Junos OS Package Names

You upgrade the Juniper Networks Junos operating system (Junos OS) on a Juniper Networks EX Series Ethernet Switch by copying a software package to your switch or another system on your local network, then install the new software package on the switch.

A software package name is in the following format:

package-name-m.nZx.y-domestic-signed.tgz

• package-name is the name of the package—for example, jinstall-ex-4200.
• m.n is the software release, with m representing the major release number and n representing the minor release number—for example, 9.5.
• Z indicates the type of software release, where R indicates released software and B indicates beta-level software.
• x.y represents the version of the major software release (x) and an internal tracking number (y)—for example, 1.6.
• domestic-signed is appended to all EX Series package names. For most Junos packages, domestic is used for the United States and Canada and export for worldwide distribution. However, for EX Series software, domestic is used for worldwide distribution as well.

A sample EX Series software package name is:

jinstall-ex-4200-9.5R1.6-domestic-signed.tgz
