Hey, Yourguide32,    For the MX64, you will just need to manually configure the "LAN 4" port as a secondary Internet/WAN port. To do this, you will need to sign in to the local status page (http://setup.meraki.com) and toggle the LAN4 port from LAN to Internet, through Uplink configuration under the Local status tab. These steps are also outlined on the MX64 installation guide here: https://documentation.meraki.com/MX/Installation_Guides/MX64_Installation_Guide   The configuration process on the MG21 itself is very simply; you just need to install the nano sim card from your cellular carrier, claim to your dashboard, add it to an active network and then physically connect to your MX and power (AC adapter or PoE injector). Full installation guide can be found here: https://documentation.meraki.com/MG/MG21%2F%2FMG21E_Installation_Guide   Hope that helps! ... View more

Hey @Netwow - none of the MX models have PoE enabled WAN ports; you would either want to use a PoE injector (SKU: MA-INJ-4-US) or AC adapter (SKU: MA-PWR-30W-US) to power the MG21. (if not located in the U.S., replace "US" with "EU", "AU", "UK" etc.) Source: https://documentation.meraki.com/Wireless_WAN/MG21%2F%2F21E_Datasheet ... View more
