Circuit card grid
Some circuit cards contain option switches or jumpers, or both, that define
specific functions. A switch or jumper can be identified by an alphanumeric
coordinate (such as D29) that indicates a location on the card, or by a
switch number (such as SW2) printed on the circuit board (see
). Positions on a switch (for example, positions
1, 2, 3, and 4 on SW2) are labeled on the switch block.
On a circuit card:
•
ON may be indicated by the word "on," the word "up," the word
"closed," the number "1," an arrow pointing up, or a solid dot (•).
•
OFF may be indicated by the word "down," the word "open," the
number "0," or an arrow pointing down.
Throughout this document, if neither ON nor OFF is given (there is a blank
space) for a position on a switch, that position may be set to either ON or
OFF because it has no function for the option described.
