Power supply RUIJIE RG-NIS-PA120-54 120W, AC 100–240V, 50/60Hz, -40–70°C, 125×35×110mm, 480g

The Ruijie Networks RG-NIS-PA120-54 120W power supply provides stable DC power for compatible Ruijie network switches. With a rated output of 120 watts and comprehensive protection against over-current, over-voltage, overheating and short circuits, the unit is engineered for reliable operation in rack or wall-mounted network environments. It accepts a wide AC input range of 100–240 V at 50/60 Hz and has compact dimensions (35 mm × 110 mm × 125 mm) that simplify placement in constrained spaces.

Advantages

This power supply delivers a consistent 120W output while incorporating multiple protection mechanisms to safeguard connected equipment and improve operational uptime. Its universal AC input reduces the need for regional variants, and the compact footprint allows flexible installation close to network switches. The combination of silver, blue and black finishes provides a neutral aesthetic suitable for most professional networking setups.

How to use

Connect the power supply to a compatible Ruijie network switch following the manufacturer's installation guidance. Ensure the AC input is within the specified 100–240 V range and that the outlet and cabling meet local electrical codes. Mount the unit in a location that allows adequate ventilation and keeps heat sources away. Verify the switch recognizes the external supply and monitor for normal operation after power-up.

Recommendations

Install the power supply in a dry, dust-free environment with ambient temperature within the switch manufacturer's specified limits. Use properly rated cabling and, if used for redundant power, label connections to avoid confusion during maintenance. Periodically inspect for loose connections and signs of overheating.
