Complete procedures for installing the system software are available in JunosE System
Basics Configuration Guide, Chapter 3, Installing JunosE Software.
New software releases are available for download from the Juniper Networks website
at http://www.juniper.net/customers/support. You can use the downloaded image
bundle to create your own software CDs.
Before upgrading to a new version of software, save your router's running configuration
to a .cnf file or .scr file. If you subsequently need to downgrade for any reason, you can
restore the earlier software version.
Informational Note:
When you upgrade the software on a router that has a large
number of interfaces configured, the router might appear to be unresponsive for
several minutes. This condition is normal; allow the process to continue
uninterrupted.
When you upgrade from a lower-numbered release to Release 5.3.0 or a
higher-numbered release, the higher release might not load if you issue the boot
system command from Boot mode while the lower-numbered software is running on
the router or if you insert a flash card running a higher-numbered release into a system
running a lower numbered release. However, if you issue the boot system command
from Global Configuration mode, the new software loads properly.
Release 5.1.1 or lower-numbered releases support application images only up to 172 MB.
Your software upgrades or application images may be available remotely through
Telnet or FTP, or may be delivered on a new NVS card. If you upgrade the JunosE
Software using a new NVS card, we recommend you perform the upgrade in two
stages: first to an intermediate release and then to the higher-numbered release you
want to run. This restriction is not applicable if you upgrade your software remotely
through Telnet or FTP.
To install larger application images for Release 6.0.0 and higher-numbered releases,
you must first install Release 5.1.2 (or a higher-numbered 5.x.x release). This enables
the system to support application images greater than 172 MB. For example, if you are
upgrading the software using a new NVS card, you cannot go from Release 5.1.1 to
Release 7.2.0 without first upgrading to Release 5.1.2.
