• Ensure you understand how to prevent electrostatic discharge (ESD) damage. See
Electrostatic Discharge Damage

The fan tray in an EX9200 switch is a hot-insertable and hot-removable field-replaceable unit (FRU): You
can remove and replace it while the switch is running without turning off power to the switch or
disrupting switching functions.
CAUTION: Do not remove the fan tray unless you have a replacement fan tray
available.
