Caution
Avoid touching areas of integrated circuitry; static discharge can damage
these circuits.
4. Slide the MVME240x (and PMCspans if used) into the selected
card slot(s). Be sure the module or modules is/are seated properly in
the P1 and P2 connectors on the backplane. Do not damage or bend
connector pins.
5. Secure the MVME240x (and PMCspans if used) in the chassis with
the screws provided, making good contact with the transverse
mounting rails to minimize RF emissions.
Note Some VME backplanes (for example, those used in Motorola
“Modular Chassis” systems) have an auto-jumpering feature for
automatic propagation of the IACK and BG signals. Step 6 does
not apply to such backplane designs.
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 MVME240x.
7. If you intend to use PPCBug interactively, connect the terminal that
is to be used as the PPCBug system console to the
DEBUG port on
the front panel of the MVME240x.
In normal operation the host CPU controls MVME240x operation
via the VMEbus Universe registers.
8. Replace the chassis or system cover(s), cable peripherals to the
panel connectors as appropriate, reconnect the system to the AC or
DC power source, and turn the equipment power on.
9. The MVME240x’s green
CPU LED indicates activity as a set of
confidence tests is run, and the debugger prompt
PPC1-Bug>
appears.
