ICX 7450 40Gig Stacking/Uplinks not possible

[lks]

Hello Ruckus Pack,

I have four 7450 Switches with two 1Port 40Gig Modules installed in the rear slots.
I want to build a stack with all 4 Switches. But when I stack connect them (via 0.5m QSFP+ passive DAC Cable) some ports of the switches are not coming online. the modules and also the cables are being recognised but the port stays down.
I tried it with the FI08095k firmware - then upgraded to the FI09010h_cd2 version. Same problem. Some ports just don't want to come online.

I tried new cables, new modules, completely flashing the switch, reconfiguring it and so on. Nothing helps.

I now have seen that there are installed two of the RPS15-E PowerSupplys
Do I need the RPS16-E with more power to use 3 Modules?

Does anyone have any idea what I can do?
Thank you 🙂

Hi Ben, 
as Im still troubleshooting I found that my ports going to state blocking. 
I want to do a 40 gig ring stack with the four switches. - and have them cabled like that... 

When I want to build the stack I get the infos that the ports need to be online? But how?
I disabled STP on the stacking ports but had no luck
What am I missing?

'Blocking' is a layer 2 status and is irrelevant if the port is down at layer 1, so I would not worry about seeing that status. Is the port defined as a stack port (first part of 'show run')? Are you using stacking interactive setup to stack?

It may be easier to open a support case and have us troubleshoot with you.

That looks good to me. I would advise opening a case so we can formally help you.

Hi Ben, 

just for your info: I tried building the stack with the 10Gig Ports - no Problems. Works like a charm. 
I have an open ticket, if the hardware is the problem. We will see. 

Thanks for your help
