Connecting Power to the Switch

1. For switches that are connected to AC power, connect the power cord to the AC power input socket on the switch (or power supply) and to an AC power outlet.
2. For switches that are connected to DC power, do the following:
   1. Verify that the DC circuit is de-energized.
   2. Identify the grounding lug on the rear of the switch.
      The grounding lug is identified by the international symbol for earth ground:
   3. Connect the spade terminal end of the ground wire to the grounding lug with the M4x0.7 screw provided. Connect the other end to a reliable earth ground.
      Use stranded copper wire, sized between 14 AWG and 6 AWG.
   4. Using a cross-head (Phillips) torque screwdriver, tighten the retaining screw to 20 in‑lb (2.25 N m).
   5. Connect the DC power input cables to the DC input terminal block on the rear of the switch.
   6. Energize the circuit.
3. If applicable, attach the cable from your redundant power supply (RPS) into the switch‘s redundant power supply receptacle.
4. When power is connected, verify that the PSU LED and RPS LED (if applicable) turns green.
