Juniper EX3300 User Manual

NOTE: Grounding is required for DC systems and recommended for AC systems. An AC-powered switch gets
additional grounding when you plug the power supply in the switch into a grounded AC power outlet using the
power cord.
Connecting EX3300 to AC power
The AC power supply has a power cord inlet on the rear panel.
1. Squeeze the sides of the power cord retainer clip and insert the L-shaped ends of the wire clip into the holes in the
brackets next to the power cord inlet on the rear panel.
2. Insert the coupler end of the power cord into the power cord inlet.
3. Push the cord into the slot in the adjustment nut of the power cord retainer. Turn the nut until it is snug against the
base of the coupler and the slot in the nut is turned 90° from the top of the switch.
