OPERATION CHECK OF STANDING BOARDS ON THE MOTHER BOARD
The standing boards connected to the MOTHER board via the connectors can be operated using the jig with the standing boards discon-
nected from the MOTHER board.
In such a case, for the board with the bracket (back panel), remove the board together with the bracket from the MOTHER board, and
connect the bracket to the chassis using a cable attached with alligator clips for GND connection.
