  Meghan CampbellJul 26, 2025
  If your Juniper Gateway is not receiving power, first, check the AC power cord for any damage such as cracks or breaks in the insulation, and replace it immediately if damaged. Ensure that the power socket you are using is functioning correctly. Also, verify that the device's AC input voltage is between 100 and 240 VAC. If these steps do not resolve the issue, further assistance may be needed.
