Ruckus CX7150 Switch won't boot from Primary, boots from Secondary router mode

Lewthound — Wed, 16 Jul 2025 16:08:07 GMT

I had a power outage yesterday and when the system came back up the Ruckus ICX7150 was showing intermittent internet connectivity, and I am unable to connect to it using the Unleashed app on my phone. When I console in with putty, I see this prompt "ICX7150-C12-Router", which indicates that it is in router mode. I attempted to reboot the Ruckus ICX7150 from the Primary, using the command "boot system flash primary yes" but during the boot process I see the error message "could not boot from primary, no valid image; trying to boot from secondary". Any assistance on how to proceed would be greatly appreciated.

Hi @Lewthound ,

Greetings!

Thank you for contacting RUCKUS Lennar Home Community.

I hope you are doing well!!!

Thank you for the information you shared.

From the case description, I understand that you are facing intermittent connectivity issues with your APs after the power outage.

This issue is because your switch is running on the Routing code (SPR). The Switch should run on the Switching code (SPS) for Lennar home users. Due to a power outage/power spike, the Switch boots up on the other partition which may be running on a ‘Routing Code’ results in causing this issue.

Please follow the below RUCKUS Lennar Knowledge base self-help article which will help you to fix the issue when the Switch is running in the Routing code.

Please follow the process as explained in the article and let me know if you have any queries in this regard.

I have read the self-help article you provided, but I need a bit more clarification. I access the Ruckus box via a laptop with a usb C cable using putty. Seeing as when I attempted to reboot the device from the primary using ICX7150-C12-Router#boot system flash primary yes, during bootup, the unit gives the error shown in the log snippet at the bottom of this reply. So, just to confirm, using the following steps in the self-help article are applicable in my situation. Please let me know if you need any additional information.

Solution:
If there is a similar output with SPR, please Enter the below commands in CLI to fix this issue:
Note: Hit Enter to accept each command

ICX7150-12P Router#enable

ICX7150-12P Router#copy flash flash secondary

ICX7150-12P Router#boot system flash secondary yes

Hello @Lewthound ,

Thank you for the response.

I understand you're seeing an error stating that the system cannot boot from the primary image due to "no valid image found." This usually means the primary boot image is either missing or corrupted.

To confirm this, please run the following command in your CLI through PuTTY.

Please enter the below commands once you log in to CLI and share the output.

Note: Hit Enter to accept each command

enable

show version

show flash

Please share the output of the above commands or share the screenshots if stuck at any step or error (if any) and let me know if you have any queries in this regard.

Thank you again. We appreciate your patience and understanding.

Seeing as how my ICX7150-12P won't boot from primary because it says that there is no valid image and it boots off the secondary, do I need to perform a software recovery as outlined in the self-help article below.

RUCKUS Forums - How to perform a Software recovery on an ICX7150 s... - CommScope RUCKUS Community Forums

using the compressed the file "08090k.zip" downloaded from the following link?

Here are the requested pictures. I hope these will suffice, the switch is mounted in a data closet, facing down, so getting good pictures can be difficult. Let me know if you need any additional information.

Hello @Lewthound ,

Thank you for the response.

From the pictures you shared, it seems like the ethernet cable which is coming from the ISP’s (Internet Service Provider’s) Router or Modem/Router combo is plugged into the wrong port on the Switch panel. It must be plugged into any 1 in-12 ports as shown in the below screenshot.

1. Please unplug the ethernet cable and plug it into the correct port then reboot (unplug and plug from the power outlet) and try to connect to the Internet via Access Points.

It should be plugged into one of the 12 ports as shown in the below screenshot.

Please check and let me know if you have any queries in this regard.

Thank you again for your patience and understanding.

Best regards,

Re: Ruckus CX7150 Switch won't boot from Primary, boots from Secondary router mode

Lewthound — Fri, 18 Jul 2025 21:55:08 GMT

First, let me say, I have lived here for 5 years, and the cable you want moved has been plugged into that RJ-45 uplink port since the tech set the ICX 7150-C12P for me when I moved in. My original ISP was Xfinity and the other end of the uplink cable was plugged into my cable modem/router. In May, I switched ISPs and the cable was moved from the cable modem to the ISPs router. The end plugged into the RJ-45 uplink port never moved. Everything has work flawlessly until the power outage, since then the Ruckus box hasn’t worked as expected.

Having read through several related posts on the “RUCKUS-Support-for-Lennar-Homes”, when I putty into the ICX 7150-C12P and see the prompt “ICX7150-C12-Router>”, that indicates that the Ruckus box is running Routing code (SPR). The command “show version” confirms that it is using “SPR08080d”. Comments in the forums indicate that the switch should run on the Switching code (SPS) to avoid Routing Code issue for Lennar home users.

Using the”show flash” command indicates that I have the following codes

Compressed Pri Code size = 25968884, Version:08.0.80dT211 (SPS08080d.bin) Compressed Sec Code size = 29819448, Version:08.0.80dT213 (SPR08080d.bin)

But, when my ICX7150-C12 reboots, I get the errors below and the unit boots into Routing code, which, based on what I have read here, is a problem

“Bad FIT kernel image format!” “ERROR: can't get kernel image!” “could not boot from primary, no valid image; trying to boot from secondary”

With all that said, I moved the cable you requested from the RJ-45 uplink port to a RJ-45 downlink port. This is shown below, along with a picture of the access point.

I can now connect to using the Unleashed app; however, the app doesn't see any switches and anything connecting to the access point's Wi-Fi cannot get to the internet. My phone was connected to the access point, and I had to turn off Wi-Fi to get to the internet.

So, what are our next steps to try and resolve this/these issues? The boot errors and the running of Routing code seems to be a problem that needs to be addressed. But I only know what I have gleaned from reading these forums. If you need any additional information, please let me know. Also, I appreciate your time and attention in helping to resolve this matter.

Hello @Lewthound ,

Thank you for the response.

I understand that you have connected the Switch using the console access.

Could you please try accessing the Switch CLI using the IP address through Putty option?

Please follow the below steps and help us with the queries,

1) To check this, we must identify the ‘current’ IP address assigned by your local router to the switch ICX-7150-C12P

I will leave you a guide on how to perform an IP scanner on your local network to identify the switch IP address very easily.

How to find the IP Address of the RUCKUS Devices (Switch and APs) using IP Scanner free applications:

https://community.ruckuswireless.com/t5/RUCKUS-Lennar-Support-Knowledge/How-to-find-the-IP-Address-of-the-RUCKUS-Devices-Switch-and-APs/ta-p/77863

2. Once we identify the IP address of the switch proceed to access remotely to the device “Command Line”

https://community.ruckuswireless.com/t5/RUCKUS-Lennar-Support-Knowledge/How-to-access-the-Command-Line-Interface-CLI-of-the-RUCKUS-ICX/ta-p/74450

If you can access the Command line should look like this:

ICX7150-C12 Router> OR

ICX7150-C12 Switch>

Please enter the below commands once you log in to CLI and share the output.

Note: Hit Enter to accept each command

enable

show version

show flash

Please share the output of the above commands or share the screenshots if stuck at any step or error (if any) and let me know if you have any queries in this regard.

Thank you again. We appreciate your patience and understanding.

Re: Ruckus CX7150 Switch won't boot from Primary, boots from Secondary router mode

Lewthound — Mon, 21 Jul 2025 20:40:38 GMT

I have resolved the issue of my ICX7150-C12 running Router code. I used the self-help article you recommended, from the RUCKUS Lennar Knowledge base linked below

https://community.ruckuswireless.com/t5/RUCKUS-Lennar-Support-Knowledge/Fixing-RUCKUS-ICX-7150-C12P-Switch-Routing-Code-SPR-issue-using/ta-p/71538

After following those instructions, I rebooted the unit and saw that the ICX7150-C12 is now running Switch code, I confirmed this with the “show version” and “show flash” commands.

I now can connect to the access point with the Unleashed app as well as from my PC and devices plugged into ICX7150-C12 can access the Internet. I appreciate your assistance is resolving this issue.
