Upgrading the fans in a Cisco 2821 Router
Posted on 2012-04-04
I run around 4 Cisco 2821 routers with PVDM cards in handling all my voice data. I've noticed on two of the units the fans have died.
I was going to buy a fan replacement kit from Cisco at a cost of around £40.00 but when I took one apart I noticed that they ares tandard 80mm 12V fan units.
I'm considering now upgrading these from the standard fans that Cisco ship, to a couple of standard 80mm fans with a better quality rating.
Is there any issue around this? My warranty's are long void.
