Booting The Ge-2 Line Module - Juniper SYSTEM BASICS - CONFIGURATION GUIDE V 11.1.X Configuration Manual

JUNOSe 11.1.x System Basics Configuration Guide
In addition, you can configure the system to load a different software release file on
its next reboot. Use the boot system command to do this. If you do not configure
your system with a backup release, it reverts to the release and configuration it had
before the crash.
You can use the boot backup command to specify a software release and
configuration for the system to use in case the system resets too many times in a
given period.
The boot subsystem command enables you to override the system release setting
for a given subsystem for example, OC3.

Booting the GE-2 Line Module

The GE-2 line module can now detect whether it supports the software release installed
on the primary SRP module in an E Series router. When the GE-2 line module is
booting and it detects that it supports the software release on the SRP module, the
line module boots successfully with that software release. However, if the GE-2 line
module detects that it does not support the software release on the SRP module, the
module does not boot successfully and the following messages appear in the system
log:
boot backup
boot config

You can require the system to reboot from an existing configuration file, from
an existing local script file, or with the factory default configuration.
Example
host1(config)#boot backup rel_1_1_0.rel newfile.cnf
