Maxim,
You would do well to note the caution these good people have expressed about the SX mini-GBICS. By the information you've provided about your mini-GBICs, no one in this forum can answer your question with certainty.
Maybe you could offer up some representative serial numbers. Still, I doubt you will receive a definitive answer.
Why don't you test it yourself and post the results? Be sure to test with different mini-GBIC serial ranges and chassis firmware versions including the most recent.
My post here is final on this topic and more for everyone reading. No Maxim -- I don't work for HP.
