Pro Switching System, 2U, A/B Switch Cards

Pick a card, any card.
A/B Switch Cards are available for RS-232, RS-530 and CAT6 connections. Use the system for both new and legacy applications. You can add cards for fast CAT6 10-GbE networking while keeping connections for older RS-232 connections.

Secure and fallback switching.
For fail-safe operation, all the cards (except those noted) 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.

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