Black Box Pro Switching System Plus A/B Switch Product Details

For fail-safe operation, the cards use proprietary latching or micro-mirror relay switching technology - which means data can continue to pass through even if the power has been cut off. Because the cards perform Layer 1 switching, the system operates independently of data rates, protocols, formats, or signal levels.

The non-latching fiber cards fall back to a Port C (chassis) to Port A connection when the power fails. When power is restored, the non-latching switch card reconnects Port C to the originally selected port (A or B). These types of cards are typical when you want a fallback or failover connection during power outages.

The chassis also has a keyed switch so you can enable/disable manual switching from the front-panel toggle switches.
