Gigabit (1000Base-SX) issues

Would like to ask some ideas if there's an interoperability issues between a Cat 2948G and Cat 3550 linking using 1000Base-SX port/module with default config only. The two switches will not connect even if it's connected through a 2m fiber SC patchcord only in back-to-back mode.

Looking forward for your great ideas.

Thank you.

Not any known issues I can think of. Try disabling auto-negotiation and see if it makes any difference
