Field-Replaceable Units in an EX9200 Switch

Field-replaceable units (FRUs) are switch components that you can replace at your site. The EX9200
switch uses the following 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 6 on page 26 lists the FRUs for the EX9200 switch and their types.
