Field-Replaceable Units in EX-series Switches

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

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

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

The power supply, fan tray, SFP transceiver, and XFP transceiver in EX-series switches are hot-removable and hot-insertable FRUs: you can remove and replace them without powering off the switch or disrupting switch functions. The uplink module is not hot-removable or hot-insertable: you must power off the switch before removing or installing it.

Note: If you have a Juniper J-Care service contract, register any addition, change, or upgrade of hardware components at 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.
