Figure 7. AT-FAN08 Module
The chassis comes with two pre-installed fan modules in FAN A and FAN
B slots on the rear panel. The air flow is from the front to the back of the
chassis, with the fans drawing air out of the device.
The fan module has two fans. The switch automatically adjusts the speeds
of the fans, depending on its internal temperature.
The AT-FAN08 modules are field-replaceable and hot-swappable. You do
not have to power off the switch to replace them.
