The Software Reset 2 jumper (S2), 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 holding the Software Reset 2 jumper (S2) 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".
To use it, simply shorten it with a screwdriver, and power up the device, until RouterOS loads.
JP5 DIS POE Jumper
This jumper will disable the 802.11af compatible smart PoE, and also lower the undervoltage protection
threshold to approx 10V, allowing to use this device with passive PoE in 24V Solar power installations.
