PSA: Owners of Nexus 7004/7010's, it's time to clean your filters.

If you have a Nexus 7004/7010 there is a good chance it has an air filter installed. After approx 5-8 years of operation these filters will become clogged with dust and start to overheat the chassis. I'd highly recommend performing the cleaning guide found [1]

To figure out if you do have a filter run the command

7k# show env | grep ig filter Fan Air Filter : Present

HTH!
