5:Exit to Main Menu Enter your choice(1-5):

10Ignore software check (Boot Menu option a).

When upgrading software, make sure that you are using the correct software version. If the upgrade still fails and the system displays “invalid version” in this case, you can use this option. It allows the system to upgrade software without checking the version of extended Boot ROM image segment, Boot ROM image, and application image for backward compatibility. This is a one-time operation, however; the router checks version again at reboot.

11Boot from Flash (Boot Menu option b).

12Boot from the CF card (Boot Menu option c).

13Exit and reboot (Boot Menu option d).

Upgrading Software You can use the console port to upgrade software using Xmodem Using Xmodem without the need of setting up a configuration environment.

Upgrading the application image

1From the Boot Menu (refer to the section “Boot Menu”) and enter option 1 to download an application image using Xmodem. The router supports the following downloading speeds:

Please choose your download speed:

1:9600 bps

2:19200 bps

3:38400 bps

4:57600 bps

5:115200 bps

6:Exit to Main Menu

Enter your choice(1-6):

2Select an option. For example, if option 5 for 115200 bps is selected, the following message appears:

Download speed is 115200 bps. Change the terminal’s speed to 115200 bps, and select XModem protocol. Press ENTER key when ready.

3Change the terminal baud rate (see Figure 21) to the same baud rate for software download (115200 bps in this example). After that, select [Dial-in/Disconnect] to disconnect the terminal, and [Dial-in/Dialing] to reconnect it. Then, press <Enter> to start downloading. The system displays:

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.
