Field-Replaceable Units in a J-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 12 on page 21 lists the FRUs for the J-EX8208 switch and their types.
