1 Precautions Before Setup & First Run
•If your network contains managed/smart switches such as (Cisco, Allied Telesis etc.)
•RSTP, STP (Spanning Tree Protocols) and related protocols must be turned off or
disabled from the management console of the switch. These protocols may cause the
terminals to start to gain IP late at first power-on or unable to take an IP address on
the network properly.
•If your network contains a Firewall
•Make sure that your network does not have a MAC-Filter.
•Make sure that UDP 65535 port (terminal discover port i.e miFinder Config) should not
be blocked.
•If your device is unable to gain an IP address from the DHCP server, please define or
give freedom to the MAC ID of the terminal in your network (via management console
of firewall, router etc.)
•Make also sure that TCP ports used by the terminal should not be blocked.
