Rack Selection Guidelines

Chapter 3 Preparing Your Site for Installation

Site Planning

The Cisco 1000 Series Router can be mounted in most two-post or four-post, 19-inch equipment racks that comply with the Electronics Industries Association (EIA) standard for equipment racks (EIA-310-D 19-inch). The rack must have at least two posts with mounting flanges to mount the chassis.

Caution When mounting a chassis in any type of rack equipment, make certain the inlet air to the chassis does not exceed 55C.

The distance between the center lines of the mounting holes on the two mounting posts must be 18.31 inches ± 0.06 inch (46.50 cm ± 0.15 cm). The rack-mounting hardware included with the chassis is suitable for most 19-inch equipment racks.

We recommend that you mount the Cisco 1000 Series Router in an equipment rack which includes the necessary rack-mounting hardware which is suitable for most 19-inch equipment racks.

Consider installing the Cisco 1000 Series Router in a rack with the following features:

•NEBS compliant, 19-inch (48.3 cm) wide rack.

•EIA or ETSI hole patterns in the mounting rails. Required mounting hardware is shipped with the Cisco 1000 Series Router. If the rack that you plan to install the system in has metric-threaded rails, you must provide your own metric mounting hardware.

•Perforated top and open bottom for ventilation to prevent overheating.

•Leveling feet for stability.

Note The Cisco 1000 Series Router should not be installed in an enclosed rack because the chassis requires an unobstructed flow of cooling air to maintain acceptable operating temperatures for its internal components. Installing the router in any type of enclosed rack—even with the front and back doors removed—could disrupt the air flow, trap heat next to the chassis, and cause an overtemperature condition inside the router. If you use an enclosed rack, make certain that there are air vents on all sides of the rack and there is proper ventilation.

Equipment Rack Guidelines

The placement of the rack can affect personnel safety, system maintenance, and the system ability to operate within the environmental characteristics described in Table 3-2 on page 3-7. Choose a proper location for the Cisco 1000 Series Router by following the guidelines below.

Locating for Safety

If the Cisco 1000 Series Router is the heaviest or the only piece of equipment in the rack, consider installing it at or near the bottom to ensure that the rack’s center of gravity is as low as possible.

For additional information about the proper placement of electronic equipment, consult the document GR-63-CORE, Network Equipment Building System (NEBS) Requirements: Physical Protection.

Locating for Easy Maintenance

Keep at least 3 feet of clear space in front and behind the rack. This space ensures that you can remove the Cisco 1000 Series Router components and perform routine maintenance and upgrades easily.

ASR1000 specifications

The Cisco ASR 1000 Series Aggregation Services Routers are designed to meet the needs of enterprises and service providers seeking high-performance networking solutions. With a combination of scalability, reliability, and security, these routers provide an ideal platform for delivering a wide range of services in a compact form factor.

One of the standout features of the ASR 1000 is its embedded hardware architecture. It utilizes a unique Distributed Services Architecture that allows for greater resource allocation and management, resulting in enhanced performance across various applications. This architecture enables the router to dynamically balance workloads across multiple CPUs, ensuring optimal resource utilization and reducing latency.

The ASR 1000 Series supports a variety of interfaces, including Ethernet, T1/E1, and T3/E3, making it highly versatile for different connectivity options. With support for up to 200 Gbps of throughput, it can handle the growing demands of modern networks, including video conferencing, cloud applications, and data-intensive services.

Security is a paramount feature of the ASR 1000. The routers come equipped with advanced security technologies such as Cisco IOS XE software, which includes built-in encryption and secure access controls. This ensures that data remains protected in transit, allowing organizations to safeguard sensitive information while maintaining compliance with industry regulations.

Another key characteristic of the ASR 1000 is its modularity. Users can easily add or upgrade services through service modules and network interface modules, providing the flexibility needed to adapt to changing network requirements. This modular approach not only helps in managing costs but also extends the life cycle of the hardware.

In terms of manageability, the ASR 1000 Series incorporates Cisco’s Intelligent Network Services, providing comprehensive monitoring and troubleshooting capabilities. This allows network administrators to gain insights into network performance, optimize service delivery, and promptly address any issues that arise.

Finally, the ASR 1000 routers are designed for high availability, featuring redundant power supplies and fans. Coupled with advanced routing protocols and features such as Cisco’s Continuous Availability, the ASR 1000 ensures minimal downtime and uninterrupted service delivery.

In conclusion, the Cisco ASR 1000 Series Aggregation Services Routers combine performance, scalability, security, and manageability, making them an excellent choice for organizations looking to modernize their networking infrastructure while efficiently handling the demands of contemporary applications. Whether for enterprise networks or service provider environments, the ASR 1000 provides a robust and future-proof solution.
