RMA approval icx 751

RMA for a replacement unit under the manufacturer's warranty

I’m Jose Gabriel Contreras a Lennar homeowner, and this device is installed at my primary residence which I purchased from Lennar.
I am reaching out to report a critical hardware failure on my ICX 7150-C12P switch (Serial Number: FEK3845Q2E5). The unit now displays a solid amber SYST LED and has completely lost PoE power and data connectivity. After carrying out a thorough diagnostic using the Serial Console (CLI), I have determined that the internal NAND flash memory is physically defective and cannot be recovered via software.

Here are the main technical findings, both PuTTY logs and the status LEDs as evidence:
- Multiple physical bad blocks were detected using the `nand bad` command at addresses 0b400000 and 0b600000.
- Attempts to boot from either the primary or secondary partition consistently result in ECC read errors and a NAND read failure (-22).
- The system is unable to load the operating system and returns a "Bad FIT kernel image format" error, which points to physical memory corruption.

Given that the device is in a non-functional state due to hardware-level memory defects, I kindly request a formal RMA for a replacement unit under the manufacturer's warranty.

Dear Ruckus Support Team,

Im a Home Lennar Owner and this is my primary house.

using the Serial Console (CLI), I have determined that the internal NAND flash memory is physically defective and cannot be recovered via software

Technical Findings (See Attached Screenshots):

· NAND Bad Blocks: The command nand bad reveals multiple physical bad blocks at addresses 0b400000 and 0b600000.

· ECC Read Errors: Attempting to boot from either the primary or secondary partition results in ecc_errors and a NAND read failure -22.

· Kernel Corruption: The system is unable to load the operating system, returning a "Bad FIT kernel image format" error due to the physical memory corruption.

Device Information:

· Model: ICX 7150-C12P

· Serial Number: FEK3845Q2E5

The device is in a non-functional state and cannot be recovered via software due to these hardware-level memory defects. I request a formal RMA for a replacement unit under the manufacturer's warranty.

I have attached the PuTTY logs and photos of the status LEDs as evidence. I look forward to your prompt response with the next steps for the replacement.
