A method and apparatus of using DICE-T personality cards to adapt the incoming voltages supplied by the GVA and provide the ability to turn any voltage to any card on or off depending upon operating mode in a radio system is disclosed. The ability to control voltages individually also allows the control of the power-up sequencing of any card. The DICE-T personality cards use voltages from GVA to generate the additional voltages required by the Core Engines and VHF Module. All of the voltages are connected to hot-swap controllers which provide switching of the power to each destination. These hot-swap controllers also provide monitoring of voltage and shut-down if over-current conditions occur. The two DICE-T personality cards each have a Complex Programmable Logic Device (CPLD) controls the hot-swap controller for each voltage. The CPLD also controls the sequencing of the individual voltages applied to each module.
