Figure 46: Installing a Power Supply in an EX3200 or EX4200 Switch
NOTE: Each power supply must be connected to a dedicated power source outlet.
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.
