Installing a Fan Module in an EX4600 Switch
The fan modules in an EX4600 switch are hot-removable and hot-insertable
field-replaceable units (FRUs): you can remove and replace them without powering off
the switch or disrupting switch functions.
CAUTION: Replacea failed fan module with a new fan module within 1 minute
of removal to prevent chassis overheating. Before removing the fan module,
ensure you have a replacement fan module at hand.
