1643257: MCC A/C outage: Fan reconfig made big difference 

Adam and David reconfigured the fans that we had so that the large/industrial fan was blowing INTO the equipment room from the control room (and any other fans were setup to blow OUT from the equipment room into the hallway). This made a BIG difference in the systems we were monitoring (opsll, devll, etc.) and we should definitely do this again the next time the A/C fails.
We saw an almost immediate drop of about 5 degrees C in system temperature, and it's continuing to drop.
