Installation Considerations
PMC/SBC (761/IPMC) Mode Selection
There are five headers associated with the selection of the PMC or SBC mode: J4, J6 J10, J17
and J20. Three of these headers are responsible for secondary Ethernet I/O (J4, J10 and J17)
to either the front panel (PMC mode), or to the P2 connector via J4 (SBC mode). The other two
headers (J6 and J20) ensure proper routing of +/- 12V signal routing. The MVME5100 is set at
the factory for front panel I/O: PMC mode (see Table 1-1). The SBC mode should only be
selected when using one of the IPMC-7xx modules in conjunction with the corresponding
MVME7xx transition module.
The MVME5100 draws power from the VMEbus backplane connectors P1 and P2. Connector
P2 is also used for the upper 16 bits of data in 32-bit transfers, and for the upper 8 address lines
in extended addressing mode. The MVME5100 will not function properly without its main board
connected to VMEbus backplane connectors P1 and P2.
Whether the MVME5100 operates as a VMEbus master or as a VMEbus slave, it is configured
for 32 bits of address and 32 bits of data (A32/D32). However, it handles A16 or A24 devices in
the appropriate address ranges. D8 and/or D16 devices in the system must be handled by the
processor software.
If the MVME5100 tries to access off-board resources in a nonexistent location and if the system
does not have a global bus time-out, the MVME5100 waits indefinately for the VMEbus cycle to
complete. This will cause the system to lock up. There is only one situation in which the system
might lack this global bus time-out; that is when the MVME5100 is not the system controller and
there is no global bus time-out elsewhere in the system.
Note
Software can also disable the bus timer by setting the appropriate bits in the Universe
II VMEbus interface.
