Juniper Networks EX4200 - Manual (Page 173)

NOTE: Each power supply must be connected to a dedicated power source outlet.
To connect AC power to an EX3200 or EX4200 switch:
1. Ensure that the power supplies are fully inserted in the chassis and the screws
on their faceplates are tightened.
2. Squeeze the two sides of the power cord retainer clip and insert the L-shaped
ends of the wire clip into the holes in the bracket on each side of the AC power
cord inlet on the AC power supply faceplate (see Figure 54 on page 147).
3. Locate the power cord or cords shipped with the switch; the cords have plugs
appropriate for your geographical location. See “AC Power Cord Specifications
for EX3200 and EX4200 Switches” on page 98.
WARNING: Ensure that the power cord does not block access to switch components
or drape where people can trip on it.
4. Insert the coupler end of the power cord into the AC power cord inlet on the AC
power supply faceplate.
5. Push the cord into the slot in the adjustment nut of the power cord retainer. Turn
the nut until it is tight against the base of the coupler and the slot in the nut is
turned 90° from the top of the switch (see Figure 55 on page 148).
6. If the AC power source outlet has a power switch, set it to the OFF (0) position.
7. Insert the power cord plug into an AC power source outlet.
8. If the AC power source outlet has a power switch, set it to the ON (|) position.
9. Verify that the AC OK LED on the power supply is lit and is on steadily.
