The MX10016 cooling system components work together to keep all components within the acceptable
temperature range. If the maximum temperature specification is exceeded and the system cannot be
adequately cooled, the Routing and Control Board shuts down some or all of the hardware components.

The cooling system in an MX10016 chassis consists of two fan trays and two fan tray controllers. An
MX10016 has an air filter on the front panel. The fans in each fan tray are numbered 0 through 10.
Two fan tray models and their associated fan tray controllers are available. All models are hot-insertable
and hot-removable. See Table 9 on page 45.
