Software

Overview

Caution: Check the Release Notes for extra information about installing and
upgrading the software.
The E-series software resides on an NVS card located in the SRP module.
We ship every SRP module with an NVS card that contains a software
release. We ship new software releases on a CD. This appendix provides
information on how to install a new software release on an E-series router.

Upgrading Systems That Are Operating with Two SRP Modules
If the router contains only one SRP module, you should divert traffic to
another router before you install a new software release, because the
router will be unavailable during the installation process. Depending on
whether a firewall separates the E-series router from the network host,
you can then complete the appropriate software installation (see
Software When a Firewall Exists
Does Not Exist ) . However, if the router contains two SRP modules, you
can upgrade the software while the system is operating (see
Systems That Are Operating with Two SRP Modules
When installing new JUNOSe software, you must mount the software
CD on a network host and transfer the release files to at least one E-series
