One FWSM failed - H/W fault. A new FWSM was used to replace failed module. Since then we cannot get redundancy to work.
Could it be that one FWSM is at version 2.3(3) and the other one is at 2.3(2). But customer said that this difference was there even before and they did not have any problem before the H/W fault.
