UC520W Factory Restore Problem

Answered Question
Aug 11th, 2010

I need to return our UC520W back to factory condition.

By mistake, I did the copy flash:xxxxxx.cfg startup-config then reload before doing the CUE factory restore and lost the configuration for the default settings CUE. I don't know the factory settings to input.

What commands are required to configure the CUE so it can be accessed for factory restore? I'm having a problem setting the IP address, loopback, gateway, etc. so I can perform a factory restore.

I've seen posts with the commands to do the factory restore from the CUE but I can't get in there to do it.

I want to get the UC520W to a state where I can use the CCA.

Thank you.

I have this problem too.

It sounds like the default config file is not being loaded on startup.

Can you connect to the UC520 with a console cable.  Then look at the output of "show version". At the bottom, look to see the value of the configuration register.   This should be 0x2102,  if it is set to 0x2142, the system will not load your config file at startup.

Thank you,

Darren

UC520# service-module integrated-Service-Engine 0/0 session

This will take your into CUE system where you can issue the following commands:

UC500-CUE> offline

!!!WARNING!!!: If you are going offline to do a backup, it is recommended that you save the current running configuration using the 'write' command, prior to going to the offline state.

Putting the system offline will terminate all end user sessions.

Are you sure you want to go offline[n]? : y

UC500-CUE(offline)> restore factory default

!!!WARNING!!!: This operation will cause all configuration and data

on the system to be erased. This operation is not reversible.

Do you wish to continue[n]? : y

Restoring the system. Please wait .....done

System will be restored to factory default when it reloads.

Thank you for your response.

What commands do I need to set the IP address, gateway, loopback interface, etc. I get an error when I execute the following:

service-module integrated-Service-Engine 0/0 session

Thank you.

Steven DiStefano Thu, 08/12/2010 - 05:58

Not sure I am following?  What error did you get?  The Default Configuration file for the UC500 has all the interfaces at the correct setting 10.1.10.2 for the loopback.

Are you not able to get to it because you once adjusted CUE?  Can you adjust the UC500 side to match?

Yes, the CUE was once setup. I atempted to do a factory restore.

enable

show flash

copy flash:xxxxxxxxxxxxxx.cfg startup-config

reload

I get "Would you like to enter the initial configuration dialog? [yes/no]: Installed image archive"

I'm not sure what to do when I get the above question.

After I attempted the following:

service-module integrated-Service-Engine 0/0 session

I get "IP address needs to be configured on interface Integrated-Service-Engine0/0"

What are the commands to configure this interface so I can do a factory restore?

Thank you.

Steven DiStefano Thu, 08/12/2010 - 06:52

Ahhh so it looks like your in initial configuration mode, which to me sounds like the UC500 factory restart did not work.

We place all the default.cfg files in the UC500 bundle zip for all the possible SKUs.  You have to pick the one that matches your SKU.

Type 'no' at the Initial config prompt, and come to the IOS prompt.

Then at the IOS router enable yourself,  prompt (#) , and try again as follows:

#dir flash:

# copy startup-config

#reload

That should place the correct default interface configuration on the router, which I shared above in this thread.

srcasella Thu, 08/12/2010 - 07:01

Thank you. I think we are almost there.

I was able to complete the factory restore and got the following:

se-10-1-10-1#

I changed the IP address on my PC to 192.168.10.254 and plugged my cable into a PoE switch port on the UC520W.

I went into CCA was unable to connect to the UC520W at 192.168.10.1

Do I need to configure all of the interfaces in the command listing above even after I did the factory restore?

My goal is to be able to run CCA 2.2 (4) on the factory restored UC520W.

Thank you.

Steven DiStefano Thu, 08/12/2010 - 07:11

OK exit out of that CUE prompt (type exit) as you no longer need to be in there.

Unless you want to execute those manual commands I sent you earlier (to factory reset CUE)

Or you can do it with CCA....

Change your PC to obtain a dynamic IP address and plug in into any of the UC500 switch ports.

Get an Ip address (192.168.10.x) and launch CCA

You should be OK from there I think.

srcasella Thu, 08/12/2010 - 07:21

I'm still unable to connect to the UC520W using CCA after plugging an Ethernet cable into one of the switch ports. I can't ping 192.168.10.1, SSH, Telnet, etc.

I'm not getting an IP address assigned by the UC520W.

All appears to have gone well with the factory restore. However, I can't connect to the UC520W. The lights are flashing on the switch port I am using.

Is there any additional configuration needed for the interfaces after the factory restore, i.e no shutdown, IP addresses, etc. before using CCA?

Thank you.

Steven DiStefano Thu, 08/12/2010 - 07:27

Make sure you dont have your PC Wireless NIC turned on maybe?

Use Ethereal (Wireshark) on the interface and see if you see any activity....

The default config has the Data VLAN 1 ready with DHCP scope to serve the DHCP Discover from your PC.

If you cant ping it, you may have to console in to see if it dropped to ROMMON mode,  I hope that didnt happen, since that would indicate your UC500 is not happy about something.....

srcasella Thu, 08/12/2010 - 07:38

Vlan1 show unassigned YES unset up up.

It looks like there are no IP addresses assigned or DHCP pool after the factory restore.

How do I configure Vlan1 and DHCP so I can use CCA?

Thank you.

Steven DiStefano Thu, 08/12/2010 - 07:42

The factory reste should have done it all.  Since your wireless, you also have Bridged (BVI) interfaces.

Are you sure you used the Wireless version of the default configuration file.

Share with me the SKU and the default config file name you used....

You will have to open a case if these things dont help.....

srcasella Thu, 08/12/2010 - 07:50

The configuration file I'm using is:

UC520W-8U-4FX0-K9-factory-7.0.3.cfg

I obtained it using:

show flash

I have wireless disabled on my laptop and am using a wired connection to the UC520W.

If I had the factory default commands for the interfaces, I could enter them and try connecting to the UC520W via Ethernet. It doesn't appear factory restore is configuring the interfaces for the default values.

Would you happen to have the default interface commands?

Thank you for helping me with this problem.

Steven DiStefano Thu, 08/12/2010 - 07:56

When coming out of ROMMON or Router Initialization, interfaces are sometimes left SHUT.

You can try to console in to check this and 'no shut' them.

I would prefer at this point you open a case with TAC.

The interface commands are in that configuration file.  The whole configuration is.

You can cut and paste the interface sections into your system, but as I underdstand, you cant access your system.  So its probably not in a happy state and needs to be diagnosed I think.

srcasella Thu, 08/12/2010 - 08:10

When I configured interface Vlan1 with an IP address, I was able to ping it when using a static IP address on my PC. However, I couldn't connect via CCA.

It appears the UC520W is fine. I can enters commands without a problem.

If I knew which commands to enter to configure the interface, it should work.

I'd appreciate it if you would help with this last step. All of the other commands worked fine. It apears factory restore leaves out a couple of steps on my UC520W.

Thank you.
