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 modules

  • Transceivers

The power supplies (AC or DC), fan modules, uplink modules, 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.
