After power outage network is dropping - Switch showing disconnected state

[pi]

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

ICX7150-Boot>boot
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

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 

1-That is done by default since the switch get ip from your local gateway has dhcp client is enabled, so it tries to look also  for a TFTP configuration.

We can try the following command below:

ICX7150-48ZP Router>enable
ICX7150-48ZP Router#configure terminal
ICX7150-48ZP Router(config)#tftp disable

So if that doesn't work, we need to do a static setup which we don't recommend for Lennar home users.

2-The main function of the switch is to provide wired connectivity and PoE to the APs so does not affect anything related to the configuration of APs

3-Thats correct we can give a try to the instructions that  I listed !  Also this is correct: Adding the switch from unleashed dashboard is asking me for a admin user and password and all I need is those credentials.

I'm having precisely the same issue. 😑, I called Ruckes they hung up (or the call disconnected) on me twice.. they don't deal with Lennar homes anymore.
