The PMCspan board provides VMEbus processor

modules with greater expansion capabilities

• Single-slot 6U VMEbus format

• PLX6150 PCI-to-PCI interface bridge

• Support for two single-wide or one double-wide PCI Mezzanine

• Card (PMC) per PMCspan

• Stacking capability

• Front-panel and/or P2 I/O

• Compliant with PCI local bus specification (revision 2.1)

• Injector/ejector handles per VME64 extensions

• Compatible with Emerson’s PowerPlus VME series

The Emerson Network Power PMCspan board allows users to customize their exact I/O

requirements with Emerson’s VME-based CPU modules designed around the PowerPlus architecture.

When a PMCspan board is coupled with an Emerson processor module, the system

provides up to six PCI Mezzanine Cards (PMCs), more expansion capability than any

other VME-bus processor module. Each PMCspan board supports either two single

wide or one double-wide PMC. By stacking PMCspan boards onto a processor module,

a total of four additional single-wide PMCs can be added to Emerson’s compute

engines – either today or as future application growth demands.

The PMCspan is a standard 6U single-slot VMEbus module that links to its host board

via a PCI expansion connector. It supports both front panel and P2 I/O access for customer supplied

PMCs.
