Table 3-2 8-Slot Line Card Chassis and Equipment Rack Specifications (continued)

Equipment Rack Specifications (continued)

Mounting Rails and Hardware

 

Rail openings (aperture)

17.75 in. (45.1 cm), side to side

 

22.8 in. (57.9 cm), front to back (adjustable or fixed)

Horizontal mounting rails

The equipment rack should contain horizontal mounting rails to

 

place the chassis on. The mounting rails, which must be able to hold

 

at least 650 lb (294.8 kg), support the weight of the chassis.

 

ESW 27 racks are equipped with horizontal mounting rails

 

already installed. Place the chassis on these rails.

 

For other types of racks, a set of brackets is included in the

 

chassis installation kit, which is available as an option

 

(CRS-8-INSTALL-KT=). Install these brackets and place the

 

chassis on them. For details, see the Cisco CRS-1 Carrier

 

Routing System Line Card Chassis Unpacking, Moving, and

 

Securing Guide.

 

Note In addition to supporting the chassis, the mounting rails are

 

also designed to space adjustable rack rails at 22.8-inches (front

 

to back) for chassis installation.

Mounting holes

EIA standard mounting-hole spacing:

 

18.25-inches to 18.31-inches (46.36 to 46.51 cm),

 

center-to-center horizontal spacing

 

0.5 + 0.625 + 0.625-inches (1.27 + 1.59 + 1.59 cm),

 

vertical-hole-spacing pattern; repeats on 1.75-inch (4.45 cm)

 

pitch ETSI racks have mounting rails with EIA standard

 

spacing.

Mounting screws

48 screws for each chassis, 12 screws in each of 4 vertical rails,

 

installed in holes with tick marks

 

No. 10-32 screws (provided with the chassis)

 

No. 10-24 or M5 screws can be used if rack thread pitch allows.

 

Note If you plan to use mounting screws other than the ones

 

shipped with the chassis, make sure that the screws are made

 

of stainless steel or a hard alloy. Do not use screws made of

 

soft alloy steel.

 

 

Compliance

Make sure that the rack complies with all appropriate standards for

 

your geographical area—for example, NEBS Seismic Zone 4

 

(GR-63-CORE, Sections 4.4.1 and 4.4.2).

 

Note The 8-slot chassis has passed Cisco Zone 4 seismic testing in

 

an ESW 27 rack (part number F-01941-01).

 

 

Additional Rack Considerations

 

Interface cables

When choosing a rack, consider cabling needs (chassis front). Allow

 

at least 95 lb (43.1 kg) weight for each chassis for cables.

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.
