JPSU-920-AC-AFO Power Supplies

Yes. Refurbished units sold by Terabit Systems undergo a 5-step quality assurance and testing process before shipment, verifying functionality, output stability, and protection circuitry. Each unit is backed by a 1-year warranty, giving buyers confidence comparable to purchasing new equipment at a significantly lower cost.

Front-to-back (AFO) airflow pulls air in from the port side and exhausts it out the rear, matching the cooling direction of many data center hot-aisle/cold-aisle layouts. Choosing the correct airflow direction is critical to prevent overheating and ensure compatibility with adjacent equipment in a rack.

Power cords are typically sold separately from the power supply unit itself, as noted in the technical specifications for models like the PWR-MX960-4100-AC-S. Buyers should confirm cord requirements, such as connector type and voltage rating, before ordering to ensure full compatibility with their installation.

Juniper AC power supplies typically include overcurrent protection, overvoltage protection, and short-circuit protection. These safeguards help prevent damage to connected networking equipment and improve overall system reliability, which is especially important in continuously operating data center and service provider environments.

Terabit Systems offers a Return Merchandise Authorization (RMA) process for defective units discovered during the warranty period, along with a 1-year replacement or full refund guarantee. Customers should contact technical support via phone or live chat to initiate an RMA and confirm return eligibility.

Refurbished Juniper AC power supplies, such as the JPSU-350-AC-AFO, can achieve up to 90% power efficiency. Higher efficiency reduces wasted energy as heat, lowering operating costs and cooling demands in dense data center racks running multiple switches and routers continuously.
