4. Attach the four standoffs to the MVME240x 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.
5. Place the PMCspan on top of the MVME240x module. Align the
mounting holes in each corner to the standoffs, and align PMCspan
connector P4 with MVME240x connector J6.
6. Gently press the PMCspan and MVME240x together, making sure
that P4 is fully seated into J6.
7. Insert the four short Phillips screws through the holes at the corners
of the PMCspan and into the standoffs on the MVME240x 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.
Secondary PMCspan
The PMCspan-010 PCI expansion module mounts on top of a PMCspan-
002 PCI expansion module. To install a PMCspan-010 on your
MVME240x, refer to Figure 1-5 and perform the following steps. This
procedure assumes that you have read the user’s manual that was furnished
with the PMCspan, and that you have installed the selected PMCs on the
PMCspan according to the instructions given in the PMCspan and PMC
manuals.
1. Attach an ESD strap to your wrist. Attach the other end of the ESD
strap to the chassis as a ground. The ESD strap must be secured to
your wrist and to ground while you are performing the installation
procedure.
