The HP FlexFabric 7904 front (port side) to back (power side) airflow
Fan Tray (JG684A) provides powerful cooling and heat dissipation for
the switch. It blows exhaust air out of the switch from the port side to the
power side. The fan tray has five fans and features small size, fast heat
dissipation, and hot swapping. It can automatically adjust the fan speed
based on the switch temperature.
