Field-Replaceable Units in EX3200 and EX4200 Switches

Field-replaceable units (FRUs) are components that you can replace at your site. The field-replaceable units (FRUs) in EX3200 and EX4200 switches are:

  • Power supply
  • Fan tray
  • Uplink module
  • SFP transceiver
  • SFP+ transceiver
  • XFP transceiver

Note: Uplink modules are not part of the standard package and must be ordered separately.

The power supply, fan tray, 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: If you have a Juniper J-Care service contract, register any addition, change, or upgrade of hardware components at https://www.juniper.net/customers/csc/management/updateinstallbase.jsp. Failure to do so can result in significant delays if you need replacement parts. This note applies if you change the type of power supply or add a new type of uplink module. It does not apply if you replace these components with the same type of component.
