Field-Replaceable Units in EX4650 Switches
Field-replaceable units (FRUs) are components that you can replace at your site. The FRUs in EX4650
switches are hot-removable and hot-insertable – you can remove and replace them without powering off
the switch. The FRUs in EX4650 switches are:
•
Power supplies
•
Fan modules
•
Transceivers
NOTE: Transceivers are not part of the shipping configuration. If you want to purchase transceivers,
you must order them separately.
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.
