Introduction

This document describes how to reset Cisco IR829 devices to its default configuration.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

- Console access to the device

- Paper clip to press the reset button

Components Used

The information in this document is based on Cisco IR829 Router.

The information presented in this document was created from devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If you are working in a live network, ensure that you understand the potential impact of any command before using it.

Background Information

The rommon in IR800 series routers is totally different from the rommon found in most other Cisco devices.

You cannot do a password recovery on IR800 series routers in the usual sense because IR800 series routers do not support the config-register setting to allow you to bypass the startup-config. You can only "recover” your routerwhen you wipe out its startup-config.  Ensure you save a copy of your working running-config to a file on flash, just in case you can need it again later on. It has a Reset button to reset the device to its factory-default settings.

Note: There is no way to recover the startup configuration once the device is Reset.

Procedure

Method 1. For Cisco IOS® Version 15.5(3)M5 or Earlier

If the version of the Cisco IOS® is 15.5(3)M5 or earlier, then the device must be booted to password prompt before you reset the device.

Once you see the password prompt, long press the reset button for 30 seconds until this message appears:

*Jan 28 05:21:24.143: %FCPLMGR-5-CFG_BUTTON_LONG_PRESSED: Config reset button was held for more than 10 seconds. NVRAM filesystem erased.

*Jan 28 05:21:24.145: %SYS-7-NV_BLOCK_INIT: Initialized the geometry of nvram

*Jan 28 05:21:24.145: %SYS-5-RELOAD: Reload requested by IR800 Fcplmgr OS events dispatcher. Reload Reason: Configuration Reset button (long) pressed.

%FCPLMGR-5-CFG_BUTTON_LONG_PRESSED: Config reset button was held for more than 10 seconds. NVRAM filesystem erased.

This erases the content of the NVRAM and the device reboots itself in rommon-2 prompt.

Boot the IOx from the rommon-2 prompt. The IOx image starts the boot sequence and once completed, the device must come up with factory default settings.
