COOLING – STANDARD VERSION
The 7800FR frame is designed to ensure adequate cooling for up to 360 watts of processing power per
frame. Fans at the front and rear of each power supply module accomplish forced air cooling. Adjacent
equipment may be mounted immediately to the top and bottom of the 7800FR frame. Additional module
cooling is provided by interior cooling channels to ensure that even fully loaded frames mounted vertically
adjacent to each other will operate within the normal temperature range.
For proper cooling, the frame must contain either two 7800PS power supplies,
or one 7800PS power supply and one 7800PS-FM power supply blank panel with
cooling fan.
1.2.1. Fan Exhaust
The cooling fans for the power supplies, located at the front of the frame, draw air in the front and exhaust
out the sides of the frame. The cooling fans for the modules, located at the rear of the frame, draw air in
the front and the exhaust out the rear of the frame.
CAUTION: To ensure adequate cooling, care should be taken to ensure that the
fan inlets and exhaust openings are free of obstructions.
