Turn on the Switch

Most 5320 Series switches have one fixed AC power supply unit. The 5320-16P-4XE switch has one fixed DC power supply unit. Be aware of whether the power supply you are connecting is AC-powered or DC-powered. The connection instructions are different depending upon what type of power is used. Follow the instructions in the following sections to connect the appropriate power supply to the switch and turn it on.

Connect AC Power

An AC power cord is not included with the AC power supply. You can purchase AC power cords for use in the US and Canada from Extreme Networks or from your local supplier. The cord must meet the requirements listed in Power Cord Requirements for AC-Powered Switches and AC Power Supplies.

To turn on the switch, connect one end of the power cord to the AC power input socket on the device and connect the other end to an AC power outlet. The switch does not have a power button, so connecting the power cable at both ends turns the switch on. The grounding connection in the power receptacle and in the power cord properly ground the power supply and extend that grounding to the switch.

Connect DC Power

DC power and grounding cables are not included with the power supply. You can purchase #16 AWG copper DC power cables and ground wire for use in the US and Canada from Extreme Networks or from your local supplier.

Use the following instructions to connect the device to a DC power source.

  1. Strip 0.25 inch (6.35 mm) of insulation from one end of each cable wire. Three cable wires are needed: two power input cables and one ground cable.
  2. Verify that the DC circuit is de-energized.
  3. Attach an ESD-preventive wrist strap to your bare wrist and connect the metal end to an appropriate ground point on the rack.
  4. Insert a screwdriver into all three slots on the top of the terminal connector and loosen the screws enough to accommodate a stripped power input cable.
  5. Insert the cable wires into the terminal connector.

    1. Slide the end of the ground wire into the ground terminal (labeled GND on the left side of the connector.
    2. Tighten the screw on the top of the ground terminal connector to 2.2 in‑lb (0.25 N m).
    3. Slide the end of the negative wire (–48 V) into the negative terminal (labeled , in the middle of the terminal connector).
    4. Tighten the screw on the top of the ground terminal connector to 2.2 in‑lb (0.25 N m).
    5. Slide the end of the positive wire (–48 V RTN) into the positive terminal (labeled +, on the right side of the terminal connector).
    6. Tighten the screw on the top of the ground terminal connector to 2.2 in‑lb (0.25 N m).
  6. Insert the connector into the slot on the power supply.

  7. Connect the power cables to the DC source voltage, using hardware appropriate to the installation site and following local and national electrical codes.
  8. Energize the circuit. When power is connected, verify that the PWR LED is green.

When the PWR LED has turned green, follow the instructions in Activate and Verify the Switch.

If the PWR LED does not turn green, refer to 5320 Series Switch LEDs for troubleshooting information.
