Replacing the JRR200 Route Reflector Fan Tray
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.
Figure 15 on page 54 shows how the fan trays are numbered.

2.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect
the strap to the ESD point on the chassis.
3.
Loosen the captive screws on the fan tray faceplate.
4.
Grasp the captive screw and pull out the fan tray completely out of the chassis.
