Upgrading the DC Power Supplies

Upgrading the DC Power Supplies

NOTE: You must upgrade both power supplies. Follow these procedures for one power supply, then immediately upgrade the other power supply. Mixing a two-input 160-A power supply and a three-input 240-A power supply is supported only during the upgrade.

The power supplies are located at the lower rear of the chassis. Each power supply is hot-insertable and hot-removable. When one power supply is powered down or removed, the other power supply automatically assumes the entire electrical load for the routing node. To upgrade each two-input 160-A power supply to a three-input

240-A power supply, use the following procedures:

Preparing the DC Power Cables on page 17

Tools and Parts Required on page 17

Removing a Two-Input160-A Power Supply on page 18

Setting the Input Mode Switch on a Three-Input240-A Power Supply on page 21

Installing a Three-Input240-A Power Supply on page 22

Replacing the Cable Restraint on a Three-Input240-A Power Supply on page 23

Connecting a Three-Input240-A Power Supply on page 25

Powering On a Three-Input240-A Power Supply on page 26

Preparing the DC Power Cables

The accessory box shipped with the installation kit includes the cable lugs that attach to the terminal studs of each power supply (see Figure 25 on page 46).

CAUTION: Before the power supply installation begins, a licensed electrician must attach cable lugs to the power cables that you supply. A cable with an incorrectly attached lug can damage the power supply.

Tools and Parts Required

To upgrade the power supplies, you need the following tools and parts:

Four additional DC power cables (two cables for each power supply)

Electrostatic discharge (ESD) grounding wrist strap

7/16-in. nut driver or pliers

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.
