H960 question, and part available

[Paul Anderson]

Hi Jay,

I believe they were shipped from the factory with the fans blowing downward,
thus the channels to hold the filter on top of the cab.The thought might
have been not to bring contaminants up from the floor, and there was enough
airflow to dissipate the heat. Not all computer rooms were really clean.

If the customer had a raised computer floor, the filters were taken off and
the fans reversed, to work with the clean air coming in from the bottom.
