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.
