The root file system is backed up to /altroot, and /config is backed up to /altconfig.

The root and /config file systems are on the router’s CompactFlash card, and the

/altroot and /altconfig file systems are on the router’s hard disk or solid-state drive

(SSD).

NOTE: After you issue the request system snapshot command, you cannot

return to the previous version of the software, because the running copy

and the backup copy of the software are identical.

NOTE: SRX5000-line devices, the root file system is backed up to /altroot,

and /config is backed up to /altconfig. The root and /config file systems

are on the router’s CompactFlash card, and the /altroot and /altconfig file

systems are on the router’s hard disk or solid-state drive (SSD).

NOTE: This step is optional for SRX300, SRX320, SRX340, SRX345, and

SRX550M; for these devices, ensure that a USB flash drive is plugged into

the USB port of the device.

3. If you are copying multiple software packages to the router, copy them to the /var/tmp

directory on the hard disk or solid-state drive (SSD):

user@host> file copy ftp://username :prompt@ftp.hostname

.net/filename/var/tmp/filename

4. Add the new software package:

•

To add an individual software package:

user@host> request system software add/var/tmp/ installation-package validate

installation-package is the full URL to the file.

NOTE: For SRX5800, SRX5600, and SRX5400 devices, do not include

the re0 | re1 option when you install a package using the request system

software add command, if the Routing Engine on which the package is

located and the Routing Engine on which you want to install the package

is the same. In such cases, the package gets deleted after a successful

upgrade.

If you are upgrading more than one package at the same time, add jbase first. If you

are using this procedure to upgrade all packages at once, add them in the following

order:

user@host> request system software add /var/tmp/jbase-release-signed.tgz

user@host> request system software add /var/tmp/jkernel-release-signed.tgz
