WARNING: Please install an SRX image supported for 2G

This issue is tracked via PR 987067.

Solution:

There are two possible solutions available to work around this issue:

Solution 1) Use release 12.1X44-D40, 12.1X45-D30, 12.1X46-D25, 12.1X47-D10 or later releases as an interim release.

To use this solution, follow these steps:

1. Install one of the above interim releases
2. Reboot
3. Install 12.3X48 release

Note: You may use regular means of installing the Junos software, e.g. the cli command request system software add or J-web or NSM/Space management platforms for this process.

Solution 2) Upgrade directly from an affected release to 12.3X48-D10 and above using a special script.

To use this solution perform the below steps:

1. Download install script
https://download.juniper.net/software/junos/specials/JTAC/script/package.tar.gz


2. Place install script on SRX


3. Open shell prompt and move to directory where install script was placed
root@srx210HE2>start shell
root@srx210HE2%cd /var/tmp


4. Optionally verify integrity of install script placed on SRX
root@srx210HE2%md5 package.tar.gz
MD5 (package.tar.gz) = 29d1bb47845647aae1cec6b69fc6fb44


5. Un-compress script
root@srx210HE2% tar zxf package.tar.gz    (A new folder will be created called package)


6. Change directory to new folder labeled package
root@srx210HE2% cd package


7. Install script
root@srx210HE2% sh ./manifest.loader
Verified manifest signed by PackageDevelopment_9_6_0


8. Install 12.3X48 using install script, using optional -no-copy, -no-validate, -reboot commands
   
     NOTE: This step cannot be done using normal CLI 'request system software upgrade' commands.
                If using -reboot option, for automatic device reboot after upgrade, skip Steps 9 & 10


root@srx210HE2%./package <–no-copy> <–no-validate> <–reboot> add <image location/name>
Example: root@srx210HE2%./package -no-copy add /var/tmp/junos-srxsme-12.3X48-D10-domestic.tgz


9. Exit Shell
root@srx210HE2%exit
root@srx210HE2>



10. Reboot system at your convenience
root@srx210HE2>request system reboot
Reboot the system ? [yes,no] (no) yes
Shutdown NOW!


11. Verify upgrade version post reboot
root@srx> show version
Hostname: srx
Model: srx210he2
