When performing the factory reset procedure we are about to describe, it is important to keep in mind that the IP phone will lose all configuration files and phone applications. This means that it is necessary to have CallManager or CallManager Express setup so that the IP phone will be able to receive the new information (phone application and configuration) after the reset procedure is complete, otherwise it is most likely that the IP phone will not be usable until this information is loaded on to it.
This preparation also happens to be the procedure for upgrading a Cisco IP phone firmware.



Follow the steps below to successfully factory reset your Cisco 7942, 7962 IP phone:

  1. Unplug the power cable from the phone and then plug it back in. The phone begins its power up cycle.
  2. While the phone is powering up, and before the Speaker button flashes on and off, press and hold #. Continue to hold # until each line button flashes on and off in sequence in amber.
  3. Release # and press 123456789*0#.
You can press a key twice in a row, but if you press the keys out of sequence, the factory reset will not take place.
After you press these keys, the line buttons on the phone flash red and the phone goes through the factory reset process.
Do not power down the phone until it completes the factory reset process and the main screen appears.

Can get router to work


The Cisco Aironet 1200 access point provides secure wireless connection to your network. Cisco's wireless access design meet the needs of a small to medium size business.

This unit provides secure network access for laptops or Wi-Fi capable portable devices, which you upgrade at any time as your business grows.

A beneficial feature of the Cisco Aironet 1200 is its ability for the administrator to reset the access point remotely.

This resetting process works through your internet browser.
Log on to the System Configuration page by entering your Cisco Airnet 1200 IP address in your browsers web address text box.

Enter your user and password information from the pop up menu.
Click on the "Setup" button from the summary status page.


Select the "Cisco Services" setup option and click on "Manage System Configuration."
Click on "Reset All System Factory Defaults" to reset the router.

The Cisco Aironet 1200 will be restored to factory defaults.

Default password for a Cisco SG200-26? cisco, cisco do not work .. ??


I had the same issue after what I thought was a succesful reset. It turns out I hadn't reset the switch completely. There is a reset pin hole next to the power switch. Hold it in with a paper clip for at least 30 seconds. ( I was holding in the power button for 30 seconds.)Then you can use the cisco admin and cisco for password defaults. Hope this helps someone in the future since I spent WAY TOO MUCH TIME on it :)

My Cisco IP Phone 7945G keeps rebooting after I did a factory reset. Is there a way to fix this?


According to Cisco, when initiating a factory reset procedure certain information from the IP phone is erased while other information is reset to the factory default value, as shown in the list below:


Information Erased:
  • CTL File (Certificate Trust List)
  • LSC File (Locally Significant Certificate)
  • IP Phone Call History (Calls Received, Placed, Missed etc)
  • Phone application
Information Reset to Default:
  • User configuration settings (ring tone, screen brightness, sound levels etc)
  • Network configuration settings

t is highly advisable to follow the firmware upgrade procedure in a non-working environment to ensure other phones are not affected (in case of an accidental reboot), and to avoid the freshly factory reset ip phones obtaining the working environment's settings.


Please use the link below and follow the instruction http://www.firewall.cx/downloads/cisco-tools-a-applications/cisco-ip-phone-a-ata-firmware-downloads.html

I had a power shutdown and after my Cisco E1000 router suddenly stopped working. All the lights just completly froze (not blinking) just froze and i dont know what to do. Any help would be greatly app


Try resetting the router to factory defaults. With power on the router, hold the reset button in for 15 seconds, it'll be reset to factory defaults.


Try this at least 5 times before giving up!


Hope this helps!

How to reset to factory default?


Hi nbergma,

To Factory reset your router you need to locate the Reset Button at the back of the router. The Reset Button is the small hole at the back and you need a Pen or a Paperclip to press it. Press and hold the reset button for 10-15 seconds. Make sure that the router is on when you reset it.

Thanks for using Fixya.
