I bought a BATM (Telco Systems) T5C (CN) 48 port switch recently and it has two Mini-GBIC slots for Gigabit ethernet, etc. My main questions are: Can these be used to link into a server using fiber for a Gbit uplink? Are the Mini-GBIC SFP units interchangeable between manufacturers? (I can't find one made by BATM so I'm hoping a generic, IBM, 3com, Cisco or HP one will work) Will other manufacturers Mini-GBIC SFP to Copper Gbit adapter possibly work on this unit? (This is my biggest hope as it will be the easiest and eliminate my need to mess with the fiber stuff completely!) What kind of cabling and NIC is needed on the server end? (I'm a network n00b and I'm trying to learn on my own.) I will probably get equipment from ebay to mess with this thing, I just would like some advice so I don't waste too much money. Like I haven't already if you ask my wife! Also, after a few convos on Anandtech, I'm thinking it may be best just to sell this unit off and get one with built in copper gbit ethernet ports. This would be MUCH easier and probably more cost effective in the long run. Given the fact that the SFP copper units are skyrocketing on ebay for well over $100 each, and I can get another switch for about that price alone I'll probably have to buck up and just buy one with built in copper.
