4.1Preparing Your Work Area

Before starting the upgrade, make sure your work area has the proper anti-static
safeguards.
Place the new an old chassis side by side. Make sure the power switches are off, but
each unit should have its AC power cord unplugged. To transfer equipment from your
old chassis to the new chassis, you will need a #2 phillips-head screwdriver and 3/16"
hex-nut driver.

Paddle Cards
The first thing you want to do is remove all the terminal and other types of I/O cables
attached to the rear panel of your old computer. Next, remove the four screws that hold
the new computer's I/O rear panel in place. Then, transfer all the rear panel paddle
cards from your old chassis over to the new computer's I/O rear panel bracket. Each
paddle card is held in place with three screws. Once all the paddle cards are secured to
the new computer's I/O rear panel bracket, set the rear panel bracket and paddle card
assembly aside until later on in the procedure.

Remove the two screws that hold your CPU board in place in your old chassis and the
slide the CPU board out. Before removing the VME expansion boards, mark the order in
which they are installed in your old chassis. Remove all of your VME expansion boards.
