE!
