Installing and Removing EX9208 Switch Hardware Components
The field-replaceable units (FRUs) in an EX9208 switch are:
•
Routing Engine module (RE module)
•
Switch Fabric module (SF module)
• Power supplies (AC and DC)
• Fan tray
•
Line cards

SFP, SFP+, QSFP+, and CFP transceivers
The RE module and SF module are hot-removable or hot-pluggable depending on the
configuration of the switch. See

All the line cards are hot-removable and hot-insertable. However, we recommend that
you take them offline before removing them.
The AC and DC power supplies, fan tray, and the SFP, SFP+, and QSFP+ transceivers in
EX9200 switches are hot-removable and hot-insertable FRUs: You can remove and
replace them without powering off the switch or disrupting switch functions.
