Removal and replacement procedures  32 

3.

 

Replace the cooling fan bank wire harness (3). 

 

4.

 

Connect the power supplies to the cooling fan power assembly. 

5.

 

Return the fan bank to the AUTO mode of operation. 

 

Cooling fan controller 

The cooling fan controller supplies power to the fans. The ECS sends control signals to increase or decrease 

the fan speed to regulate cold-aisle pressure and hot-aisle temperature. 
The cooling fan controller is located in the ceiling in front of the fan banks.   

  

 

CAUTION: 

 Removing the cooling fan controller makes all fans within the affected zone 

inoperable. Take this into consideration when deciding whether to continue operating IT within 
the affected zone. HP recommends powering down all IT in the zone. 

  

You need a screwdriver to remove and replace the cooling fan controller. 

 

Removing the cooling fan controller 

1.

 

Electrically isolate the affected zone by opening the associated zone fan breaker. 

2.

 

Disconnect the inbound 230 V power connectors. 

3.

 

Disconnect the outbound 24 V dc fan power cables. 

4.

 

Remove the screws (1).
