PMCspan

A PMCspan front panel is pictured on the previous page. The front panel is the same for all PMCspan models.

There are two PMC slots, labeled PCI MEZZANINE CARD, which support either two single-wide PMCs or one double-wide PMC.

The PMCspan board has two sets of three 32-bit connectors for PMC interface to a secondary PCI bus and a user-specific I/O. It also has a P1 connector and a 5-row P2 connector for power and VMEbus I/O.

The PMCspan has two green LEDs on its front panel, one for each PMC slot, labeled PMC2 and PMC1. Both LEDs are illuminated during reset. An individual LED is illuminated whenever a PMC has been granted bus mastership of the secondary PCI bus.

The right-most (lower) opening labeled PCI MEZZANINE CARD on the front panel is Port 1.

The left-most (upper)opening labeled PCI MEZZANINE CARD on the front panel is Port 2.
