Connecting AC Power to an EX3300 Switch

The power supply is built in along the rear panel, with an AC power cord inlet on the rear panel.

Ensure that you have the following parts and tools available:

  • A power cord appropriate for your geographical location
  • A power cord retainer clip

Ensure that you have connected the switch chassis to earth ground.

Caution: To meet safety and electromagnetic interference (EMI) requirements and to ensure proper operation, you must connect the switches to earth ground before you connect them to power. For installations that require a separate grounding conductor to the chassis, use the protective earthing terminal on the switch chassis to connect to the earth ground. For instructions on connecting earth ground, see Connecting Earth Ground to an EX Series Switch. An EX3300 switch gets additional grounding when you plug the power supply in the switch into a grounded AC power outlet by using the AC power cord appropriate for your geographical location (see AC Power Cord Specifications for EX3300 Switches).

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 by using the AC power cord appropriate for your geographical location.

To connect AC power to the switch:

  1. 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 (Figure 35).

    The power cord retainer clip extends out of the chassis by 3 in.

  2. 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 EX3300 Switches.

    Warning: Ensure that the power cord does not drape where people can trip on it or block access to switch components.

  3. Insert the coupler end of the power cord into the AC power cord inlet on the rear panel.
  4. Push the power cord into the slot in the adjustment nut of the power cord retainer clip. 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 36).
  5. If the AC power source outlet has a power switch, set it to the OFF (0) position.
  6. Insert the power cord plug into an AC power source outlet.
  7. If the AC power source outlet has a power switch, set it to the ON (|) position.
