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 9 on page 23 lists the FRUs for the EX8208 switch and their types.
