Field-Replaceable Units in an EX8208 Switch

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 8 on page 35 lists the FRUs for the EX8208 switch and their types.
