Connect a Power Source

Before you begin

Locate the power cord retention strap from the AC power cord bracket and cable clamp kit.

Connect the ExtremeCloud IQ Controller E3125 to a power source if you want to use an external power supply.

Attach the power cord to the power supply module:
1. Insert the locking tab end of the retention strap into the receiver hole of the power supply unit.
  The power supply unit is located to the right of Power Supply #1.
2. Adjust the slider of the retention strap. Push up the locking tab on the bottom of the slider.
3. If you are using another power cord to create an optional redundant power supply, connect the two AC power cords to power supplies #1 and #2. These two power supplies combine and create an optional redundant power supply.
4. Lock the retention strap to the power cord by pulling the slider strap over the power cord.
Plug the other end of the power cords into grounded electrical outlets or to separate power sources, such as an uninterrupted power supply (UPS) or a power distribution unit (PDU).
Power On the controller.
The power button is located on the front control panel.

Note
The power button must be pressed to turn the controller On. The controller is On only when the power button LED is lit.
