Upgrading Memory of Cisco ASA Firewall
After the introduction of Cisco ASA software version 8.3 last year, 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 table shows the new memory requirements for all Cisco ASA 5500 models for software version 8.3 and later:
The following video from Cisco shows you how to upgrade the memory chip on a Cisco ASA 5510 Firewall.
