Upgrading the JUNOS Software on an Operational T1600 Router and TX Matrix Plus Router
Upgrading and integrating an operational T1600 router requires the following:
- JUNOS Release 10.1 or later
- The TX Matrix Plus router and T1600 router must each contain two host subsystems. All host subsystems must be running the same JUNOS Software release. This is a requirement for graceful switchover. Graceful switchover must be enabled to integrate an operational T1600 router. For information about graceful switchover, see the JUNOS High Availability Configuration Guide.
To upgrade the software, you use CLI commands to copy a set of software images over the network to memory storage on the Routing Engine. The JUNOS Software set consists of several images provided in individual packages or as a bundle. You normally upgrade all packages simultaneously.
For information about installing and upgrading JUNOS Software, see the Routing Matrix with a TX Matrix Plus Router Feature Guide and JUNOS Software Installation and Upgrade Guide.
To upgrade the software:
- Upgrade the JUNOS Software running on the T1600 router.
- Upgrade the JUNOS Software on the TX Matrix Plus
router to the same release running on the T1600 router.
For information about installing and upgrading JUNOS Software, see the Routing Matrix with a TX Matrix Plus Router Feature Guide and JUNOS Software Installation and Upgrade Guide.
- After you are satisfied that the new packages are
successfully installed and running, issue the request system snapshot command to back up the new software.
For more information, see the JUNOS System Basics Configuration Guide.
