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.
