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. 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 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, and Groove will start to look for Netinstall servers.
In case IP connection is not available, the Winbox utility can also be used to connect to the MAC address of the
device. More information in the documentation.
