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.
To prevent data loss on the Interconnect cards, we recommend that you follow the procedures to offline and power off the cards before removing them from the device. See Table 1 for details.
Table 1 lists the FRUs for the QFX3008-I Interconnect device and actions to take before removing them.
