5. Attach the four standoffs to the VME processor module. For each

standoff:

– Insert the threaded end into the standoff hole at each corner of

the VME processor module.

– Thread the locking nuts onto the standoff tips.

– Tighten the nuts with a box-end wrench or a pair of needle nose

pliers.

Note On the MVME2600, use the short standoff in corner with the

LED mezzanine module.

Caution

Do not remove an MVME3600 or MVME4600 processor

board from the base board. Use a small box-end wrench or

needle nose pliers to hold the nut in place.

6. Place the PMCspan on top of the VME processor module. Align the

mounting holes in each corner to the standoffs, and align PMCspan

connector (P4 or P5) with VME processor module connector (J4 or

J5).

7. Gently press the PMCspan and VME processor module together,

making sure that P4/P5 is fully seated into J4/J5.

8. Insert the four short Phillips screws through the holes at the corners

of the PMCspan and into the standoffs on the VME processor

module. Tighten the screws.

Note The screws have two different head diameters. Use the

screws with the smaller heads on the standoffs next to

VMEbus connectors P1 and P2.
