The FGS chassis has two single-speed fans that operate simultaneously. If one fan fails, it does not affect the

operation of the other fanThe cooling fans cool the CPU, main memory, and voltage regulators. The fans use

either a push or pull configuration to move the air from the left side of the device to the right side of the device as

shown in Figure 6.1.

• Total cooling capacity: 120 watts

• Total air flow: 80 LFM

• Fan operating noise: < 51 dB-A.
