The air intake to cool the chassis flows through the perforations in the front of the chassis. Hot air exits from
the rear of the chassis via the vents provided near the fans. See Figure 2.

Temperature sensors in the chassis monitor the internal chassis temperature. When a single fan/fan tray fails
at room temperature, the system can still provide sufficient cooling.
If a fan/fan tray fails or if the ambient temperature inside the chassis rises above the acceptable range, the
router raises an alarm. If the temperature inside the chassis rises above the maximum threshold temperature,
the router shuts down automatically.
