Note When shipped with spare line card orders, the cable-management bracket is not attached to the line card. You must attach the cable-management bracket to the line card before you insert the line card into the router.

Caution Do not use the cable-management bracket as a handle to pull out or push in the line card. The cable-management bracket is designed to hold the interface cables and may break if you use the bracket to push, pull, or carry the line card after it is removed from the router.

Removing and installing the line card cable-management bracket is described in the following procedures:

Removing a Line Card Cable-Management Bracket

To remove a line card cable-management bracket, follow these steps:

Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.

Step 2 Note the current interface cable connections to the ports on each line card.

Step 3 Starting with the interface cable for the bottom port on the line card, disconnect the cable from the line card interface.

Note It is not necessary to remove the interface cables from the line card cable-management bracket. The bracket (with attached cables) can be hooked to the cable-management tray or a bracket on the chassis until a new line card is installed.

Step 4 For multiport line card cable-management brackets, proceed upward and remove the interface from the Velcro strap on the end of the cable standoff. (See Figure 32.)

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

Step 5 Repeat Step 3 and Step 4 for all remaining interface cables, then proceed to Step 6.

Step 6 For multiport line card cable-management brackets, loosen the captive installation screw at each end of the cable-management bracket and remove the bracket from the line card.

For single-port line card cable-management brackets, loosen the captive installation screw on the cable-management bracket and remove the bracket from the line card.

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.
