Engine. To upgrade software on an EX8200 switch running two Routing Engines, see
Installing Software on an EX8200 Switch with Redundant Routing Engines (CLI Procedure)
or Upgrading Software Using Nonstop Software Upgrade (CLI Procedure).
To install software upgrades on a switch with a single Routing Engine:
1. Download the software package as described in Downloading Software Packages from
Juniper Networks.
2. (Optional) Back up the current software configuration to a second storage option.
See the Junos OS Installation and Upgrade Guide at
http://www.juniper.net/techpubs/software/junos/index.html for instructions.
3. (Optional) Copy the software package to the switch. We recommend that you use
FTP to copy the file to the /var/tmp directory.
This step is optional because Junos OS can also be upgraded when the software
image is stored at a remote location.
4. Install the new package on the switch:
user@switch> request system software add package
Replace package with one of the following paths:
•
For a software package in a local directory on the switch—/var/tmp/package.tgz.
•
For a software package on a remote server:
•
ftp://hostname/pathname/package.tgz
•
http://hostname/pathname/package.tgz
where package.tgz is, for example, jinstall-ex-4200-10.3R1.8-domestic-signed.tgz.
Include the optional member option to install the software package on only one
member of an EX4200 Virtual Chassis:
user@switch> request system software add source member member-id reboot
Other members of the Virtual Chassis are not affected. To install the software on all
members of the Virtual Chassis, do not include the member option.
NOTE: To abort the installation, do not reboot your device; instead, finish
the installation and then issue the request system software delete
package.tgz command, where package.tgz is, for example,
jinstall-ex-8200-10.2R1.8-domestic-signed.tgz. This is your last chance to
stop the installation.
5. Reboot to start the new software:
user@switch> request system reboot
6. After the reboot has completed, log in and verify that the new version of the software
is properly installed:
user@switch> show version
