14) Place the nuts, washers and AccuVote-OS buttons in a secure location. Ensure that the six
nylon washers underneath the CPU board on the standoffs are all present and not stuck to the
underside of the CPU board.
4.2.6. Installing the CPU board
Ensure that all external cables are disconnected from the unit and the unit is powered off before
installing the CPU board. No memory card should be loaded into the AccuVote-OS before
installing the CPU board.
1) Ensure that six nylon washers are in place on the standoffs before installing the CPU board.
Ensure that the standoffs are tight on the chassis. Tighten any loose standoff by using a ¼” nut
driver on the standoff and a Philips (+) screwdriver on the screw head on the bottom of the
chassis.
2) With the front edge of the board angled downward, slide the board into place, making sure the
pushbutton posts are properly aligned with their holes in the chassis. Clear any of the wires
blocking the installation of the CPU board assembly.
3) Lower the CPU board onto the standoffs and secure in place, in the following order:
•
the nylon washers
•
the lock washers
•
the nuts
Push the washers down over the threads or rotate the washers clockwise as you install them.
Using a ¼” nut driver, tighten each of the six nuts in order to connect the CPU board to the
chassis.
4) Replace the AccuVote-OS and button pads on the pushbutton posts, ensuring that the pads
have freedom of movement in the chassis holes, and that they do not stick. Push these in from
the chassis exterior.
If the pushbutton pads do not have freedom of movement, remove the pads and gently align the
pushbutton posts towards the center of the chassis holes.
The pushbutton posts should be
aligned with care as their connection to the CPU board may become damaged if excessive force
is applied
.
5) The following cables must be reconnected to the CPU board:
•
static discharge strap
•
four-wire power supply cable
•
three-wire deflector connector cable
•
main serial port cable
•
modem serial port cable
•
two-wire modem power cable
•
ballot reader serial cable
•
static discharge straps
Before reconnecting the ribbon cables ensure that all locking eject levers are splayed outwards.
6) Plug the four-wire power supply connector into the male connector next to the printer assembly
on the CPU board.
7) Plug the three-wire deflector connector cable connector into the male connector on the right
hand side of the four-wire power supply cable.
