After power outage network is dropping - Switch showing disconnected state

New Contributor II

Hi, I am in a recently bought Lennar home which came with a ICX7150 switch with two access points. I have 1gbps fiber connection and it was all working great till I had a power outage and the switch rebooted. Since then my network is terrible. I searched the forum and similar issues reported and the solution seems to be to get the switch to boot up with switch firmware. I logged into the switch console (it says unleashed) and it is showing internet is connected however switch is in disconnected state.

I connected to the switch to the usbc port and was able to see the boot up sequence. Below are the messages

device 0 offset 0x0, size 0xc0000
BOOTING image from Primary

NAND read: device 0 offset 0x0, size 0x2000000
5 ecc_errors after reading 1b48000:1b49c00
iproc_nand_read_page returned 2
NAND read from offset 0 failed -22
0 bytes read: ERROR
## Loading kernel from FIT Image at 70000200 ...
Bad FIT kernel image format!
ERROR: can't get kernel image!
could not boot from primary, no valid image; trying to boot from secondary
device 0 offset 0x0, size 0xc0000
BOOTING image from Secondary

It is booting from secondary using the image SPR0809d.bin which I think is the router image while I need the switch image to solve the problem. Booting from secondary image it is asking me for login / password which I do not have. I will try the ones provided in the below post -

I attempted to tftp the switch image into primary partition, however the switch does not seem to able to ping the tftp server. I am on Windows 10 laptop using Solarwinds tftp server.

Here are my questions.

1. Is there a way to reset the login / password for the secondary partition ? I interrupted the boot sequence by pressing b and that is getting me to a ICX7150-Boot prompt.

2. Though the error is saying "ERROR: can't get kernel image! could not boot from primary, no valid image;" I am assuming the switch firmware needs to be loaded into primary partition. Am I missing anything ?

3. If I cannot get switch to reach my tftp server (running on windows 10) how do I flash the switch firmware to primary partition? Are there any other options I can try ?

I am very much stuck at this point looking for help. This clearly is not for an average home owner and requires specialized skills.  I have been trying to resolve this for weeks now and it is very frustrating Lennar or Ruckus does not offer any support besides this forum. I think these type of issues could be resolved quickly if phone support is provided. Thank you!




HI @pi 

If the Switch is booting from the secondary partitions it will be a matter of booting from the primary, so try the same process but via web access, with the IP address you already know for the Switch, let me add the guide, once we solve that problem you can update the Switch from the Unleashed site locally, now sometimes it happens that the credential happens to be the ones you use to login to Unleashed APP, try with those if not I will also pass you the guide to change the password however it must be by console as you were before.

1:Find the Switch IP address:

How to find my Ruckus “Devices IP address” using free applications

2:Follow up the next guide, try the credentials you know for the Unleashed APP or not the next bundle(user always will be lower case super or admin)

Usernames:           Passwords:

admin                    sp-admin

super                     Lennar







How to Fix Routing code issues on Lennar Home users via Web GUI.

3:If the credentials are not working, gain access back via console and follow up the next steps:

Password Recovery on a Ruckus ICX(Tutorial video)

Recovering from a lost password (CommScope Guide)

4:Like you gained access after the password recovery, run the next commands to fix the routing code issue.


ICX7150-C12 Router>enable   

ICX7150-C12 Router>show flash  (you can confirm in which partition you have the correct code that will start with SPS example: SPS08080f.bin normally will be your primary partition)

ICX7150-C12 Router#copy flash flash secondary  (this will copy what is in your primary code to the secondary)

ICX7150-C12 Router# write memory

ICX7150-C12 Router#show flash  (now both partitions must start with the SPS before the code type)

ICX7150-C12 Router#Boot system flash primary yes

Hi Yarenis, Thank you for the quick response. As you can see from the boot log messages in my post, I cannot boot from primary due as there is no valid image. See below errors.

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

I know the ip for the switch and when I login through the browser, it is showing me Unleashed Dashboard. While I am able to login to the Unleashed web GUI from browser, the same user / password are not working when I connect directly to the usbc port. I will try your suggestions to reset the password. The device is booting from secondary only since primary does not have a valid image. The secondary partition has router image.  So, I believe I will need to upload the switch firmware to primary to get my problem resolved?

Hi @pi 

Correct, if you can boot from secondary partition you can perform an upgrade from there, I will advise you to perform the upgrade for both partitions you can use the USB option, let me add the guide, if you have any error please share the screenshot here.

Note: you can use the code 08095g, which is the current-recommended code.

Hi Yarenis,

I did not get to resetting the password yet and will let you know if I run into issues there. Meanwhile, have a couple of questions.

1. The UI I am getting through browser when I open the ip address of the device seems to be Ruckus unleashed dashboard UI and not the Web management UI. This is showing me switch is disconnected (see attached image) 

How do I get the "Monitor on the left" ui shown in step 3 in your link -

2. When I ssh into the device, I am getting a Ruckus unleashed CLI prompt (See below image). How do I get the ICX7150-C12 Switch prompt that is shown in this link to upgrade using usb stick -

Thank you!
