Figure 320: M320 Router Cooling System Components
The host subsystem monitors the temperature of the router components. When the
router is operating normally, the fans function at lower than full speed. If a fan fails or
the ambient temperature rises above a threshold, the speed of the remaining fans is
automatically adjusted to keep the temperature within the acceptable range. If the
ambient maximum temperature specification is exceeded and the system cannot be
adequately cooled, the Routing Engine shuts down some or all of the hardware
components.
