Sean,
You just hijacked an 18 month old thread about an unrelated subject! In order to have the best chance of getting an answer to your question, you should probably start a new thread on your subject.
Having said that, the switch model in the subject of this thread is an SF300 switch, which is only a 10/100 switch, so the answer is probably "no". Perhaps the SG300 switches, which are gigabit switches, might support what you are looking for.
Tom
