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.
