17 Reposition the EMI shield (it looks like a brass grill) in the base of the
module. Tape over the front mounting tabs to hold the shield in position.
You will remove the tape later.
18 Slide the new card cage about halfway into the module. Hold the card
cage firmly while attaching the power system connectors to the rear of
the module (see Figure 8-24):
• Attach the new frame ground (green) wire to the frame ground post
in each module. (A 5/16" socket wrench is needed for this
operation.) Remove the nut and the lock washer at the top of the
post. Put the frame ground connector over the post. Reinstall the top
lock washer and the nut, then tighten the nut.
Note: For all of the terminal lugs to fit on the post, you must remove one
of the lock washers. Leave a lock washer at the bottom of the post and at
the top of the post. Leave a third lock washer between the second and
third, or the third and fourth terminal lugs.
