Field-Replaceable Units in EX4200 Switches

Field-replaceable units (FRUs) are components that you can replace at your site. The FRUs in the switch are:

  • Power supply

  • Fan tray

  • Uplink module

  • Transceivers

Note:

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

The 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/support/tools/updateinstallbase/ . Failure to do so can result in significant delays if you need replacement parts. This note does not apply if you replace existing components with the same type of component.
