Comcast Connection Pro Failover GS324TP EERO

I'm using comcast business class Internet modem connected to an EERO in my office.  The EERO grabs comcast cable modem connection (static ip) and acts as a DHCP server both over Wifi and Through my netgear switch.  This seems to work great.  I get Wifi and wired devices working great.  No problems.

 

But now Comcast has given me a backup LTE modem for situations where there is cable problems.  I would like to utilize this modem in a fail-over type of way to make it switch connections automatically.    See the attached rudimentary diagram.  The Comcast tech said I just need to set up one port to switch to if it detects no internet on the comcast modem.  

 

Can someone walk me through how to set this up?  Do I need to configure the whole system differently?

 

Thanks in advance.

    Not really a switch problem - much more a question to talk to Comcast Business services and on how to integrate this LTE Backup device in combination with a modem and a 3rd party router like your EERO.

     

    It's unclear to me if this unknown and undefined failover device should reside on the LAN or on the WAN/Internet network (between modem and router Internet/WAN port).

     

    Browsed around some pages on the Comcast Business support about the Connection Pro, but was not able to find much beyond of the need to enable the device/sevice on the portal.
