Booting process

The device is preinstalled with MikroTik RouterOS software. It can be configured in several ways.

This device doesn't come fitted with a Serial Port connector, so initial connection has to be done via the Ethernet cable, using the MikroTik

Winbox utility (available on www.mikrotik.com). Winbox should be used to connect to the default IP address of 192.168.88.1 with the

username admin and no password.

In case IP connection is not available, Winbox can also be used to connect to the MAC address of the device. More information about

configuring the device: http://wiki.mikrotik.com/wiki/First_time_startup

In case you wish to boot the device from network, for example to use MikroTik Netinstall, hold the RESET button of the device when

starting it until the LED light turns off, then release the button and the device will start looking for Netinstall servers.

By default, the device is preconfigured with a simple firewall on the WAN port, this configuration can be viewed when first connecting to

the Router via Winbox. It will ask whether to keep this configuration or clean it to use your own. LAN/WLAN ports have DHCP server

enabled.
