Supermicro C7Z270-CG-M Motherboard User’s Manual
2-8 Jumper Settings
Explanation of Jumpers
To modify the operation of the mother-
board, jumpers can be used to choose
between optional settings. Jumpers
create shorts between two pins to
change the function of the connector.
Pin 1 is identified with a square solder
pad on the printed circuit board.
Note:
On two pin jumpers, "Closed"
means the jumper is on, and "Open"
means the jumper is off the pins.
Manufacturing Mode (JPME2)
Close Pin 2 and Pin 3 of Jumper JPME2
to bypass SPI flash security and force
the system to operate in Manufactur-
ing Mode, allowing the user to flash the
system firmware from a host server for
system setting modifications. See the
table on the right for jumper settings.
