Problem with Gig Link not coming up

I thought the Gig connection needed to be FORCED to work. Did you try that?

In my reading of postings, the majority of people I would tend to trust have said that Gig -must- be autonegotiate according to the standards. I have, though, also seen reputable people advise to force gig connections.

My conclusion from reading those messages is that either -some- gig devices are not fully standards compliant, or else that the standards left something ambiguous even though they tried to eliminate the ambiguities.

Update on this: The link did come up and the problem was that the Transmit signal Amplitude was very high. So I lowered the Tx signal amplitude from my Device and the link came up. What was happening previously was that the Link was coming up but after 20 mins or so. But if I used a longer cable then the signal was getting attentuated and link used to come up faster.

From this I concluded that the Auto Nego Link code words signals were getting distorted and the the link partner was not able to decode this. So I reduced the Transmit Signal amplitude from my device and link comes up right away.I need to test it though with different cable lengths. Kott
