ICX 7150 stops working after power outage

[rahulmunjal]

I have a Rukus and two APs and every time there is an electricity trip the Rukus switch fails to connect to the internet and it just goes into an intermediate state where the devices keep connecting gf and disconnecting. All my devices like garage door, ring bell, switches, etc which use WiFi stop connecting. It takes a hell lot of multiple reboots of all modem, router, and switch and wait and watching for several hours or even days to stabilize the connection. I did check that the AP is on latest update but have no access to the switch itself to check the firmware version and upgrade. I see steps to connect via putty on windows but I do not have any windows machine at home (just iPads and Mac). This has been happening for about a year and I end up connecting directly to modem/router for my office work when I have to. Need help urgently to fix this situation. Thank you in advance. Let me know if any additional information is needed to understand and fix the issue.

Hi Rahul,

Thank you for reaching out with your query!

I understand that you are using a Ruckus ICX switch along with two access points (APs) to provide Wi-Fi for your smart devices, such as your Ring, garage door, lights, and switches.

You've reported that after any power outage, the switch fails to reconnect to the internet, which puts the APs and Wi-Fi devices in a cycle of connecting and disconnecting. This issue can take hours or even days to resolve, often forcing you to bypass the switch and connect directly to your modem/router for work.

You confirmed that your APs are up to date. However, you cannot access the switch firmware version, which may be outdated. Since you only have a Mac or iPad and no Windows PC, you haven't been able to use PuTTY to check or upgrade the switch.

To access the switch using your Mac, please refer to the following link:

If the switch is stuck in a boot loop, we can perform a software recovery. You can find the instructions here:

Thank you for getting back quickly. I tried to connect using CLI on my mac; was able to identify the IP of my switch through Unleashed as well as the Fing app. But when I try to SSH using Super or Admin as instructed, I receive an error on terminal.

Last login: Fri Aug 22 22:50:14 on console

% ssh admin@192.168.0.24

Unable to negotiate with 192.168.0.24 port 22: no matching key exchange method found. Their offer: diffie-hellman-group14-sha1,diffie-hellman-group1-sha1

% ssh super@192.168.0.24

Unable to negotiate with 192.168.0.24 port 22: no matching key exchange method found. Their offer: diffie-hellman-group14-sha1,diffie-hellman-group1-sha1

What should be the next step? Please suggest.

FYI - I have also tried

ssh-keygen -R

% ssh-keygen -R 192.168.0.24

Cannot stat /Users/xxx/.ssh/known_hosts: No such file or directory

Telnet just does not show the prompt either... although no error is displayed.

% nc 192.168.0.24 23

% nc 192.168.0.24 23

What should be the next step I can try??
