ICX7150-C12P stuck in boot loop after power outage — can't hold a stable boot prompt

TommyLas — Wed, 08 Jul 2026 22:07:53 GMT

Hi, I'm a Lennar homeowner and my pre-installed Ruckus ICX7150-C12P is stuck in boot mode after a power outage corrupted the flash image. Hoping for some help.

Boot output (same every time):
- Bootloader loads fine: Ruckus Wireless Bootloader 10.1.15T225 (Jan 30 2019)
- Hardware: ICX7150-12 (POE), PVT1, SYS CPLD VER 0x4, Released Ver 0xa
- Primary fails: "NAND read from offset 0 failed -22" → "Bad FIT kernel image format!" → "ERROR: can't get kernel image!"
- Falls back to Secondary, fails the same way: "NAND read from offset 4000000 failed -22"
- ECC read errors on both partitions before each failure (iproc_nand_read_page returned 2, multiple ecc_errors)
- Then drops to ICX7150-Boot>

My setup:
- Mac connected to the USB-C console port
- Silicon Labs CP210x driver installed, device is /dev/tty.SLAB_USBtoUART
- 9600 baud (tried both screen and picocom)

The problem I'm stuck on:
I can reach ICX7150-Boot>, but it won't stay stable. Right after the prompt appears, the console starts receiving fragments of the switch's own boot banner ("23:08OK", "ICX7150-12 (POE), PVT1", "SYS CPLD VER: 0x4"), which get read as commands ("Unknown command..."), and it snowballs into a continuous self-repeating loop that makes the prompt unusable. This happens identically with local echo turned off and across different terminal programs, so it doesn't seem to be a terminal echo issue on my end. The "Enter 'b' to stop at boot monitor" countdown shows 0, so there's basically no window to interrupt autoboot.

What I've already tried:
- Multiple USB ports/cables, reseating, hubs
- screen and picocom with echo and flow control disabled
- Pre-streaming 'b' before power-on to try to catch the zero-delay boot window

Questions:
1. How do I get and hold a stable ICX7150-Boot> prompt given the near-zero bootdelay and this self-echo loop on the USB-C console?
2. I have the recovery boot code (mnz10115.bin), recovery image (SPS08090k.bin), and final image (SPS08095sufi.bin) ready for a TFTP recovery — can someone confirm the correct procedure for this unit?
3. Given the ECC errors on both partitions, is this recoverable via software, or does it point to a NAND hardware failure needing an RMA?

Confirming this is a Ruckus setup in a Lennar home. Thanks in advance for any help.

Hi Sofia, I was able to get SYST and PWR to green following all instructions.
I have 2 access points on the ceiling.
One with 5g and 2.4g lights as orange, and PWR as green.
Another one with all off except the PWR as green.
Could you assist me with more information on how to set these up and make sure they are working?
Thank you Sofia!

Hello @TommyLas

Please check the following link:

On the APs, the only LED that should be off is the "AIR" indicator.

If, after completing the software recovery, you are able to connect to the APs and access the internet successfully, it indicates that the network is functioning as expected.
