It depends on your environment.&nbsp; If you are building your infrastructure during construction, switches, routers, blades, optics tent to get dirty rather quickly.&nbsp; So, you need to clean them often.</P><P>If not, doing it once a year maybe enough.&nbsp; Overall, there is no set rules.</P><P></P><P>HTH</P></BODY></HTML> Wed, 05 Jun 2013 21:19:59 GMT https://community.cisco.com/t5/switching/catalyst-6500-4500-pmi-instructions/m-p/2216729#M256523 Reza Sharifi 2013-06-05T21:19:59Z
