Three-Input 240-A Power Supply Load Sharing and Fault Tolerance

When the routing node is operating normally and both power supplies are switched on, load sharing between them occurs automatically. When one power supply fails or is turned off, the other power supply immediately assumes the entire electrical load for the system. A single power supply can provide full power for as long as the routing node is operational. Table 2 on page 7 describes the behavior of the power supply if one of the inputs fails.

Table 2: Fault Tolerance

Input

Three-Input Mode

INPUT 0

If this input fails, INPUT 0, INPUT 1,

 

and INPUT 2 shut down. The power

 

supply shuts down, and the other

 

power supply assumes the electrical

 

load for all three inputs.

INPUT 1

If this input fails, INPUT 0 is

 

unaffected and INPUT 1 and INPUT 2

 

shut down. The other power supply

 

assumes the electrical load of INPUT 1

 

and INPUT 2.

INPUT 2

If this input fails, INPUT 0 is

 

unaffected and INPUT 1 and INPUT 2

 

shut down. The other power supply

 

assumes the electrical load of INPUT 1

 

and INPUT 2.

Two-Input Mode

If this input fails, INPUT 0 and INPUT 1 shut down. The power supply shuts down, and the other power supply assumes the electrical load of INPUT 0 and INPUT 1.

If this input fails, INPUT 0 is unaffected and INPUT 1 shuts down. The other power supply assumes the electrical load of INPUT 1.

Not applicable

Three-Input 240-A Power Supply LEDs

LEDs on each power supply faceplate (see Figure 4 on page 8) indicate the status of the power supply. In addition, a power supply failure triggers the red alarm LED on the craft interface. Table 3 on page 8 describes the functions of the power supply LEDs.

T1600 specifications

Juniper Networks T1600 is a robust, high-performance router designed for service provider and large enterprise networks. As part of Juniper's T series of routers, the T1600 is engineered to facilitate efficient and scalable network operations, making it ideal for environments requiring intensive data traffic management.

One of the T1600's standout features is its capacity to deliver a high level of performance while maintaining reliability. The router supports multiple interfaces, including Ethernet, MPLS, and IPv4/IPv6, allowing for flexible connectivity options tailored to a variety of deployment scenarios. With a forwarding capacity of up to 3.2 terabits per second, the T1600 ensures that network demands are met with ease, even during peak usage.

The T1600 is equipped with advanced technologies that enhance its operational capabilities. Its architecture is built on Juniper's proprietary Junos operating system, which provides a stable and secure platform for managing the various networking protocols. The software enables seamless integration of security, routing, and switching functionalities, reducing the complexity of network management.

Additionally, the router features IPv6 readiness, preparing networks for the next generation of internet traffic. This future-proofing addresses the inevitable exhaustion of IPv4 addresses and caters to the increasing demand for internet-connected devices globally.

Redundancy and fault tolerance are intrinsic to the T1600's design, ensuring continuous operation and minimal downtime. Its modular architecture allows for easy upgrades and replacement of components, facilitating maintenance without significantly impacting network performance.

The T1600 also supports advanced Quality of Service (QoS) features, enabling network administrators to prioritize traffic according to business needs. This capability is crucial for applications that require consistent performance, such as VoIP and video conferencing, where latency and jitter can severely impact user experience.

Scalability is another critical characteristic of the T1600. As network demands grow, organizations can add capacity incrementally, ensuring that infrastructure investments align with evolving requirements.

In summary, Juniper Networks T1600 is a high-capacity, reliable router featuring advanced routing capabilities, robust security, and exceptional redundancy. Its integration of cutting-edge technologies positions it as a powerful solution for enterprises and service providers striving to enhance their networking infrastructure for the future.
