Configuring Router for Image and Config Recovery Using Push Button

A push button feature is available on the Cisco 819 ISR. The reset button on the front panel of the router enables this feature.

Perform the following steps to use this feature:

Step 1 Unplug power.

Step 2 Press the reset button on the front panel of the router.

Step 3 Power up the sytem while holding down the reset button.

The system LED blinks four times indicating that the router has accepted the button push.

Using this button takes effect only during ROMMON initialization. During a warm reboot, pressing this button has no impact on performance. Table 5-4shows the high level functionality when the button is pushed during ROMMON initialization.
