Note: SRX100, SRX210 and SRX240 come in base memory and high memory options.

Base memory versions have 512MB of memory and the high memory versions have 1GB of memory.

SRX100 is unique in that the high memory option is a licensed feature.

This means that SRX100-B (Base memory) units can be upgraded to SRX100-H (high memory) units with the purchase of a license key.

The other branch models cannot be upgraded to high memory units with a license key as the hardware is slightly different.

They are specifically purchased as base or high memory units.

SRX110, SRX220, SRX550 and SRX650 only come in high memory versions.

In addition to this SRX240B2 comes with 1 GB DRAM and 2 GB Flash, SRX240H2 comes with 2 GB DRAM and 2 GB Flash.
