Connecting 3508G to Extreme Networks Summit switch

I am trying to connect a stack of GB summit switches to a Cisco 3508G. When I connect the Summit to the 3508, I get a link LED on the Summit, but nothing on the 3508. All the GBICs on the 3508 are known good. Anyone have any experience w/ this sort of thing?

Thanks!

Few things I would check

1)Make sure the GBICs are of same type

2)Disable auto negotiation on both sides. On the XL you can do a "no negotiation auto"

3)What configuration do you have on the XL for this gig interface and what is the corresponding config on the summit switch(is it a access port or a trunk port)

4)Do a sh intergace gig 0/# and see what the status is

Regards,
