Catalyst 6500/4500 PMI Instructions

Are there any best practices for preventative maintenance on Catalyst Chassis switches.  Looking to build a PMI schedule for a customer.  Or is there evidence not to perform it at all.  Things like re-seating line cards, cleaning fan exhausts, etc.

What is PMI?

Usually you don't need to reseat you line cards unless there is an issue and reseating can fix them.

As for cleaning fan, exhaust, etc.... It depends on your environment.  If you are building your infrastructure during construction, switches, routers, blades, optics tent to get dirty rather quickly.  So, you need to clean them often.

If not, doing it once a year maybe enough.  Overall, there is no set rules.
