Equipment Racks

General Site Requirements

The following tips will help you plan an acceptable equipment rack conﬁguration:

•Enclosed racks must have adequate ventilation. Ensure that the rack is not overly congested because each unit generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air.

•When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or the exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated all the way into the rack.

•In an enclosed rack with a ventilation fan in the top, excessive heat generated by equipment near the bottom of the rack can be drawn upward and into the intake ports of the equipment above.

•Bafﬂes can help to isolate exhaust air from intake air, which also helps to draw cooling air through the chassis. The best placement of the bafﬂes depends on the airﬂow patterns in the rack, which can be found by experimenting with different conﬁgurations.

•When equipment installed in a rack, particularly in an enclosed rack, fails, try operating the equipment by itself, if possible. Turn off other equipment in the rack (and in adjacent racks) to allow the unit under test a maximum of cooling air and clean power.

Power Supply Features

Following are features of the router power supply:

•

Autoranging power supply (200W, 100 to 240 VAC, 50 to 60 Hz, 40 to 72 VDC)

6-foot electrical power cord

Warning Do not touch the power supply when the power cord is connected. For systems with a power switch, line voltages are present within the power supply even when the power switch is off and the power cord is connected. For systems without a power switch, line voltages are present within the power supply when the power cord is connected.

2-6Cisco 4000 Series Installation Guide

4000 specifications

Cisco Systems 4000 Series routers are a robust and versatile line of devices designed to meet the demands of modern enterprise networks. These routers are tailored for high performance and scalability, making them suitable for both branch offices and data centers. The 4000 Series introduces a wide array of features and technologies aimed at enhancing connectivity, security, and operational efficiency.

At its core, the Cisco 4000 Series provides advanced routing capabilities with support for a variety of routing protocols. This versatility enables businesses to seamlessly integrate with existing network infrastructures while setting the stage for future growth. The routers support both traditional WAN connectivity and modern software-defined WAN (SD-WAN), allowing businesses to utilize a mix of technologies according to their needs.

One of the standout features of the 4000 Series is its advanced security capabilities. Integrated security features help protect the network from threats while ensuring compliance with various regulatory requirements. Cisco's security technology includes built-in firewall capabilities, intrusion prevention systems (IPS), and encrypted traffic analysis, helping to safeguard sensitive data as it traverses the network.

The Cisco 4000 Series routers also excel in their support for virtualization technologies. With the capability to run multiple virtual machines and services concurrently, businesses can optimize resource usage and reduce hardware costs. This virtualization capability is facilitated by Cisco's Integrated Services Router (ISR) architecture, allowing for the efficient deployment of applications such as unified communications, collaboration tools, and cloud services.

In terms of performance, the 4000 Series routers are equipped with high-performance multi-core processors that provide significant throughput and low latency. This efficient processing power ensures that they can handle large amounts of data traffic, making them ideal for bandwidth-intensive applications like video conferencing and cloud computing.

Management and monitoring of Cisco 4000 Series routers are streamlined through Cisco DNA Center, which offers a centralized platform for automation, analytics, and assurance. This platform allows IT teams to automate network provisioning and monitoring, thus reducing the complexity associated with managing modern networks.

In summary, Cisco Systems 4000 Series routers represent a powerful solution for businesses seeking to modernize their network infrastructure. With features such as advanced routing and security, virtualization support, and enhanced management capabilities, these routers are designed to adapt to the evolving needs of enterprises in an increasingly digital world.
