Wanna upgrade to that new IOS version to actually make your 2500 series Cisco router useful for something again but can't because you don't have enough RAM? I'll show you how to upgrade the RAM and where give you some advice on where to find some to upgrade to!
Step 1: Find Your Replacement RAM
First off, you're going to need to find the RAM you'll be upgrading TO, keeping in mind that the Cisco 2500 Series has only one slot for RAM and does not support sticks bigger than 16MB.
Your two main options here are:
A) Purchase some probably overpriced Cisco RAM.
B) Find a really old computer than still uses the 72-pin SIMMs and rip a (non-EDO) stick of RAM out of it.
I chose the latter as I still have several computers old enough to be using this RAM strewn about and settled on this lovely 16MB stick of RAM. The thing to note here is that it is:
- 16MB or less
- Has 72 pins (split equally into halves)
- Is not EDO. I don't know how to tell this from looking at it, I just already knew it wasn't ;P
