General Information

The RJ45 CAT5e A/B switch latching card allows for the switching between two Ethernet connections with speeds up to 1 GbE, if power is lost the connection will default to the A location.

Controller Cards take up only one slot, and external power connects to the controller card, One slot is reserved for future use, leaving you with 16 slots for A/B Switch Cards. All switch cards take up one slot except for the power A/B cards which take up two slots. Manage access to networks, implement backup systems for network and computer connections, or share peripherals and other equipment.

Local features include LED status and manual switching. Remote control (dry contact closure, RS232, and Ethernet) provides unmatched management flexibility.

Gang Switch systems are used around the world to add secure access control and reliable backup for critical systems from space launch centers to stock exchange networks.
