Chapter 2 Preparing for Router Installation

Network Cabling Specifications

The default parameters for the console port are 9600 baud, 8 data bits, no parity, and 1 stop bit. The console port does not support hardware flow control. For detailed information about installing a console terminal, see the “Connecting to a Console Terminal or Modem” section on page 3-17.

For cable and port pinouts, see Cisco Modular Access Router Cable Specifications.

USB Serial Console Port

The USB serial console port connects directly to the USB connector of a PC using a USB Type A to 5-pin mini USB Type-B cable. The USB Console supports full speed (12Mb/s) operation. The console port does not support hardware flow control.

Note Always use shielded USB cables with a properly terminated shield.

The default parameters for the console port are 9600 baud, 8 data bits, no parity, and 1 stop bit. The console port does not support mode control. For detailed information about installing a console terminal, see the “Connecting to a Console Terminal or Modem” section on page 3-17.

For operation with Microsoft Windows, the Cisco Windows USB Console Driver must be installed on every PC connected to the console port. If the driver is not installed, prompts guide you through a simple installation process. For detailed information about installing the Cisco Windows USB Console Driver see “Installing the Cisco Microsoft Windows USB Device Driver” section on page 3-21.

The Cisco Windows USB Console Driver allows plugging and unplugging the USB cable from the console port without affecting Windows HyperTerminal operations. No special drivers are needed for Mac OS X or Linux.

Only one console port can be active at a time. When a cable is plugged into the USB console port the RJ-45 port becomes inactive. Conversely, when the USB cable is removed from the USB port, the RJ-45 port becomes active.

Baud rates for the USB console port are 1200, 2400, 4800, 9600, 19200, 38400, 57600, and 115200 bps.

Note 4-pin mini USB Type-B connectors are easily confused with 5-pin mini USB Type-B connectors. They are not compatible. Only the 5-pin mini USB Type-B can be used.

Auxiliary Port Connections

The router has an EIA/TIA-232 asynchronous serial auxiliary port (RJ-45) that supports flow control. Depending on the cable and the adapter used, this port appears as a DTE or DCE device at the end of the cable.

Preparing for Network Connections

When setting up your router, consider distance limitations and potential electromagnetic interference (EMI) as defined by the applicable local and international regulations.

Network connection considerations are provided for several types of network interfaces and are described in the following sections:

OL-31454-01 specifications

Cisco Systems OL-31454-01 refers to a specific configuration guide for Cisco networking equipment, which serves an essential role in helping IT professionals understand how to deploy and manage their networking hardware efficiently. This document is particularly relevant for those working with Cisco routers and switches, highlighting various features, technologies, and best practices in network management.

A core feature of Cisco Systems OL-31454-01 is its focus on enhancing network performance and reliability. The systems typically include advanced Quality of Service (QoS) mechanisms, ensuring that critical applications receive the necessary bandwidth and performance even during peak usage times. This is crucial for enterprises that rely on uninterrupted access to applications and services.

The guide also discusses technologies such as VLANs (Virtual Local Area Networks), which allow network administrators to segment networks for improved performance and security. By isolating traffic within different VLANs, organizations can mitigate congestion and enhance overall network efficiency.

Another critical aspect of OL-31454-01 is its in-depth look at security features. Cisco networking solutions typically come equipped with integrated security protocols, such as IPsec for Virtual Private Networks (VPNs) and advanced threat detection mechanisms. This layered approach to security helps protect sensitive data from unauthorized access and cyber threats.

Furthermore, the guide emphasizes the importance of automation and programmability in modern networks. Utilizing Cisco's software-defined networking (SDN) capabilities, network engineers can automate various tasks, reducing the potential for human error and freeing up valuable resources. The integration of tools like Cisco DNA Center provides a unified network management platform, enhancing visibility and control across the entire network.

In addition to these features, Cisco Systems OL-31454-01 outlines various compatibility options with existing technologies and infrastructure. The guide ensures that IT teams can seamlessly integrate new hardware into their current networks without significant overhauls, facilitating a more efficient transition.

Overall, OL-31454-01 serves as a comprehensive resource for deploying and managing Cisco systems, offering valuable insights into essential features, technologies, and best practices that can significantly enhance an organization's networking capabilities.
