C9115AXE error at 0day setup

[gregory1]

Hello,

My C9115 with EWC was working fine and after a power outage no more SSID broadcasted and remote web administration no more accessible. The IP address was even not possible to ping.

After a full reset with the mode button, I try to do again the 0 day setup with CLI commands via the console. I can set the IP address on the GigabitEthernet0 but as soon as I send the "write mem" command I got an error message: "Failed to save vrrp-ip.txt". The web administration address is still not accessible.

Is AP dead or possible to recover it with commands?

Thanks for your help

Can you re-image the EWC AP and try again.

Thanks for your answer. I don't even have an IP address to connect to a TFTP server. How can I do? It seems there's a USB port, can I use a USB drive for that?

   - Is there anything else in the logs (show logging)  after you issue write mem ?

Yes.

Here it is.

Can you make sure that there are no any other WLC of any kind is reachable in the same broadcast domain(VLAN). Just try to isolate your WLC on its own VLAN with gateway reachability  and try again.

[gregory1]

Hi,

There's no other WLC on the same LAN. This AP is connected on it's own switch with other equipment but no AP.

BTW, I could get rid of the previous error (Failed to save vrrp-ip.txt) by issuing the command "write erase" seen in another thread here.

It seem that nvram has been flushed but I can still see that some settings are persistent in the AP config (like datarates etc...) even right after 0day setup is completed. Finally the interface is still not accessible from my network.

Is there a way to restart from zero? I would like to totally erase all settings of the embedded WLC as well as the AP. Actually I was trying to configure the loopback interface and DHCP pool before the power outage, maybe it has rebooted with incorrect settings, but no idea which one it is...

Thanks

To factory reset;

EWC#wireless ewc-ap factory-reset

[gregory1 · Accepted solution]

Hi Arshad,

Actually I did the factory reset but didn't change the fact that I still couldn't connect to the Web interface after setting an IP address (of my local NW) on the GigabitEthernet0 interface. Actually I forgot that after a full reset the AP is in DHCP mode. So I plugged it on my company lan to get an IP and I was able to access the web interface. Now I put a fixed IP address on the interface as well as for the AP (otherwise impossible to connect to Interface) in order to use it on my local network. 

Now everything is working fine. Thanks for you help
