Two probabilistic models of a duplicated standby system subjected to random shocks during the repair are discussed. Each unit consists of mixture between hardware and software components that work together and fail independently. The first model contains regular repairman. During the repair of hardware components the regular repairman can cause a shock and damage the unit. In the second model there is an expert repairman to avoid the occurrence of shocks and to study the effect of experience level on the system. Several reliability measures for the proposed system are obtained. Finally numerical study is done to clarify the results
