What are the "cfm" values when performing a show environment command

Team

I was early performing a "sho env" on a Cat 6506 and i see certain values entitled "CFM".

Here is an example:

chassis per slot cooling capacity: 94 cfm
ambient temperature: < 55C
  module 1 cooling requirement: 84 cfm
  module 2 cooling requirement: 84 cfm
  module 3 cooling requirement: 70 cfm
  module 4 cooling requirement: 70 cfm
  module 5 cooling requirement: 35 cfm
  module 6 cooling requirement: 70 cfm

what does the "cfm" stand for / represent in this context?..

Thank You.

Hi Kevin,

CFM is Cubic Feet Minute and is the airfflow required to maintain the cooling for the installed module.

Take a read of the Wikipedia page Actual cubic feet per minute if you want more details. Personally I was happy to know the meaning of the acronym :)
