Understanding the
Installing the Cards in the DXP
1. Loosen the retaining hardware and remove the front panel from the DXP main cabinet.
2 . Turn off the AC power switch, and disconnect the AC power cord from the AC outlet. Disconnect the cable of the
optional battery back-up from the main cabinet power supply.
3 . Place a conductive mat in front of the cabinet area and ground the mat to a good earth ground (the third wire
ground of the AC power line is an acceptable grounding point). The grounded conductive mat will provide a safe
static electric discharge path.
4 . Install the static discharge wrist strap (supplied with the main cabinet) on your bare wrist; adjust it for a snug fit.
Be sure that the strap is touching bare skin and is not isolated by clothing. Connect the wrist strap cord between
the wrist strap and an AC or earth ground.
NOTE: With the common equipment in the installed position, the ground

appropriate grounding point since it should have a heavy ground wire connected between it and a good earth
ground.
Locate the
circuit board, loosen the retaining screws, remove it from the DXP main cabinet, place it
in a static protection bag, and transport it to the static-safe work area.
At the static-safe work area, with your wrist strap in place, remove the DXCPU-68K circuit board, the new
DXRAM-EXPC. expansion memory card and the new DXPSW-DLRC software memory card from their static
protection bags.
Refer to illustration and remove the currently installed memory cards from the
board.
Orient the
board and the new memory cards as shown in the illustration, and attach them with the
supplied hardware. (The screws and standoffs between the cards are essential to ensure proper grounding.)
Place the old memory cards in static protection bags and save them for later return for credit. Place the
DXCPU-68K board and newly installed memory cards into a static protection bag and transport back to the DXP
main cabinet.
10. With your wrist strap properly grounded, remove the
circuit board from the static protection bag.
Orient it with the top and bottom guides in the main cabinet board cage, and press it in firmly until the board edge
connector properly mates with the backplane connector.
When pressing the DXCPU-68K board into place, press it only at the extractor lever locations.
If
pressure at other locations, you may damage the board assembly.
11. Make a final inspection to ensure that the
circuit board is in the correct slot, oriented correctly and
mated properly; then install and tighten the supplied screws to secure it to the board cage.
