Turn on the Switch

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 an Extreme Networks switch, do the following.

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.
For switches that are connected to DC power, do the following:
1. Verify that the DC circuit is de-energized.
2. Verify that the ground wire is connected to the grounding lug on the rear of the switch.
  The grounding lug is identified by the international symbol for earth ground:
3. Verify that the DC power input cables are properly connected to the DC power supplies at the rear of the switch.
4. Energize the circuit.
When power is connected, verify that the PSU LED turns green.

When the PSU LED has turned green, follow the instructions in Connect Network Interface Cables.

If the PSU and RPS LEDs do not turn green, refer to the LEDs topic for your switch model (in 5520 Series Switch LEDs) for troubleshooting information.
