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,

after a long time with the support I got all (4) switches replaced.
With the new switches the problem is gone. Now my stack is working fine.

So for me the problem was the really in the switch not in the modules or cables.

RPS15 is correct for non-POE ICX7450s. RPS16 is correct for POE ICX7450s. The power supply used is not tied to the number of modules you have in the chassis. Are the modules actually online (OK) in 'show module' output?

Could you also send in the first page of the 'show run'?

What is the exact model of optic you are using? Is it Ruckus branded?

The best bet would likely be to open a support case (see my signature) and then one of our engineers can help troubleshoot.

Hi Ben,
thank you for the very fast answer.
I currently have no access to my switches. I will add the Infos tomorrow.
Yes the modules show status online. Green light is on on alle modules. And there are shown in the switch.
Here one info from my documentation.

Sounds good. Below commands would help identifying the optic side of things.

Hi Ben,

One Port is online and one stays offline...
There should be an connection to SW03 1/4/1

I’ve had the same issue, could not find resolution, so stacked with 10G ports.

Hi frnkblk,

Im currently still in contact with the support.
I will let you know if there is anything new.
Currently we ware testing with new, replacement hardware.

Any update or solution here? I have the same issue - for me it is important to stack 40G.
