Preparing and Installing the MVME2400-Series Module

–If you intend to use the MVME240 x as system controller, it must occupy the leftmost card slot (slot 1). The system controller must be in slot 1 to correctly initiate the bus-grant daisy-chain and to ensure proper operation of the IACK daisy-chain driver.

–If you do not intend to use the MVME240 x as system controller, it can occupy any unused card slot.

Avoid touching areas of integrated circuitry; static discharge

! can damage these circuits.

Caution

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 (e.g., 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.
