ASA 5520 flash upgrade from 256Mb to 512Mb

[Peyman Sadeghi]

Hi All

I need to upgrade the flash memory of the ASA 5520 from 256Mb to 512Mb. As far as I reallized the built-in flash memory called system compact flash and there is also an empty slot which it is possible to install a user flash.

What is the difference between user and system compact flash? and for upgrade can I just insert the user compact flash or do I need to upgrade the system compact flash?

Where can I find the part number for each type?

Peyman

What are you trying to upgrade your ASA to? If you are trying to upgrade your ASA to version 8.3 or above, here is the memory requirement:

Part number is also available on the same URL above.

What is the difference between user and system compact flash?

Not much, the system flash is installed on the ASA by default and can't be removed, "user's" flash has to be added and can be removed, they both store files from/for the ASA .

To upgrade the unit, you just have to insert the card, try to do this while the ASA is down.

Check the "Background information" section.

This is the part number: ASA5500-CF- 256MB
