"The VM3200 can be equipped with dual power modules to ensure that the system is always working. The power modules are hot-pluggable and can be easily replaced without shutting down the system. The VM3200 has two power slots that can connect to two different power supplies. If the primary power fails, the secondary power supply will automatically take over.
