Google Multi-Gig Router and Wifi Mesh Tri-Band Extender ports
I just upgraded to Google Fiber 2Gig and there doesn't seem to be much documentation about what each of the ports mean on the two devices that they provided:
I was able to find some FCC documents about each:
I contacted Google Support and got as much info as I could.
Google Multi-Gig Router ports
I have the model number GFRG300. There are 1 RJ-11 port, 5 RJ-45 ports, 1 USB port, and one SFP+ port. Starting from the top:
Green RJ-11 port with phone handset icon: Line for VOIP phone
3 yellow RJ-45 ports with arrow icons: 1 gbps LAN ports. (Ports intended for devices connected to LAN, e.g. PCs, NASes)
Red RJ-45 port with globe icon: Secondary copper WAN connection. Unknown speed. Google Support stated that Router does not support dual WAN uplinks. (Port intended for setups where direct ONT fiber connection is not available and requires a modem and copper RJ-45 for uplink. Not intended for LAN connections. )
Bronze/copper RJ-45 port with the text “10” and arrow icons: 10gbps LAN port. (Port intended for a multi-gig switch or the Wifi Mesh Tri-Band Extender.)
Blue USB port: Intended for tech-support/troubleshooting service. Google Support stated there is no network connectivity supported over USB.
Silver SFP+ port with globe icon: 10gbps SFP port for WAN uplink. Google Support could not provide if this was an SFP or SFP+ port, but it's probably SFP+. (Port intended as uplink using fiber SFP module for connection to ONT.)
Google Wifi Tri-Band Mesh Extender with Wifi 6
I have the model number GFEX310. There are two RJ-45 ports and one USB port on the back of this device.
Going from left to right:
Black USB port: Intended for tech-support/troubleshooting service. Google Support stated there is no network connectivity supported over USB.
Yellow RJ-45 port with arrow icons: 1gbps LAN port (intended for LAN pass thru for wired devices)
Blue RJ-45 port with arrow icons and globe icon: 1gbps LAN port (intended for wired connection to upstream router or switch)
