Installing and Removing EX4300 Switch Hardware Components
The EX4300 switch chassis is a rigid sheet-metal structure that houses the hardware
components. The field-replaceable units (FRUs) in EX4300 switches are:
•
Power supplies
•
Fan modules
•
Uplink module
•
Transceiver
The power supply (AC or DC), fan module, uplink module, and transceivers are
hot-removable and hot-insertable: You can remove and replace them without powering
off the switch or disrupting switch functions.
NOTE: You must remove a fan module only for replacement.
