Product Review

The Juniper JPSU-1600W-DC-AFO power supply, designed for the PTX1000, offers a significant 3 Tbps system throughput and forwarding capacity up to 2 Bpps, ensuring efficient handling of high-volume network traffic. Its power efficiency at 0.4 watts per Gbps and the inclusion of four 1600 watt power supplies with hot-swappable redundant fans highlight its capability for continuous, reliable operation. However, the device's substantial weight of 68 lb and a maximum power draw of 1425 W may necessitate careful consideration of rack space and power infrastructure in data center environments.


The Juniper JPSU-1600W-DC-AFO is a high-capacity DC power supply designed for the PTX1000 router, delivering efficient and reliable power for demanding network environments. This power supply unit (PSU) offers a maximum output of 1600 watts, supporting the router's operations and ensuring optimal performance across a range of conditions. The JPSU-1600W-DC-AFO is engineered to meet the needs of networks requiring high throughput and forwarding capacity, with a system throughput of 3 Tbps and a forwarding capacity of up to 2 Bpps. Key hardware specifications of the Juniper JPSU-1600W-DC-AFO include its support for a diverse range of Ethernet port densities, accommodating up to 288 10GbE ports, 72 40GbE ports, and 24 100GbE ports. This flexibility allows network administrators to scale their systems according to the specific demands of their network, without compromising on power or performance. The power supply itself is housed within a 2U rack-mountable form factor, measuring 17.4 inches in width, 3.46 inches in height, and 31 inches in depth, and weighs 68 pounds. At the heart of the PTX1000 router, powered by the JPSU-1600W-DC-AFO, is an Intel Quad Core Ivy Bridge CPU operating at 2.5 GHz, accompanied by 32 Gb of SDRAM. This powerful combination facilitates the handling of large volumes of data with efficiency, supporting the router's high-speed data processing capabilities. The system's maximum power draw is rated at 1425 W, with a typical power draw of 1050 W, translating to a power efficiency of 0.4 watts per Gbps.
  • Maximum power draw: 1425 W, equating to 4862 BTU/hr.
  • Typical power draw: 1050 W, equating to 3583 BTU/hr.
  • Power supply configuration: 4x1600 watts (AC/DC).
Cooling is managed by three hot-swappable redundant fans, ensuring the system remains operational even in the event of a fan failure. This front-to-back cooling mechanism helps to maintain optimal operating temperatures, ranging from 32° to 115° F, and storage temperatures between -40° and 158° F. The PTX1000, equipped with the JPSU-1600W-DC-AFO, is designed to operate at altitudes of up to 10,000 feet and can withstand relative humidity levels from 5 to 90% during operation, and 5 to 95% during non-operating periods. With a packet buffer of 24 Gb, the router efficiently manages data traffic, ensuring minimal latency. The latency within the Packet Forwarding Engine is 2.5 μs, and 5 μs between Packet Forwarding Engines, facilitating swift data processing and transfer across the network. This performance is critical for applications requiring high-speed data transmission and real-time communication.
