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.
