Juniper SRX – Update the Operating System / Firmware

KB ID 0000989 Dtd 26/08/14


With two brand new SRX240 firewalls on the bench my first task was to get them updated to the latest operating system.


Before you start get the updated Juniper software.

Option 1 Update the SRX firewall via Command Line

1. Connect to the firewall via either Console cable, telnet, or SSH.

2. Log on and then go to CLI mode, and then configuration mode.

root@FW-02% cli root@FW-02> configure Entering configuration mode

[edit] root@FW-02#

2. The more observant of you will have noticed that it has already shown you the OS version above, but in case there is any doubt.

root@FW-02# show version ## Last changed: 2014-08-26 21:15:09 GMT version 12.1X44-D30.4;

[edit] root@FW-02# exit

3. I’ve always got 3CDeamon on my laptop so I’ll copy the update file over via FTP to the /var/tmp folder. (Note: We’re not at CLI or configure mode!)

root@FW-02% ftp Connected to 220 3Com 3CDaemon FTP Server Version 2.0 Name ( PeteLong 331 User name ok, need password Password:******** 230 User logged in Remote system type is UNIX.

4. Now perform the upgrade.

root@FW-02% cli root@FW-02> request system software add no-copy /var/tmp/junos-srxsme-12.1X47-D10.4-domestic.tgz NOTICE: Validating configuration against junos-srxsme-12.1X47-D10.4-domestic.tgz .

5. Then reboot the firewall.

root@FW-02> request system reboot Reboot the system ? [yes,no] (no) yes

Shutdown NOW! [pid 2749]


*** FINAL System shutdown message from root@FW-02 ***

System going down IMMEDIATELY

6. Post reboot, check the version again.

Option 2 Update the SRX firewall via J-Web

1. To check the current version > Connect to the web console > Dashboard > Software Version.

update srx via j web

2. Maintain > Software > Upload Package > Choose File > Browse to the file you downloaded earlier > Upload and Install Package.

Note: Here I have selected ‘Reboot Firewall’, in production you may NOT want to do that until later.

3. It can take a little while, (and look like nothing is happening), time for a coffee.

4. Post reboot, check the version again to make sure it has incremented.
