6. On the chassis backplane, remove the INTERRUPT ACKNOWLEDGE
(IACK) and
BUS GRANT (BG) jumpers from the header for the card
slot occupied by the MVME172LX.
7. Connect the appropriate cable(s) to the MVME172LX panel
connectors for the EIA-232-D serial ports, SCSI port, and LAN
Ethernet port.
– Note that some cables are not provided with the MVME172LX
and must be made or purchased by the user. (Motorola
recommends shielded cable for all peripheral connections to
minimize radiation.)
8. Connect the peripheral(s) to the cable(s).
9. Install any other required VMEmodules in the system.
10. Replace the chassis cover.
11. Connect the power cable to the AC power source and turn the
equipment power ON.
System Considerations
The MVME172LX draws power from both the P1 and the P2 connectors
on the VMEbus backplane. 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 MVME172LX may not operate properly without its main board
connected to VMEbus backplane connectors P1 and P2.
Whether the MVME172LX 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 address ranges indicated in
Chapter 3. D8 and/or D16 devices in the system must be handled by the
MC68060/MC68LC060 software. Refer to the memory maps in the
MVME172 VME Embedded Controller Programmer’s Reference Guide.
