ZT 5550 Performance Technologies Pentium III cPCI Single Board Computer

The Ribbon / Performance Technologies / Ziatech ZT 5550 is an Intel Pentium III processor-based single board CompactPCI computer. Two ZT 5550 CPUs can be used on the same backplane, as an Active/Standby System Master pair, or as a Split Mode (Revision D and later boards) Standby System Master pair, to provide redundancy for the ZT 5083 and ZT 5084 High Availability (HA) Systems designed for mission-critical telecommunication and industrial control applications requiring 99.999% availability. The ZT 5083 and ZT 5084 systems incorporate redundant ZT 5550s, power supplies, and cooling fans in a single enclosure. Each ZT 5550 can be an Active, Standby, or Split Mode (Revision D and later boards) Host CPU. Resource management and database information is synchronized between the Active, Standby, and Split Mode (Revision D and later boards) Hosts via a bi-directional serial channel and an Ethernet* channel.

The ZT 5550 utilizes the Intel Pentium III Processor Mobile Module: Embedded Module Connector 2 (EMC-2) to provide extremely high PCI performance and the latest in memory and I/O technology. An active ZT 5550 is designed to function in the System Slot controlling the CompactPCI backplane.

Each ZT 5550 supports attachment of an optional 6U I/O Expansion Board (such as the ZT 96072 or ZT 96073). I/O Expansion boards (IOX) are designed to greatly expand the I/O capability of the ZT 5550. Rear-panel access to the CPU/IOX combination can be provided by rear-panel I/O (RPIO) transition boards (such as the ZT 4804 and ZT 4802).
