b) Simultaneously press the latches, and pull the fan module fully out of the chassis.
c) Pull the fan module clear of the chassis.
Step 2
To install a fan module, follow these steps:
a) Hold the fan module with the LED and PID label at the top.
b) Align the fan module to the open fan tray slot in the chassis and press the module all the way into the slot until the
left and right latches click and locked on the chassis.
Note
If the fan module does not go all the way into the slot, do not force it. Remove the fan module and verify
that it is the correct type for your router and in the correct orientation.
c) If the chassis is powered on, listen for the fans. You should immediately hear them operating. If you do not hear
them, ensure that the fan module is inserted completely in the chassis.
d) Verify that the fan module LED is green. If the LED is not green, one or more fans are faulty. If this situation occurs,
contact your customer service representative for replacement parts.
