Hi,

Does anyone know what is the maximum RAM that can be installed in cisco ASA 5540?

Thank you,

The 4GB DRAM is only for ASA 5580 model. It is not available for the lower ASA series.

So to answer your questions:

1. Yes, 2 GB is the maximum for ASA5540

2. ASA5540-MEM-2GB= comes with 2 DIMMS (1GB each).

2GB DRAM is currently the maximum memory on ASA5540.

Here is the release notes for your reference:

Hope that helps.

Thank you Halijen.

Looking at the release notes it does say

"On both the ASA 5580-20 and the ASA 5580-40 adaptive security appliances only 4 GB of memory is available for features. The rest are reserved or used by the OS. The show memory command will only display values relative to 4 GB."

1. Does this still mean that 2GB is the maximum memory we can install?

2. Does 2GB (ASA5540-MEM-2GB=) come as a sing module or 4x512 MB modules?

Rgds,
