1.The C7200-I/O-GE+E and C7200-I/O-2FE/E do not have a boot ROM component.

2.Some I/O controllers have no Flash SIMM but use a permanently soldered 4-MB or 8-MB flash memory chip instead. (For the location of the 4-MB Flash memory chip, see Figure 1-18and Figure 1-20. For the location of the 8-MB flash memory chip, see Figure 1-15and Figure 1-16.)

3.The NVRAM on some I/O controllers is replaced by a 32-pin nonsocketed SRAM component that is soldered onto the card. The SRAM component is made to act like the NVRAM by the addition of some external components, one of which is a 1-inch (2.54-cm) button-type lithium battery.

LED Descriptions

All I/O controllers have LEDs, and the NPE-G1 and NPE-G2 also have interfaces that have LEDs.

The I/O controller faceplate contains LEDs that indicate system and port status; two additional LEDs indicate the status of the Flash Disk or flash memory cards installed in either PC Card slot. A CPU reset button is located next to the IO POWER OK LED or next to the auxiliary port on the I/O controller faceplate. The CPU reset button resets the entire system.

The NPE-G2 and NPE-G1 faceplate contains LEDs that indicate system and port status. The RJ-45 and GBIC or SFP ports share the same LINK LED because only one of these ports per interface (0/1, 0/2, or 0/3) can be used at any one time. The ENABLE LED is on if the RJ-45 port is in use. The POWER ON LED on the NPE-G1 or the PWR OK LED on the NPE-G2 is on when the system is powered on, whether

7200 VXR specifications

The Cisco Systems 7200 VXR Series is a robust and highly scalable modular router designed to meet the demands of service providers and enterprises seeking high-performance solutions for their network infrastructures. Launched as part of the Cisco 7200 series, the VXR (Virtual Extensible Routing) variant enhances capabilities while providing effective support for a wide range of applications, including Internet Protocol (IP) routing, Voice over IP (VoIP), and Virtual Private Network (VPN) configurations.

At the core of the 7200 VXR is its modular design, which enables network administrators to customize the router according to their specific needs. The router supports a variety of interface cards, processing engines, and power supply options, ensuring flexibility for diverse network environments. This modularity facilitates easy upgrades and expansions, making it ideal for growing enterprises and service providers looking to future-proof their networks.

One of the standout features of the Cisco 7200 VXR is its impressive routing performance. It can handle a high level of traffic with low latency, which is critical for bandwidth-intensive applications. The router supports a wide array of routing protocols, including Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), and Integrated Intermediate System-to-Intermediate System (IS-IS), providing versatility for various network topologies.

The 7200 VXR also incorporates advanced features for enhanced security and reliability. With support for IPsec VPNs, it enables secure data transmission across untrusted networks. The router also includes features like Quality of Service (QoS) for prioritizing network traffic, ensuring critical applications receive the bandwidth they require even during peak loads.

In terms of scalability, the Cisco 7200 VXR can support hundreds of thousands of routes and MAC addresses, making it suitable for large metropolitan area networks (MANs) as well as enterprise backbone applications. It also provides the capability to support IPv4 and IPv6 networks, preparing organizations for a transition to next-generation internet protocols.

Additional characteristics of the Cisco 7200 VXR include enhanced manageability through the Cisco IOS software, which offers a comprehensive command-line interface and support for network management protocols. The router is also energy-efficient, with options for redundant power supplies that ensure continuous availability and minimal downtime in mission-critical applications.

Overall, the Cisco Systems 7200 VXR represents a powerful solution that combines performance, scalability, and security, making it an excellent choice for organizations looking to enhance their network capabilities in a rapidly evolving technological landscape.
