Chapter 1 Overview of the Router

Hardware Features

The router can accommodate four single-wide GRWICS, or two single-wide GRWICs and one double-wide GRWIC, or two double-wide GRWICs at any one time. See “Installing Grid Router WAN Interface Cards” section on page 5-9.

Memory

Cisco CGR 2010 routers contain the following types of memory:

DDR2—Stores the running configuration and routing tables, and is used for packet buffering by the network interfaces. Cisco IOS software executes from DRAM memory. Supports 1-GB on board DDR2.

Boot/NVRAM—Stores the bootstrap program (ROM monitor), the configuration register, and the startup configuration.

Flash memory—External flash memory. Stores the operating system software image. Supports two external 4 GB I-temp compact flash memory cards.

Two 1-GB USB flash memory sticks (MEMUSB-1024FT), one each in drives USB 0 and USB 1.

Power Supplies

Cisco CGR 2010 supports three PSUs (power supply units). Power supplies are field replaceable, externally accessible, and hot swappable.

The three power supply options are summarized in Table 1-3:

Power-Supply Modules

 

 

 

Model

 

Description

 

 

PWR-RGD-AC-DC

High-voltage AC or DC power supply.

 

 

PWR-RGD-LOW-DC

Low-voltage DC power supply.

 

 

PWR-RGD-AC-DC-C

High-voltage AC or DC power supply. China-specific model.

 

 

 

Note Any combination of power supplies can be inserted into the chassis. Dual power supply configurations are load sharing in redundancy mode. A single power supply is sufficient for supporting power needs to the system.

Caution Two types of power supplies are supported on the Cisco CGR 2010 router: a low-voltage DC power supply and a high-voltage DC/AC power supply. Take caution when selecting the correct input voltage for the power supply installed or damage will result. For details on connecting AC and DC power supplies, see the “Power-Supply Modules” section on page 3-8.

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.
