MikroTik RouterBOARD 1100 - Software Reset; Software Reset Functionality

10
The Software Reset 2 button (TP12) reset hole, which resets both boot loader settings and RouterOS setting by
default, can be disabled in this menu (it will still reset the boot loader settings).
Software Reset
It is possible to reset all software configuration by using the Software Reset 2 button hole (C229, see
schematic) during the power-up. No confirmation or passwords will be asked, so use with caution. This feature
can be disabled in the “system routerboard settings” menu by switching the “enable-jumper-reset”
parameter to “no”. Simply use a metal object to short circuit the metallic reset hole (TP12) while booting.
