Fibre connectivity issue between ProCurve 4000M (J4121A) & ProCurve 2650 (J4899A):
On the Procurve 4000M (J4121A) switch, I have 1x J4113A SX fibre module
On the Procurve 2650 (J4899A) switch, I have 1 x J4858B SX fibre module
When i connect the 4000M to the 2650 using a fibre patch cable MM SC/LC (62.5) i can't get a link up.
Any ideas why?
I've telnet'ed to both switch and status show everything ok but the link is down.
I know the fibre cable i'm using is working because i'm able to get a link between the Procurve 2650 (J4899A) and another switch that i have Procurve 2524 (J4813A) which has 1 x J4131A sx gig fibre module.
Both switches are using SX modules so i can't work out why i can't get a link.
Thanks for you help in advance
Solved! Go to Solution.

Do you have an SC-SC cable to test the 4000 to 2500? Maybe the 4000 has a problem (it is pretty old) with the module or SX port?

Thanks for your comment. Yes it was the speed settings. I changed the 4000M to auto and now have a link. All working.
Thanks again
