Chapter 4
Completing a Standard or Change
Category Installation
This chapter describes how to perform a standard or change category installation of
the JUNOS Software.
For information about JUNOS Software media and packages, see “Introduction to
JUNOS Software” on page 3. For information on the installation process, see
“Installation Overview” on page 25
NOTE: When you upgrade from a previous installation of the JUNOS Software to
Release 8.4R1 or later on an MX Series router, the MAC addresses on the Dense Port
Concentrator (DPC) Ethernet ports change.
The change category installation process is used to move from one category of the
JUNOS Software to another. For example, you can move from standard JUNOS on
an M Series router to the export version of JUNOS Software. When performing a
software category change, you need to take special precautions during the installation.
These precautions delete the previous installation and prevent users from rolling
back the server to these older installations.
