Hot-swappable Power Supplies. You can remove and replace either of the two power supplies at the back of the chassis. Turning off one of the power supplies generates a sound, and the control panel LCD displays Input Failure. The LED of each power supply lights green when the power supply is running correctly. If the power supply fails, the system generates a sound and the power supply LED does not light.

To remove a faulty power supply and replace it with a new unit, follow these steps:

1Turn off the power supply according to the safety and removal procedures in the Installation Guide that is shipped with the new power supply. The system control panel displays the following message (where n designates power supply 1 or power supply 2):

Power Supply n: Input Failure

2Remove the power supply. The system generates a sound, and the system control panel displays the following message:

Power supply n extracted.

3Insert the new power supply, following the instructions and safety warnings in the Installation Guide that comes with the new power supply. The system displays this message:

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.
