Release Notes v2.41 • Page 18

Main application file: default name is main.bin, file type M. This is the default file the system uses to boot.

Backup application file: default name is backup.bin, file type B. This file will be used to boot system when the main file fails.

Secure application file: default name is secure.bin, file type S. This file will be used to boot the router when the main and backup file fails. The system will display a booting failure message if the secure application file also fails.

Note:

Only the application file types M, B, and S can be used to boot the system. Applications marked as N/A cannot be used to boot the router.

The names of the applications in Flash can be modified using CLI commands after the router has started. Refer to the “System Management” document for more information on the CLI commands. The application file types M, B, and N/A can be modified in either the Boot ROM menu or by the CLI commands after the application is started. Modifications to the file type of applications with type S are not allowed.

Because the secure boot file is the last file the system uses to boot properly, the file type of secure boot file is not allowed to be changed, nor is it derived from any other type of file. It can only be downloaded via the Boot ROM menu, and its name must be specified as secure.bin. If you change the file name of the secure file using rename command after the system has started, there is no secure boot file in Flash and you need to download it again.

Only one file of each type (M, B, and S) can exist in Flash. For example, if a file of type M and a file of type B exist in Flash, it is impossible to have a second file type of M or B. If the file type of another application is to be changed to B, the existing file of type B will be changed to N/A.

When you select option 3 in the Boot ROM menu, the following menu appears (suppose there are four application files stored in Flash, all of which with following types:)

The following menu appears if you select 3, through which you can change the file type of a.bin.

Set this file as:

Enter your choice(1-3): 1

If you select 1, a.bin will be specified as the main boot file. When the modification is validated, the type of the original main file is changed to N/A., and a.bin will be used to boot the router.

5000, 6000 specifications

The 3Com 6000 series, launched in the late 1990s, was a significant advancement in networking technology, designed to meet the growing demands of enterprise-level networking. This series provided powerful solutions for businesses seeking reliable, efficient, and scalable networking capabilities.

At its core, the 3Com 6000 series featured a modular design, allowing companies to customize their networks according to specific needs. This flexibility meant that organizations could add or replace components as their networking requirements evolved, ensuring investment protection and a tailored approach to connectivity. The ability to scale was particularly important for businesses that anticipated growth or change in operational demands.

One of the standout features of the 3Com 6000 was its advanced switching capabilities. The series employed high-performance switching technologies that supported various protocols, including Fast Ethernet and Gigabit Ethernet. This versatility made it suitable for diverse environments, from small offices to large corporate settings. The 3Com 6000 switches were engineered to deliver high throughput and low latency, crucial for applications requiring real-time data transfer.

The series also supported a range of network management tools, enhancing operational efficiency. With SNMP (Simple Network Management Protocol) support, network administrators could easily monitor and manage network performance, troubleshoot issues, and configure devices from a centralized location. This capability significantly streamlined network operations, reducing downtime and optimizing resource allocation.

Security was another significant concern addressed by the 3Com 6000. The series incorporated robust security features, including access control lists (ACLs) and VLAN (Virtual Local Area Network) support. These features allowed network administrators to segment traffic and enforce security policies, protecting sensitive data and ensuring compliance with organizational standards.

Moreover, the 3Com 6000 series was designed with energy efficiency in mind, reflecting a growing awareness of the environmental impact of IT infrastructure. By implementing power-saving features, the series helped organizations reduce their overall energy consumption while maintaining optimal network performance.

In summary, the 3Com 6000 series stood out for its modularity, advanced switching capabilities, extensive management tools, strong security features, and energy efficiency. It represented a forward-thinking solution for enterprises aiming to build robust network infrastructures capable of supporting a wide range of applications and services. As organizations increasingly relied on networked systems, the 3Com 6000 played a crucial role in shaping the landscape of enterprise networking.
