Field-Replaceable Units in a QFX3008-I Interconnect Device
Field-replaceable units (FRUs) are device components that you can replace at your site. The QFX3008-I Interconnect device FRUs except the master Control Board are hot-insertable and hot-removable: you can remove and replace them without powering off the device or disrupting the switching function.
