Fan Part Numbers for Cisco 2801, 2821 and 2851 fans

Unanswered Question
Mar 5th, 2008

I have P/Ns for Cisco 2811 router fans as follows:

ACS-2811-FAN-1/2= and ACS-2811-FAN-3=

But I do not have part numbers for fans used in 2801, 2821 and 2851 routers.

Does anyone have these prt numbers?

It doesn't make sense to change the whole router for just a fan failure.

I have this problem too.

I think Fan modules are not replaceble. Full chassis need to be ordered if FANs are failing.

Its not something most of us in here would do . It will certainly void any kind of warranty or maintenance contract on the device.

ACS-2821-51-FANS= should be orderable from Cisco. Why should we replace the whole chassis as the previous reply suggests

for the 2821 and 2851 routers the fan is the same : ACS-2821-51-FANS=

for 2801 the whole chassis needs to be replaced
