Installing and Removing QFX3500 Device Hardware Components
The QFX3500 device chassis is a rigid sheet-metal structure that houses the hardware components. The
field-replaceable units (FRUs) in QFX3500 devices are:
Power supply
Fan tray
Management board
SFP transceiver
SFP+ transceiver
QSFP+ transceiver
All of the QFX3500 device FRUs except the management board are hot-insertable and hot-removable:
you can remove and replace them without powering off the device or disrupting device functions. You
must power off the QFX3500 device before replacing the management board.
CAUTION:
within 1 minute of removal to prevent chassis overheating. Replace a failed fan tray
with a new fan tray within 1 minute of removal to prevent chassis overheating.
Replace a failed power supply with a blank panel or new power supply
