3. Remove the filler panel from the VMEbus chassis card slot where

you are going to install the MVME5100. If you have installed one

or more PMCspan PCI expansion modules onto your MVME5100,

you will need to remove filler panels from one additional card slot

for each PMCspan, above the card slot for the MVME5100.

– If you intend to use the MVME5100 as system controller, it must

occupy the left-most 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 MVME5100 as system controller,

it can occupy any unused card slot.

4. Slide the MVME5100 (and PMCspans if used) into the selected

card slot(s). Verify that the module or module(s) seated properly in

the P1 and P2 connectors on the chassis backplane. Do not damage

or bend connector pins.

5. Secure the MVME5100 (and PMCspans if used) in the chassis with

the screws in the top and bottom of its front panel and verify proper

contact with the transverse mounting rails to minimize RF

emissions.

Note Some VME backplanes (such as those used in Motorola Modular

Chassis systems) have an auto-jumpering feature for automatic

propagation of the IACK and BG signals. The step immediately

below 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

slots occupied by the MVME5100 and any PMCspan modules.

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 MVME5100.

Note In normal operation, the host CPU controls MVME5100

operation via the VMEbus Universe registers.
