The slots are numbered from 0 to 7. The software does not depend on the board being installed in a particular
slot, but installing the first board in slot 0, the second in slot 1, and so on makes the installation of each succeeding
board easier. It is important that each board be handled as few times as possible.
Step Seven:
Confirm that the wrist-strap is grounded. Remove the modem board from its anti-static packaging, being careful
to not touch the components or metal parts of the board (see the figure).
