Tools Required for Installation

Chapter 4 Site Planning Considerations

•At least 48 inches (122 cm) of clearance exists between rows of equipment racks. This space is needed to access components in the chassis. Additional clearance may be necessary for installation.

•Enough room exists for the system console terminal, and that the console cable is long enough to reach the routing system from the terminal.

•Fan tray exhaust vents are not blocked, and airflow at the bottom of the chassis is not blocked.

When planning the site, you should think about potential expansion of the system. Consider the following:

•Equipment rack space for additional chassis

•Power and cooling requirements for additional chassis

•Cable management for routing system cables

The following tools are required to install the Cisco CRS-1 8-Slot Line Card Chassis:

•Safety hand truck, pallet jack, or forklift to move the equipment to the installation site. Make sure that the device is capable of preventing the router from tipping. For example, you could use a safety hand truck with retractable safety leg wheels and a security strap, such as the Stevens Appliance Truck Company “Escort,” Model STEV SRT-M-66 (distributed by McMaster-Carr as Model 2654T6) or an equivalent safety hand truck.

•A scissor lift or similar lifting device to position the chassis in the rack and hold the chassis in place while you bolt it to the rack.

•Electric screwdriver or cordless drill (optional, but helpful)

•5/32-inch insert bit that fits 1/4-inch drive extension (preferably magnetic, and one that fits in a cordless drill)

•1/4-inch drive socket

•1/4-inch drive extension and 1/4-inch drive flexible extension, length of 6 inches (15.24 cm)

•Phillips-head number 1 and number 2 screwdrivers

•7-mm wrench or 7-mm nut driver or socket (if unavailable, use 9/32-inch standard tools)

•8-mm wrench

•10-mm wrench

•Crescent wrench

•5/16-inch socket wrench

•M6 hex socket screwdriver

•Large and small socket wrenches

•Allen wrench

•Large, medium, and small Phillips screwdrivers

•Large, medium, and small flat-blade screwdrivers

•ESD-preventive wrist strap

•Antistatic mat

•Scissors

Cisco CRS-1 Carrier Routing System 8-Slot Line Card Chassis Site Planning Guide

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.
