Limited/No internet since brief power outage

bbradley01

I have a Lennar home with a Ruckus ICX 7150-C12P Switch and 2 R510 aps.

A week ago we had a brief interruption in power (5-10 seconds). Since then, our wireless internet is barely working and most of the time is not working at all. I have looked through the forum and switched the boot sequence but that did not work. I hard reset the aps and switch, deleted and reinstalled the wifi networks through the unleashed app and still have not found a solution. In the unleashed app it shows the APs as connected and broadcasting wifi but the switch is 'disconnected'.

The internet is working perfectly fine through my internet provider.

Any ideas on how to fix this?

Thanks!

Hi @bbradley01

Thank you for the response and the information you shared.

As discussed earlier, this issue is because your switch is running on the Routing code (SPR). The Switch should run on the Switching code (SPS) to avoid these issues for Lennar home users. Due to a power outage/power spike, the Switch boots up on the other partition which may be running on a ‘Routing Code’ results in causing this issue.

As I can see from the output you shared, your Switch is booted up on the secondary partition which is running on Routing code (SPR) as highlighted in the below screenshot.

Please Enter the below commands in CLI to fix this issue:

Note: Hit Enter to accept each command

enable

copy flash flash secondary

boot system flash secondary yes

Example:

ICX7150-24P Router>enable (hit enter to accept the command)
ICX7150-24P Router#copy flash flash secondary (hit enter to accept the command and wait: until the flash finished)
ICX7150-24P Router#boot system flash secondary yes (hit enter to accept the command: the switch will reboot)

After the above process, the issue should be fixed.

NOTE: Please feel free to mark the post as ACCEPTED SOLUTIONS.

Please let me know if you have any queries in this regard.

Thank you again for your patience and understanding.

Hi @bbradley01

Greetings!!!

Thank you for contacting Lennar Home Community.

Hope you are doing well!!!

Thank you for the detailed information you shared.

As per the case description, I could understand that your RUCKUS setup is not working after a brief power outage.

This issue may happen when the Switch runs on the Routing code (SPR). The Switch should run on the Switching code (SPS) to avoid these issues for Lennar home users. If the Switch boots up on the other partition (Due to a power outage/power spike) which may be running on a ‘Routing Code’ results in causing this issue. To check the same please follow the below process.

Please follow the below steps and help us with the queries,

1. To check this issue, we must identify the ‘current’ IP address assigned by your local router to the switch ICX-7150-C12P

I will leave you a guide on how to perform an IP scanner on your local network to identify the switch IP address very easily.

How to find my Ruckus “Devices IP address” using free applications:

https://community.ruckuswireless.com/t5/RUCKUS-Support-for-Lennar-Homes/How-to-find-my-Ruckus-Devices-IP-address-using-free-applications/td-p/47027

2. Once we identify the IP address of the switch proceed to access remotely to the device “Command Line”

How to remotely access to 'ICX 7150-C12P' or 'access points' "Network devices":

https://community.ruckuswireless.com/t5/RUCKUS-Support-for-Lennar-Homes/How-to-remotely-access-to-ICX-7150-12P-or-access-points-quot/td-p/47388

If you can access the Command line should look like this:

ICX7150-C12 Router> OR

ICX7150-C12 Switch>

Please enter the below commands once you log in to CLI and share the output.

Note: Hit Enter to accept each command

enable

show version

show flash

Please share the output of the above commands or share the screenshots if stuck at any step or error (if any) and let me know if you have any queries in this regard.

Thank you again for your patience

Thanks for trying to help. However, this method is not working. I have found the ip address and can even log into the switch by typing the ip address into my google chrome web browsing bar. However, I cannot access it through the "terminal" on my macbook. I get the error message:

*******:~ ******$ ssh admin@192.168.1.72

Unable to negotiate with 192.168.1.72 port 22: no matching key exchange method found. Their offer: diffie-hellman-group14-sha1,diffie-hellman-group1-sha1

Hi @bbradley01

Thank you for the response and update.

Your both primary and secondary Switch partitions are running on SPS code, which is correct.

Please unplug and plug the ethernet cables of the Access Points from the Switch ports.

As your Switch is showing as pending/connecting it could be for multiple reasons, (Please refer to the below picture)

Please follow the below steps to get Switch in sync with Unleashed. We will delete the Switch from Unleased and Add it back.

Steps to synchronize the Switch (ICX-7150-C12P) to the unleashed Access Points:

Switch side:

Make sure the management approval is enabled.

https://docs.commscope.com/bundle/unleashed-200.9-onlinehelp/page/GUID-A887C55E-6973-4496-9413-302E8DE175AA.html

Access Points (unleashed):

On the Unleashed dashboard

1. Remove the existing Switch from the Unleashed (Please refer to the below picture):

2. Hit Add on that dashboard

3. Put the IP address of the ICX switch (ICX-7150-C12P) and Password (Same username and password you used for accessing the Switch from a Web browser).

4. Username and password for Switch authentication are the same as what you use to log in for Switch on a Web browser or CLI (Putty).

https://docs.commscope.com/bundle/unleashed-200.9-onlinehelp/page/GUID-30C6694A-6AEE-4DF8-9459-1AB189D415D2.html

To sync the data, it will take us a while, so after a couple of minutes, it should say connected.

Once the Switch gets synchronized, please check the dashboard again.

Please let me know if you have any queries in this regard.

Thank you again for your patience.
