QFX10000 Field-Replaceable Units
Field-replaceable units (FRUs) are switch components that you can replace at your site. The switch uses
these types of FRUs:
• Hot-insertable and hot-removable—You can remove and replace these components without powering
off the switch or disrupting the switching function.
• Hot-pluggable—You can remove and replace these components without powering off the switch, but
the switching function is interrupted until you replace the component.
Table 80 on page 230 lists the FRUs and their types for the QFX10000.
