JRR200 Route Reflector Cooling System
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 1. 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.
The fan tray is a field-replaceable unit (FRU)and you can install it without powering off the JRR200 route reflector or disrupting the route reflector function.
