Diagnosing mechanical problem on 2501

[ericscher]

I just bought a could of used 2501's knowing one was bad but not knowing HOW it was bad.

Upon turning on the power, with a console connection open I get NOTHING.

The power supply works well enough to run the fan, but I don't know if it works well enough to run the main board. For that matter, the board may be bad.

I would LIKE to repair this router and use it, but obviously some repairs may not be cost effective when I can get used 2501's for only a few hundred dollars.

Here's the question:

Are there any tests I can do, perhaps with a voltage meter, that would help me narrow down the problem so that I can determine if I am better off repairing it or just consigning it to the parts bin?

If you are absolutaly certain the router is faulty, your symptoms warrant trying different baud rates on the console ?

Do you get an OK light on the router ?

Try connecting to a switch and see if you get CDP info ?

If you look at the main board you can see not too much is replaceable. If you have a working 2500, move the RAM, Flash and power supply into the faulty router and see if it works ?

You may be able to isolate the faulty component and if you choose not to repair it, you can use the rest as spares ?
