Field-Replaceable Units in QFX5120 Switches


Field-replaceable units (FRUs) are components that you can replace at your site. The FRUs in QFX5120 switches are hot-removable and hot-insertable: You can remove and replace them without powering off the switch or disrupting switch functions. The QFX5120 switches have the following FRUs:

  • Power supplies

  • Fan modules

  • Transceivers


Transceivers are not part of the shipping configuration. If you want to purchase any of these components, you must order them separately.


If you have a Juniper J-Care service contract, register any addition, change, or upgrade of hardware components at Failure to do so can result in significant delays if you need replacement parts. This note does not apply if you replace existing components with the same type of component.
