the top cover. Do not remove the power unit safety
cover.
Step 3
Remove the rear panel SysNet option slot blanking
plate by unscrewing the two fixing screws.
Locate and carefully unplug the 26way harness that
connects between the CPU and Connector circuits.
Step 4
Fit the snap-in mounting pillars to the track side of the
SysNet card and mount the assembly into the DR66
rear panel using the two fixings attached to the D-type
connector.
Fold and position the new 26way harness as shown
plugging it into the CPU, Connector and SysNet cards.
Note the position of the pin 1 red stripe.
Make sure the harness pins are correctly aligned with
the mating connector pins. Push the plugs fully home.
