Product Features

  • Use with the Pro Switching System, 2U (SM260A).
  • Occupies one slot.
  • Many types of switch cards are available. See Ordering instructions (below).


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 Video F-Connector, Non-Latching. 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.
