MD110 boards and dust

[Ghoulam]

Hi everybody

Does someone knows how to eliminate dust from system boards in general or MD system in particular.
Do we have to stop the system and vacuum it, or is there a way to clean it without stop it, or is it better to leave it with dust (some say dust is good for the system) is this true?

Thank you all guys.
