A passive backplane is a computer board used in rackmount chassis that allows the user access to peripheral cards such as Dialogic, LAN, or USB cards. A passive backplane needs an SBC (Single Board Computer) to function.
Passive backplanes are the perfect choice for industrial computing solutions as they allow you a large amount of expansion without having to add computers. Most motherboards only provide 5-7 slots while a typical 20 Slot passive backplane can hold up to 15 additional PCI cards with the SBC installed.
