ICX-6450-24 10G SFP+ not working?

Hi,

We just bought 2 ICX6450 and a (according to the manual) fully supported 10G-SFPP-TWX-0101 10G twinax cable to stack them. I am new on Brocade ethernet switches (we have some of their SAN switches though) and I am having issues with the stacking ports. 1/2/1 and 1/2/3 are 10G and enabled. 1/2/2 and 1/2/4 are 1G as we did not get the additional license. I set them to 1G and disabled them, as I was unable to disable them when on 10G. The SFP+ insertion is detected on both switches:

Port 1/2/1 optics inserted, wait for Phy port initialization...

And then nothing. No matter what I do I cannot get a link in order to build a stack. I don't have another SFP+ cable at hand to test, I am starting to believe the cable is no good, but as I am new to Brocade I'll post my configs. I assume when plugging in the TwinAx cable I should at least get a link when the port is enabled?

Both switches have the same config. although I tried with the stack disabled on the second switch as well but secure-setup was unable to find the second switch.

58-1000026-01 is the exact partnumber on the label of my cable, although the modelnumber is 10G-SFFP-TWX-0101.

Re: ICX-6450-24 10G SFP+ not working?

if you have this part number then you have the right cable.

is probable the cable is defective, or you have made wrong settings.

I'm not familiarly with IP Plattforms, and don't know all the command, but you can looking for Port disable / enable, or review the config.

I've replaced the twinax cable with a Cisco twinax cable we had lying around (actually I used 2 of them now to create a ring) and it immediately worked. The brocade cable just seems to be defective. Thanks for your responses
