The QFX10008 and QFX10016 chassis have two independent, field-replaceable fan trays.
Each fan tray is a hot-removable and hot-insertable field-replaceable unit (FRU); you
can remove and replace the fan tray while the switch is running without turning off power
to the switch or disrupting switching functions.
Before you begin to install a fan tray:
