I want to make sure a design document I'm reviewing is accurate. 

I thought the "FX" a vendor assigned to a switch for our project meant that the switch had fiber optic capabilities (FX - encoding on fiber optic), but the vendor told me that the "FX" solely referred to the PowerEdge FX2 name to which it is connected.

Is the FX2 just a random ID for the PowerEdge server, or is it meant to identify the server as optimal for fiber optic use?

 

Thanks!
