After years of use the power supply fan on my Cisco 3745 router went bad so its time to change it. A great feature on this router is that it has redundant power supply’s so you can run on just one PSU. I have been running it for 6 weeks on one power supply and everything works fine but I wanted to get this done fast because some of the 3745 parts are hard to find.

I took the power supply apart and took the fan out.  Just unscrew the tiny screws holding the metal plates on. Now unscrew the 4 screws on the circuit board.

The fan is a model 2410ml-04w-b69 12 volt DC 0.040 A made by Minebea Co. I did a search for the model 2410ml-04w-b69 and found the cheapest on ebay.

When I got the new Cisco 3745 power supply fan 2410ml-04w-b69 the connector was the wrong one so I took off the old one and put it on the new fan.

After putting the old connector on the new fan I plugged it in, screwed in the fan and the circuit board. Next I put the metal plate back on and plastic shield then screwed it in. Now plugged it into the 3745, plugged power cord in and flip switch. Everything worked fine and was EZ to do.
