To connect earth ground to a switch:
1. Before you connect power to the switch, wrap and fasten one end of an ESD wrist strap around your bare wrist, and
connect the other end of the strap to the ESD point on the switch.
To connect power to an AC-powered switch (see Figure 7):
Figure 7: Connecting Power to a EX4650 Switch Powered by AC Power Supply
1. Push the end of the retainer strip into the hole next to the inlet on the power supply faceplate until it snaps into place.
2. Press the tab on the retainer strip to loosen the loop. Slide the loop until you have enough space to insert the power
cord coupler into the inlet.
3. Insert the power cord coupler firmly into the inlet.
4. Slide the loop toward the power supply until it is snug against the base of the coupler.
5. Press the tab on the loop and draw out the loop into a tight circle.
6. If the AC power source outlet has a power switch, set it to the OFF (O) position.
NOTE: The switch powers on as soon as power is provided to the power supply. There is no power switch
on the switch.
7. Insert the power cord plug into the power source outlet.
8. Verify that the AC and DC LEDs on the power supply are lit green. If the fault LED is lit, remove power from the power
supply, and replace the power supply.
