Installing a Fan Module in a QFX5110
The fan modules in a QFX5110 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: Replace a failedfanmodule with a newfanmodule within 1 minute
of removal to prevent chassis overheating. Before removing the fan module,
ensure you have a replacement fan module at hand.
