A plurality of PODs for a lower marine riser package (LMRP) is disclosed. At least a first subsea electronics module (SEM) and a second SEM are provided in a first POD of the plurality of PODs. At least a third SEM and a fourth SEM are provided in a second pod. The third SEM is redundant with the first SEM and the fourth SEM is redundant with the second SEM. At least one selector circuit is provided to transmit an SEM select signal that electrically activates or electrically deactivates the first SEM separately from the third SEM. As a result, each of the SEMs in the plurality of PODs may be separately activated or deactivated without a need to turn off fluid provided to hydraulic valves in the first and the second PODs that are controlled by corresponding SEMs.
