I have an Extreme X450-G2-48P-GE4 which I am linking to a Cisco 3750 series switch using two Cisco SFP 1000base SX modules (GLC-SX-MM). I am running ExtremeXOS version 188.8.131.52. I have no link lights, and no errors in my logs.
When I pull a debug on the port it shows signal is present, but that there is a "TX fault". I have tried increasing the debounce to 150 and then to 900, and rebooted the switch several times --- but still no connection.
Does anyone have any ideas on what I can try? I have two Extreme brand SFP's on the way, but I am trying to get this connection up in a hurry as users are anxious to get into new office space.

[/code]Also, I am *assuming* that the physical cable is good. But I had better be sure that it's not before I have the company come out to run a new line.
