Haven't used the SFP ports.
I have had this switch for over 2 years; I liked it so much I went to buy another as it is time to expand and I noticed what little reviews it had, so I thought I should share my experience; This switch does a lot of heavy lifting as it is used to power and transmit from 5MP IP cameras.
I have had a problem where the configuration was lost once; I'm pretty sure I wrote the changes
