Mounting

This device is designed for use indoors by placing it on a flat surface or mounting it on the wall, mounting points are shown in the picture below, and screws are not included in the package. Screws with size 4×25 mm fit nicely, depending on your wall structure you can use dowels 6×30 mm and 6 mm drill bit if needed.

Powering

The device accepts power from the power jack or from the first Ethernet port (Passive PoE):

Direct input power jack (5.5mm outside and 2mm inside, female, pin positive) accepts 8-30 V ⎓DC.
The first Ethernet port accepts passive Power over Ethernet 8-30 V ⎓DC. 12 V or more is recommended to compensate for the loss in cables.

The power consumption of this device under maximum load with attachments is 10 W. Without attachments 5 W.

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:
https://mt.lv/help. In case an IP connection is not available, the Winbox tool (https://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 Internet port by default).
For recovery purposes, it is possible to boot the device from the network, see a section Reset button.
Extension Slots and Ports
The device has five individual Ethernet ports, supporting automatic cross/straight cable correction (Auto MDI/X), so you can use either straight or cross-over cables for connecting to other network devices.

MicroSD card slot.
USB type-A slot.

Buttons and jumpers

Reset button

The RouterBOOT reset button has the following functions. Press the button and apply the power, then:

Release the button when the green LED starts flashing, to reset the RouterOS configuration to defaults.
Release the button when the LED turns solid green to clear all configurations and bridge all interfaces.
Release the button after LED is no longer lit (~20 seconds) to cause a device to look for Netinstall servers (required for reinstalling RouterOS over the network).

Regardless of the above option used, the system will load the backup RouterBOOT loader if the button is pressed before power is applied to the device. Useful for RouterBOOT debugging and recovery.
