Information About Upgrading to a Multishelf System

The difference between upgrading a single-chassis system to a multishelf system and installing a multishelf system is the fabric upgrade. A single-chassis system uses fabric cards designed for single-chassis systems (FC/S cards), and an LCC in a multishelf system uses fabric cards designed for a multishelf system (FC/M cards). On a single chassis system, each fabric card represents one fabric plane. To upgrade a single-chassis system to a multishelf system without interrupting service, you must do the following:

1.Use CLI commands to prepare each FC/S fabric card for replacement with an FC/M card.

2.Shut down the plane on each FC/S card before it is replaced.

3.Replace the FC/S card with an FC/M card.

4.Bring up the FC/M card.

5.Repeat Step 2 through Step 4 until all planes (0 through 7) are upgraded.

When you plan to perform a single-shelf to multishelf system upgrade, consider the following:

•You need these components:

–Fabric card chassis and new line card chassis.

–Cisco Catalyst 6509 Switch, which provides the control Ethernet network for the multishelf system control traffic. We highly recommend two switches for redundancy.

–S13 cards for the original line card chassis (to replace the original S123 cards in the chassis).

–Optical array cables (48 cables for each multishelf system and 24 cables for each line card chassis).

–Additional MSCs and PLIMs for the new line card chassis.

•To avoid traffic loss, you must upgrade the switch fabric one plane at a time. To do that, you must replace each FC/S card with a new FC/M card and restore service to that fabric plane before upgrading the next fabric plane.

•You might want to perform the upgrade during a network maintenance window or when system traffic is light.

Note Be sure to review the upgrade procedures before deciding when to schedule the upgrade. That way, you can familiarize yourself with the upgrade procedure and determine if there are other issues to consider before performing the upgrade.

•Are there cabling issues to consider when you add the new chassis to the existing chassis?

For example, will you have to install optical chassis interconnect cables between the chassis before you bolt the chassis to the floor? If so, be sure to protect the cables while moving the chassis.

How to Upgrade to a Multishelf System

CRS-1 specifications

Cisco Systems' Carrier Routing System (CRS-1) is a cutting-edge, high-capacity router designed to meet the demands of service providers and large enterprises. Introduced in the early 2000s, the CRS-1 represents a significant leap forward in routing technology, offering unparalleled performance, scalability, and reliability.

One of the primary features of the CRS-1 is its exceptional scalability. The system is built on a modular architecture that allows for easy upgrades and expansions. This enables service providers to start with a configuration that suits their immediate needs while having the flexibility to expand as traffic demands grow. The CRS-1 supports a wide range of line cards, enabling data, voice, and video to be managed on a single platform, which simplifies network management and reduces operating costs.

The CRS-1 leverages advanced technologies that enable it to deliver impressive performance. With the ability to handle up to 92 terabits per second of throughput, the router is capable of supporting a vast number of connections, making it well-suited for large-scale service providers and data centers. This level of performance is powered by Cisco’s proprietary silicon technology, which optimizes the packet forwarding process and enhances overall efficiency.

Another key characteristic of the CRS-1 is its strong focus on reliability and redundancy. The system is designed with high availability in mind, ensuring that it can continue to operate seamlessly even in the event of hardware failures. Redundant components, such as power supplies and route processors, allow the CRS-1 to maintain its performance and uptime, a critical requirement for mission-critical network operations.

Additionally, the CRS-1 supports a wide variety of protocols and technologies, including Internet Protocol (IP), Multiprotocol Label Switching (MPLS), and various service provider features. This versatility makes it a compelling choice for organizations looking to implement advanced networking capabilities, such as Quality of Service (QoS) and traffic engineering.

In summary, the Cisco Systems CRS-1 stands out as a formidable solution for modern routing needs. Its modular design, exceptional scalability, robust performance, reliability, and support for multiple protocols and services make it an ideal choice for service providers and enterprises seeking to future-proof their networks. As the demand for bandwidth continues to surge, the CRS-1 remains a pivotal component in the evolution of networking infrastructure.
