I will be making a post about this as well when I have done the upgrade. This is a very easy process as well, but you have to be careful to copy over your licence files as well.
I plan to upgrade the CompactFlash to 4GB as well so I have more working space when I am using the “packet sniffer” built into the ASA.
Intrigued by this, and due to needing the extra RAM for the 8.3 code, I decided to upgrade both my ASAs to 1GB as well! Denied due to NAT reverse path failure - Cisco ASA 5545. (6) it looked a bit like this: Nat Exempt Example on a Cisco ASA 5505 The use of Network. When I originally performed this upgrade, I found that on various forums many people had actually upgraded past the official supported amount of RAM, and upgraded their ASA 5505s to 1GB RAM. Denied due to NAT reverse path failure - Cisco ASA 5545. This is also the maximum officially supported amount of RAM.īuying official Cisco RAM is, as always, quite expensive, but since the ASA 5505 uses standard DDR RAM, it is actually possible to use third-party RAM in the ASA 5505.
Starting from ASA 8.3, the minimum required RAM needed to run 8.3 code and newer on a 5505 is 512MB. Pretty much straight away, I wanted to upgrade to the ASA 8.3 code, which required a RAM upgrade, so I upgraded it. I was pretty lucky, as I paid under £70 for each because the seller wasn’t too sure what they were! Looking on eBay now, they are selling for around £120! ? I have two Cisco ASA 5505s in my home lab which I acquired almost two years ago from eBay.
Identify an ASA interface where the rommon>interfaceInterrupt the bootup sequence Press Esc or Break at the appropriate time. Edit: 3rd June 2014 – If you are reading this post, you should check out my follow up post: Cisco ASA 9.2 on Cisco ASA 5505 with Unsupported Memory Configuration Fail. For this scenario, well be doing the latter and here are the steps for booting an ASA image file when in ROMMON mode: Steps ROMMON Command.
