Copy Image
First of all we copy the image over to the SRX via the use of scp. In this case I have used putty's pscp.
C:\Windows\System32>pscp "C:\Users\admin\Downloads\junos-srxsme-11.4R1.6-domestic.tgz" root@[SRX IP]:/mfs
Confirm Hash
Next we confirm that the file is complete and is not corrupted by clarifying the MD5 hash of the file. The MD5 files can be obtained from the same page as the image files from within Junipers download section.
root@srx100> start shell
root@srx100% md5 /mfs/junos-srxsme-11.4R1.6-domestic.tgz
MD5 (/mfs/junos-srxsme-11.4R1.6-domestic.tgz) = 1a98b252c4b74f4de0ff8a87bf95194f
Upgrade
The device is then upgraded by issuing the following command.
root@srx100> request system software add no-copy validate /mfs/junos-srxsme-11.4R1.6-domestic.tgz
