Each fan tray is a field-replaceable unit (FRU) installed in the rear panel of JRR200 route reflector. You
can remove and replace the fan trays without powering off JRR200 route reflector or disrupting route
reflector functions.
NOTE: All the fan trays must be installed and operational for optimal functioning of JRR200
route reflector.
To replace the fan tray:
1. Identify the physical location of the faulty fan tray on the rear panel of the chassis.
