Upgrading Memory of Cisco ASA Firewall (5505,5510 etc)

Written By Harris Andrea

After the introduction of Cisco ASA software version 8.3 a few years ago, the device’s memory requirements for low-end models have been doubled.

Many firewall administrators have been discouraged from this move from Cisco because they had to upgrade their firewalls RAM memory in order to upgrade to the newest versions.

Upgrading the memory not only costs money but it imposes an operational hassle as well (network downtime, need to open-up the chassis etc).

I get many questions from my readers about memory upgrade guides, so the links below might be helpful for some of you.

The following guide shows the hardware maintenance and upgrade procedure for ASA 5510, 5520, 5540 etc:
