Ruckus switch ICX 7150 - IP lost after hard reset

[mshrivas]

Hi,

As you asked me to create a new ticket, so here it is. There was a power outrage in my home. After that, the wifi got really slow. Before that, the switch ICX 7150 used to show 'disconnected' in the unleashed dashboard. Also, it didn't have the latest firmware to work with unleased. However, I had ignored it because the wifi was working fine, and I got busy at work.

After the recent power outrage, I went through some topics here and found similar issue raised by members. I tried to fi it myself so I did hard reset on switch because I didn't have login/password credentials and none of the default credentials worked. After the hard reset, the switch has no IP address. I would need your help to configure the switch to its latest firmware, and to be able to connect it in the unleased. I hope after this fix, the wifi should start functioning properly. I have Macbook and no windows laptop to work with.

Thank you,

Thank you for the reply.

The ssh doesn't work. The telnet doesn't work. I do not have a windows laptop, and I'm not going to buy one just for this fix.

Step1:

ssh admin@192.168.1.64

ssh super@192.168.1.64

Error: Unable to negotiate with 192.168.1.64 port 22: no matching key exchange method found. Their offer: diffie-hellman-group14-sha1,diffie-hellman-group1-sha1

Step2:

nano ~/.ssh/config

Host 192.168.1.64

HostKeyAlgorithms +ssh-rsa

PubkeyAcceptedAlgorithms +ssh-rsa

ssh -oHostKeyAlgorithms=+ssh-rsa super@192.168.1.64

ssh -oHostKeyAlgorithms=+ssh-rsa admin@192.168.1.64

Error: Unable to negotiate with 192.168.1.64 port 22: no matching key exchange method found. Their offer: diffie-hellman-group14-sha1,diffie-hellman-group1-sha1

Step3: 

nc 192.168.1.64 23

no output, and no change in the command prompt.

Step4:

I plugged usbc-console cable in mac and switch (console port #15). The usb driver was already installed yesterday.

ls /dev/*usb* --> gives

/dev/cu.usbserial-A9L4QDQB /dev/tty.usbserial-A9L4QDQB

screen /dev/cu.usbserial-A9L4QDQB

or 

screen /dev/tty.usbserial-A9L4QDQB

gives error that sorry could not find a PTY, and it gets terminated.

Somehow, I do not see the silicon lab driver in usb, however, the mac tray icon shows CP210xVCPDriver.

what to do next ?? How do I access the CLI ?

[mshrivas]

I unplugged usbc from mac and re-plugged, and then tried below command from the terminal.

screen /dev/cu.usbserial-A9L4QDQB

This time a blank screen appears. When I press a key, it asked for login/password. I thought USBc-console cable is to bypass the login credentials, but it does ask. At this point, I'm totally lost.

Update: after taking help from ChatGpt, I was able to reset the login/password. 

1. Connect Console

• Plug the USB-C console cable into the switch’s USB-C console port and the other end into your MacBook.

• On macOS, the device will appear as something like: ls /dev/tty.*

• you should see entries like:

   

  /dev/tty.usbserial-XXXXX /dev/tty.debug-console

  The tty.usbserial… is usually the right one

  2. Open Terminal Session

  screen /dev/tty.usbserial-XXXXX 9600

  • Default baud rate for ICX switches is 9600.

    3. Interrupt Boot

    • Power cycle the switch.

    • As soon as you see boot messages, press b (sometimes Ctrl+B depending on bootloader version).
      You should enter the boot monitor (Boot>) prompt.

      4. Reset Password

      From the Boot> prompt:

      • Boot into “fastiron” with password recovery disabled:

         

        no password

        boot

      • Once it loads, you’ll be in privileged mode without a password.

        5. Set New Credentials

        Enter global config mode:

         

        enable

        configure terminal

        username admin password yournewpassword

Save config:

write memory

After this, I was able to login to switch IP. 

I now need your help to upgrade the firmware/routing code for this switch. Thanks.

I have downloaded the firmware zip file from here:
