Power supplies for the J-EX8216 switch are fully redundant, load-sharing, and
hot-insertable and hot-removable field-replaceable units (FRUs). Each J-EX8216 switch
chassis can hold up to six 2000 W AC or six 3000 W AC power supplies.
The 2000 W AC power supplies support both low-voltage line (100–120 VAC) and
high-voltage line (200–240 VAC) AC power configurations on a J-EX8216 switch.
Each 3000 W AC power supply delivers 3000 W of power at high voltage (200–240
VAC) to the J-EX8216 chassis. Low-voltage input is not supported for the 3000 W AC
power supplies on the J-EX8216 switch.
The redundant AC configuration ships with six AC power supplies to provide the capacity
to power the system using N+1 or N+N power redundancy. See AC Power Supply in a
J-EX8200 Switch and J-EX8216 Switch Configurations.
CAUTION: Mixing different types of power supplies in the same chassis is
not a supported configuration.
