Pick a card, any card. A/B Switch Cards are available for RS-232, video, fiber optic, and CAT5e/CAT6 connections. The card featured here is the DB25/RS-232. 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 and 75-ohm video 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. 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. Each chassis also has a keyed switch so you can enable/disable manual switching from the front-panel toggle switches. Ordering Instructions: First, order the chassis... Pro Switching System, 2U, 18-Card (SM260A) Next order at least one power supply Power Supply Cards: Redundant Power Supply Cards (NOTE: cards requires two chassis slots.): 100 - 240-VAC Input (SM261A-VAC) -48-VDC Input (SM261A-VDC) Or order: AC External Adapter Card (SM261A-CARD) ( NOTE: card requires one chassis slot.)
