PWR-RGD-AC-DC-H Hot-Plug Power Supplies

Yes, when properly tested. Terabit Systems runs every unit through a 5-step Quality Assurance and testing process before shipping, checking functionality, electrical safety, and performance under load. Combined with a 1-year warranty, refurbished power supplies offer the same reliability as new OEM units at a significantly lower cost.

Wattage requirements depend on your switch or router model, the number of populated ports, and any Power over Ethernet (PoE) demands. Check your device's technical documentation for the recommended AC or DC power supply wattage, or contact our technical support team with your model number for a compatibility recommendation.

Most Cisco and Juniper platforms support mixed power supply configurations, but total available power will be limited to the lowest-rated unit's specification unless the system is designed for asymmetric load sharing. Always consult the specific device's installation guide before combining different wattage power supplies for redundancy.

If a unit is found defective during the warranty period, Terabit Systems' Return Merchandise Authorization (RMA) process applies. Customers contact support to initiate the RMA, and a replacement or refund is issued once the defect is confirmed, backed by Terabit Systems' warranty on Cisco and Juniper hardware.

Power cords are typically sold separately for most AC power supply units, including Juniper EX-PWR and PWR-MX960 series products. Be sure to add a compatible power cord to your order, or contact support to confirm cord compatibility with your specific installation.

N+1 redundancy means installing one more power supply than the minimum required to run the system, so that if one unit fails, the device continues operating without interruption. Hot-plug power supplies make N+1 redundancy practical, since a failed unit can be swapped out live without taking the network device offline.
