Replacing the F-MB21X-R Chassis Fan Tray

NOTE You can remove and replace the fan tray without powering off the unit, which allows you to per-
form this maintenance procedure without stopping the service.
However, do so only if you are able to replace the fan tray within five minutes. Otherwise, we recom-
mend that you power off the unit before replacing a fan tray to avoid overheating.

1. Using a flat screwdriver, loosen all five captive screws (
clockwise. Note that the screws are spring-attached to the panel.
2. If an RTU cable is connected, disconnect the cable.
3. Remove the fan tray by pulling it away from the chassis. Set it on an antistatic surface or repack it in packing
materials.
4. Insert a new fan tray in the slot and slide it all the way into the chassis until the captive screws make contact
with the chassis.
5. Tighten the five screws to lock the fan tray into the slot.
6. If the device is powered on, listen for the fans. You should immediately hear them operating. If you do not
hear them, ensure that the fan tray is inserted completely in the chassis.
7. Verify that the Power LED is green. If the LED is not green, one or more fans are faulty. If this problem occurs,
contact your customer service representative for a replacement part.
