I have a CRS504-4XQ-IN and it refuses to auto-negotiate network speed.

It has been powered off for about 4 months or so. I powered it up a few days ago and it would not auto-neg. I updated it to 7.13.2 Stable and still no luck.

I have the 504 connected to 3x Mellanox 25GB cards and 1x CRS326-24G-2S+RM using a XQ+BC0003-XS+ breakout cable and if the 504 is set to auto negotiate, there is no connectivity -- no link light, nothing. I swapped the XQ+BC0003-XS+ with another XQ+BC0003-XS+ cable (I have 2) and the same thing happens. If I force the connection speed manually on the 504 (25GB CR to the cards and 10GB CR to the CRS326), then everything works fine.

Of course I tried all ports on the 504 and there is no link light unless I manually set the speed.

Any ideas?
