JRR200 Route Reflector Air Flow and Cooling System
The cooling system for the JRR200 Route Reflector consists of four fan trays located at the rear of the
chassis. Each fan tray contains two fans, so there are a total of eight fans. The fans draw cool air through
vents on the front of the chassis and exhaust the air through the back of the chassis. See
Figure 5 on
page
10. The airflow produced by the fans keeps device components within the acceptable
temperature range.
If any one of the four fan trays fails, the JRR200 route reflector generates a warning but keeps the
system running. If the temperature keeps rising, the JRR200 route reflector lowers the power
consumption by reducing the performance or shutting down some of the chassis components. However,
if the ambient maximum temperature exceeds the warning level and the system cannot be adequately
cooled, then the JRR200 route reflector shuts down the system and hardware components completely.
