A couple of years ago I got an old Cisco PIX506e to use as firewall for my home network.
This is a really nice equipment and even if they are a bit complicated to configure, they are very reliable.
Well, about a month ago my PIX stopped working ... a little troubleshooting indicated that the power supply was dead.
I looked around but I was unable to find any supplier in Argentina (where I currently live), and while i could get one off EBay for about U$D 20 the shipment to South America would increase the cost considerably (not to mention the Custom's Fees once in here)
So, I started looking for alternatives.
I check with a local Radio/TV repair store and they could look into fixing it, but I would have to pay a "diagnostic fee" of $40 (about U$D 10) in order for them to tell me IF they could repair it (and for how much).
I might still take it to repair, but I wanted a cheaper solution.
This instructable will show you how I adapted an old "AT type" Power Supply from a discarded computer to power a Cisco Pix 506e.
I'm describing what I done (except noted) and what it worked for me, to the best of my abilities and as much as I can remember.
If you want to follow this instructions do it at your own risk.
