Motorola MVME2400 Series Installation And User Manual page 17

The MVME2400x interfaces to the VMEbus via the P1 and P2 connectors,
which use the new 5-row 160-pin connectors as specified in the proposed
VME64 Extension Standard. It also draws +5V, +12V, and -12V power
from the VMEbus backplane through these two connectors. The +3.3V and
2.5V power, used for the PCI bridge chip and possibly for the PMC
mezzanine, is derived onboard from the +5V power.
Support for two IEEE P1386.1 PCI mezzanine cards is provided via eight
64-pin SMT connectors. Front panel openings are provided on the board
for the two PMC slots.
In addition, there are 64 pins of I/O from PMC slot 1 and 46 pins of I/O
from PMC slot 2 that are routed to P2. The two PMC slots may contain two
single-wide PMCs or one double-wide PMC. There are also two RJ45
connectors on the front panel: one for the Ethernet 10BaseT/100BaseTX
interface, and one for the async serial debug port. The front panel also
includes reset and abort switches and status LEDs.
PMCspan Expansion Mezzanine
An optional PCI expansion mezzanine module or PMC carrier board,
PMCspan, provides the capability of adding two additional PMCs. Two
PMCspans can be stacked on an MVME2400x, providing four additional
PMC slots, for a total of six slots including the two onboard the
MVME2400x. The following table lists the PMCspan models that are
available for use with the MVME2400x.
