3.1 General Information
There are two kinds of backplanes for MIC-3042 series. MIC-3042A and MIC-3042B
are with H.110 CT bus backplane. Both backplanes provide eight CompactPCI™ slots
with one slot dedicated to the CPU board. The MIC-3042 supports front I/O wiring,
providing simplified system cabling. The backplane also provides several 3-pin
connectors to connect hot-swappable cooling fan module. In order to provide users
with a flexible system configuration, the MIC-3042 includes one standard ATX power
connector to accept one ATX power supply. The MIC-3042 complies with PICMG 2.1
Hot-Swap Specification, providing full hot-swapping capability. Users can build a
hot-swap system using hot-swap plug-in boards and software.

3.4 Slot Assignments
The CompactPCI™ specification defines slot numbering separation for physical and
logical slots. Each slot has a physical number and a logical number (refer to the
CompactPCI™ specification version 2.0 R3.0 for further information on slot
assignments). The physical numbers are printed on the backplane, enclosed in
circles or triangles. Slot1 of MIB-3042A and slot2 of MIC-3042B, marked by a
triangle, is the system slot and can only be used by a CPU board. The other slots are
