Hello - I am using a Intel 82540EM Gig controller with 1 copper Port on my PC (PCI slot) . I have connected this Gig Port to my device(Broadcom) which has Gig Copper Interface and the Link does not come up.
My settings are Auto Nego 1000Mbs FDX on both sides. I have observed the MII Status Registers on my device (Broadcom ) and it shows Auto Nego not completed/Error. Since I have no control on the Intel Side, wondering what could be the problem . Two possibilities are
- MDI/MDIX Crossover is not happening
- Master/Slave Resolution is not hapenning and it is getting to a deadlock
The other observation is that when I connect two of my devices back to back the Gig Copper link is coming up.
any comments from the gurus out there
Thanks Kott
