It appears the switch is a 4Gb switch, so although you might insert an 8Gb SFP, it will never work at that speed; switching back to 4, 2 or 1 will probably work just fine as the standard dictates backwards compatibility.

I believe it was stated the switch is 4 Gig and the SFP is 8 Gig if I read it correctly.

I agree with RRR. I don't believe it will work at that higher speed and I don't even know if it will work at 4 Gig. I'd recommend checking with IBM on this though.Thank you.
