Juniper Networks Guide to Juniper Reset Configuration and Rescue Configuration Management

JUNOS Software with Enhanced Services Hardware Guide

■Remove one or more PIMs from the chassis. This option requires that you power off the router. For more information about removing PIMs, see “Removing a PIM” on page 120

■Bring the PIM online without powering off the router. To do so, use the set chassis fpc offline command to set another PIM slot in the chassis to the offline state. For example:

user@host# set chassis fpc 2 offline

If the power and heat tokens no longer exceed the maximum, the PIMs that were placed offline by J-series power management are brought online automatically.

■Use the set chassis disable-power-managementcommand to disable J-series power management:

user@host# set chassis disable-power-management

CAUTION: Use extreme caution when disabling J-series power management. To prevent equipment damage, do not install a combination of PIMs that exceeds the power or heat capacity of your router when J-series power management is disabled.

The set chassis disable-power-managementcommand brings the offline PIMs online automatically.

To reenable J-series power management, remove the set chassis disable-power-managementcommand from the configuration. For detailed information about the set chassis fpc offline and set chassis disable-power-managementcommands, see the JUNOS System Basics Configuration Guide.

Resetting the Configuration File When the Router Is Inaccessible

You can use the router's RESET CONFIG button to restore the router's configuration file when the current one is faulty or fails. You can also change the default behavior of the RESET CONFIG button.

Using the RESET CONFIG Button

If a configuration fails or denies management access to the router, you can use the RESET CONFIG button to restore the router to the factory default configuration or a rescue configuration. For example, if someone inadvertently commits a configuration that denies management access to a router, you can delete the invalid configuration and replace it with a rescue configuration by pressing the RESET CONFIG button. The button is recessed to prevent it from being pressed accidentally.
