Hi Firewalla Team

Can you provide any recommendations on SFP+ GBICs? If you could provide the make/models that the switches weree tested with that would be awesome!!!

Thanks!

  Anything that works with netgear, tplink, trendnet, ubiquiti should all work with the Firewalla. If you are looking at RJ45, then it's best to stay away from 2.5Gbit and 5Gbit SPF+ RJ45 transceivers.

  I am planning to buy the Switch X. I need a few more than 8 copper Ethernet ports, but not so many that I need two Switch Xs.

  Questions:

  1. Can I use modules like this: FS 1000BASE-T SFP Copper 100m RJ-45 Transceiver to get additional 1G copper Ethernet ports? Is the 10G SFP+ port compatible with a 1G SFP copper Ethernet module? 

  2. If I can use SFP+ to 1G SFP Ethernet modules in the Switch X, can I use 4 SFP copper Ethernet modules, or is there a thermal, power, physical, or other limitation?

  3. If I can use SFP+ to 1G Ethernet modules in the Switch X, will I be able to manage those SFP+ ports in the same way I manage the eight native copper ports?

  1. I suggest not get any single vendor specific (like Cisco compatible) SFP+ modules. I'd look for modules that's compatible with many different brands of switches instead;

  2. Depend on the module, some modules can get hot, so you may get the fan running a bit louder.

  3. Yes
