    It has come to my attention that the base memory versions od the SRX210 and SRX240 CANNOT be upgraded to a high memory version. Is this correct? Will this change in the future?


    Are any other specs or capabilities scaled back on these lower memory version?


    Thanks in advance!

    Unfortunately this is true. SRX210 and 240 are currently sold with low-mem (base w 512MB) and high-mem (1GB) versions. High-mem also offers POE version as well. The memory is not field replaceable. So if you intend to implement UTM or IDP, be sure that you have high-mem version as low-mem doesn't support those features.

    I was wondering if I can upgrade the memory in SRX 210 BE to 1GB and install UTM license? 


    If I can't upgrade, what are other solution to get UTM running? Replacing the device?

    Unfortunately, srx210 memory is not upgradable, just by design. If it was srx100, you could buy a license to increase memory from 512m to 1g (as it always has 1g inside even for a cheaper low-mem version), but for srx210 - you have to replace it to run UTM.


    Note that currently you can buy srx210he - high-memory and faster CPU, than it was in old (non-"e") srx210. It goes at the same price as old srx210h.

    You can try the new H2 devices with 2G memory ( 2GB ram and 2GB flash).

    For SRX210 & SRX240 (First Gen.) - you CAN upgrade the RAM to 2G. You will still have 1G FLASH, but your memory can double. If you want to install JunOS 12.1X47... you will need to change the checking in the JunOS. Check the Michael's RAM and JunOS tweaks to install newer ver of JunOS with 2GB RAM

    I hope it helps.

    I've an SRX-210B and I'm interested in memory up-grade. It's enough to change memory into appliance or else? Why Juniper says that it's impossible by design?


    Some one knows SRX210lm? What is it? I've one of them but I can't find it's description on Juniper site.


    Thank you in advance.
