Installing a Fan Tray in a QFX3500 Device
The fan trays in a QFX3500 device are hot-removable and hot-insertable field-replaceable units (FRUs):
you can remove and replace them without powering off the device or disrupting device functions.
CAUTION: Replace a failed fan tray with a new fan tray within 1 minute of removal
to prevent chassis overheating. Before removing the fan tray, ensure you have a
replacement fan tray.
NOTE: The fan tray provides FRU-to-port or port-to-FRU airflow depending on the device model
you purchase.
Before you install a fan tray in a QFX3500 device, ensure that you have taken the necessary precautions
to prevent electrostatic discharge (ESD) damage (see “Prevention of Electrostatic Discharge Damage” on
page 242).
