Cabling and Specifications

Step 2 Attach the line card cable-management bracket to the line card as follows:

a.Position the cable-management bracket over the front of the line card faceplate.

b.Insert and tighten the captive screw(s) to secure the bracket to the line card.

c.Starting with the bottom port on the line card, connect each interface cable to the intended port.

Step 3 For multiport line card cable-management brackets, carefully wrap the cables with the supplied Velcro strap. (See Figure 32.)

For single-port line card cable-management brackets, carefully press the interface cable onto the cable clip. (See Figure 33.) Avoid any kinks or sharp bends in the cable.

For information on disconnecting and connecting interface cables, see the “Removing and Installing Fiber-Optic Interface Cables” section on page 52.

Fast Ethernet Interface

The term Ethernet is commonly used for all carrier sense, multiple access/collision detection (CSMA/CD) local-area networks (LANs) that conform to Ethernet specifications, including Fast Ethernet defined by IEEE 802.3u.

IEEE 802.3u specifies the following different physical layers for 100BASE-T:

•100BASE-TX—100BASE-T, half- and full-duplex over Category 5 unshielded twisted-pair (UTP), Electronics Industry Association/Telecommunications Industry Association [EIA/TIA]–568-compliant cable.

Note The 8-Port Fast Ethernet line card provides an RJ-45 connector that follows the Media-Dependent Interface (MDI) port wiring standard, as opposed to the Media-Dependent Interface-crossed (MDI-X) wiring scheme found on many hubs and repeaters.

XR 12000 Series specifications

The Cisco Systems XR 12000 Series routers are designed to meet the demands of modern networking environments, ensuring high performance, scalability, and reliability for service providers and large enterprises. This series is engineered to deliver advanced features that facilitate a range of applications, including core routing, edge services, and data center interconnect.

One of the main features of the XR 12000 Series is its advanced routing capabilities. These routers utilize the Cisco IOS XR software architecture, which provides a modular and distributed operating system. This architecture enhances system reliability as individual processes can be restarted independently without affecting overall system operations. As a result, service providers can achieve higher uptime and enhanced service continuity.

The XR 12000 Series supports a robust set of technologies that enable efficient data handling and transport. Notably, the series includes support for Multiprotocol Label Switching (MPLS), which enhances traffic engineering, distributed bandwidth management, and Quality of Service (QoS) capabilities. This makes the XR 12000 a preferred choice for operators looking to optimize their network performance under increasing traffic loads.

Furthermore, the XR 12000 Series excels in scalability. With a flexible modular design, operators can customize their systems to fit specific needs by adding additional line cards or service modules. These enhancements enable operators to scale both up and down based on fluctuating demands, accommodating numerous high-bandwidth applications such as video streaming, cloud services, and IoT.

Security is another critical characteristic of the XR 12000 routers. Built-in cybersecurity features, including secure boot, strong encryption, and integrity checks, protect against unauthorized access and ensure data integrity. Coupled with advanced monitoring and logging capabilities, these routers can help operators maintain robust security postures.

Additionally, the XR 12000 Series is designed to facilitate seamless integration with existing network infrastructures. The routers support various protocols and interfaces, which ensure interoperability with legacy systems and enhance overall network efficiency. This flexibility allows service providers to future-proof their investments while adapting to evolving technological landscapes.

In summary, the Cisco XR 12000 Series routers stand out for their advanced routing capabilities, scalability, robust security features, and compatibility with modern and legacy network infrastructures. These attributes make them an ideal choice for organizations seeking to enhance their networking capabilities in a rapidly changing digital environment.
