The multimode ST A/B switch latching card allows for the switching between two fiber connections, if power is lost the connection will stay in its current 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.
