compensate for the loss in cables.

Booting process
RouterOS includes many configuration options in addition to what is described in this document. We suggest
starting here to get yourself accustomed to the possibilities: http://mt.lv/help. n case P connection is not available,
the Winbox tool (http://mt.lv/winbox) can be used to connect to the MAC address of the device from the LAN side
(all access is blocked from the nternet port by default).
For recovery purposes, it is possible to boot the device from the network, see a section Reset button .

The RouterBOOT reset button has the following functions. Press the button and apply the power, then:
•Release the button when a green LED starts flashing, to reset RouterOS configuration to defaults.
