Jumpers - Supermicro SuperServer SYS-220TP-HTTR User Manual

4.4 Jumpers

Explanation of Jumpers
To modify the operation of the motherboard, jumpers are used to choose between optional
settings. Jumpers create shorts between two pins to change the function associated with it.
Pin 1 is identified with a square solder pad on the printed circuit board. See the motherboard
layout page for jumper locations.
Note: On a two-pin jumper, "Closed" means the jumper is on both pins and "Open" indicates
the jumper is either on only one pin or has been completely removed.

JPTG1 allows the user to enable or disable the onboard LAN ports. The default setting is

LAN ports when the system is in power off status. The default setting is to short pins 2-3 to
disable onboard LAN ports when the system is in power off status. Refer to the table below
