Services Routers 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-management command 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-management command brings the offline PIMs
online automatically.
To reenable J-series power management, remove the set chassis
disable-power-management command from the configuration. For detailed information
about the set chassis fpc offline and set chassis disable-power-management commands,
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.
