Fortiswitch And SFP's

Last month, I started to update my lab network. The old Juniper EX ‘core’ switch was replaced by a FortiSwitch 108E-POE. The problem was that the Juniper had 14 * 1Gbps interface, and the FortiSwitch only 8, with an additional 2 * SFP Gb ports.

A couple of well known venders ship hardware that won’t allow offbrand (cheaper) SFP’s, but the FortiSwitch has no issues with a mix of vendors. Currently it hold an (ancient) Tippingpoint 1Gbps SFP (RJ45) and a new Ubiquity 1Gbps SPF (RJ45).

I wouldn’t advise this in any production environment, but for a home/dev environment it works (so far) and it’s (much) cheaper. The Ubiquiti SFP was around €25 (retail) here in the Netherlands, which is about a fifth of the official Fortinet SFP price.
