RMA Request - Defective Hardware - Powers on but causes broadcast storm

laxdan

Not really a question for the community, but regular Ruckus support told me I had to post here and get a response from a "Support Engineer" to get an RMA request 🤷. Bit odd, but here it is:

Lennar Smart Home system installed w/ my home. Unit is an ICX 7150-C12P w/ 2x APs connected to it. Also has all the wall sockets from the house connected to it.

The switch boots but seems to be causing a broadcast storm (network speeds drop, the network becomes unstable, and then typically drops traffic completely. Occasionally reboots itself) shortly after power on. Rebooting it resolves the issue temporarily, but it typically takes the network down again after a few minutes.

Unit has been factory reset multiple times, but problem persists. The problem still occurs after switching the APs (and other connected devices) to different ports. Network is unusable while the device is powered on and connected.

Replacing the switch with a cheap unmanaged PoE switch has resolved the issue. All the same devices are connected, so this unit likely has faulty hardware.

Just trying to claim the lifetime warranty on the switch, so hopefully a support engineer can approve this. Thanks!

Hi @laxdan,

Thank you for posting, based on the issue description, it seems your switch is experiencing a known-issue.

Here the guide that describes the problem and explains how to fix it:

Fixing RUCKUS ICX-7150-C12P Switch Routing Code (SPR) issue using Command Line Interface (CLI)

Let me know how it goes and if you have any questions.

Hi @laxdan

Greetings!!!

I trust this message finds you well.

I kindly request an update on the status of the issue so that we may proceed further with resolving it.

Thank you.

Hi Maria,

Still working on it. It won't boot anymore and gets stuck during the factory reset process (the amber lights start flashing, but it never stops, even when left for 10-20 mins). I've left it running overnight to see if it will eventually recover.

I tried working on this software recovery procedure:

https://community.ruckuswireless.com/discussion/47483/how-to-perform-a-software-recovery-on-an-icx7150-switch

But my USB-C → ethernet adapter can't seem to get a link with the OOB port and the serial connection breaks if I try to run network + USB Serial over my other combo adapter (has USB ports and an ethernet adapter). I'm going to borrow an ethernet adapter from work tomorrow and see if that works.

It's stuck on ICX-BOOT> when I connect via console right now, but I'll try the suggestions above, if I can get the switch to boot properly.

Thank you for the update, let us know if you have any questions.

We are here to help!

Okay, so the factory reset eventually worked and I confirmed that it's in router mode:

But when I try to follow the instructions to set it to SPS mode:

I figured this might be a corrupted firmware issue and started following the upgrade instructions here: https://support.ruckuswireless.com/articles/000015159

But it turns out it's not an issue with my adapter. I tried multiple different USB adapters + cables, as well as multiple different USB-C to ethernet adapters, but I can't get a link established between the switch and my laptop so I can't follow the rest of the article. I tried connecting other devices to it, just to see if they would establish a link, but one indicator light goes green but no flashing lights or indicator light on the other side.

Additionally, the serial connection seems to go haywire anytime I plug anything into any of the ethernet ports. If I reboot the switch and connect via USB only, I can access the console and run commands normally. But as soon as I connect anything to an ethernet port, my console window goes wild and starts generating garbage:

It did something similar yesterday:

So I think I might be stumped here, unless there's a way to flash the firmware over serial without using a TFTP server?

Hi @laxdan

Thank you for your efforts troubleshooting this unit.

For the upgrade we don't need to go into boot mode, I'm not sure why the last image shows boot mode.

Once you get the switch to boot up completely, login and enter show version, there we need to enter the copy command to load the new (UFI firmware).

You are seeing this error: "Unable to find an UFI image to copy from" because your command refers to an .ufi file and the switch, actually, has 2 different issues. Let me explain…

The SPR code is one of them.

And the second issue is the fact that the current software image is not UFI, per this warning message:

WARNING: FI image is not booted from UFI!!!      =============== ======  Please download UFI image and reboot the system for full functionality  ======

Based on this logic, we cannot fix issue 1 until issue 2 is fixed. But we will fix both in one upgrade, using the USB method.

Please get a USB flash drive, make sure is formatted as FAT32 and connect it to your computer.

Here the rest of instructions

Here some additional instructions that will adapt the above guide to your specific scenario:)

From the article shared please start at step B.

Skip step F (we don't need to do this because your switch is on a version higher than 8080f)

On step G, we will only look at the 1st point, then follow these instructions:

G.1: copy disk0 flash SPS08095gufi.bin secondary

Then:

show flash (Here we expect to see SPS08095gufi on the secondary partition, if you see any weird symbols or "empty" let me know)

copy disk0 flash SPS08095gufi.bin primary

write mem

—> Disconnect the USB from the switch please!

reload

yes

—> Wait until the unit reboots, login and use show version to see if it shows as SPS08095gufi

The warning should be gone too, that should fix all the switch issues.

Let me know how it goes and if you have any questions.

laxdan

Okay, that procedure seems to have worked! The switch already seems to be working better (booted up way faster, didn't get stuck in boot mode, etc)

Hi @laxdan

Thank you for the update. I'm glad to hear the upgrade went well. The logs* certainly look good.

Is it ok if we mark the thread as resolved by Monday in case we don't hear back from you?
