Can I use same firmware for different SRX models?

I need to install firmware 11.4R5.5 in a SRX240. In my documentation I've found this file: junos-srxsme-11.4R5.5-domestic.tgz but I don't know if this firmware belongs to an unique SRX model or if it can be used for every SRX model

It is not recommended although you may have more than one answer to this question

 

 

With JUNOS software you don't have these trade-offs. For each new version, the Juniper engineers compile the full set of release binaries so that each version is available to run all the Juniper platforms run by JUNOS software

Re: Can I use same firmware for different SRX models?

Hi,

 

Junos 11.4 is End of Support and not a very stable release. I would suggest using the latest recommended firmware :-

https://kb.juniper.net/InfoCenter/index?page=content&id=KB21476

 

The file "junos-srxsme-11.4R5.5-domestic.tgz" can be used on any current Gen Branch SRX device, Ex - SRX100, 110, 220, 240, 550, 650.

 

The newer models use the 15.1 series.

 

For SRX 1k/3k, the images will be different and start like junos-srx1k3k....

For SRX 5k, the images will be junos-srx5k.....

 

Hope this answers your question.

 

Regards,

Sahil Sharma

SRX firmware for the branch series is all the same file.

 

the files change when you go up to the 4 digit models and the vSRX.

'junos-srxsme" packages can be used on any SRX branch series supporting 11.4.(SRX100,SRX220,SRX240,SRX650 etc)

 

"junos-srx1k3k" packages can be used on SRX1400,SRX3400 and SRX3600

 

Same way "junos-srx5000" can be used on SRX5400,SRX5600 and SRX5800.

 

 

 

 

Thanks,
