Load Sharing

The power supplies can operate in load-sharing mode; two 90A power supplies can produce up to 180A. Providing that the power consumption of the unit does not exceed 90 A, load-sharing allows one power supply to serve as a backup.

Overloading

When the installed power supply is rated for less than the required power consumption of the CoreBuilder module, the CoreBuilder will not succeed in powering up. It will attempt to power up, hit the current overload rate and turn the power supply off, going through this cycle repeatedly until the load is reduced.

The power consumption of an entire CoreBuilder 7000 family ATM switch unit is calculated by adding up the power consumption of the switching card(s) and interface cards installed in the chassis. Normally, the values for typical power consumption can be used in the calculation. Table 20 shows the typical power consumption values for the CoreBuilder 7000 family ATM switching cards and interface cards.

The modularity ensures that organizations can scale their network operations without significant downtime or the necessity of overhauling existing infrastructure. Such flexibility is vital for growing enterprises that need to adapt to variable workloads.

The 3Com 7000 also incorporates advanced Layer 3 routing capabilities. This feature enhances the efficiency of data transmission and bolsters the overall responsiveness of the network. By allowing routing functions to occur directly on the switch, it reduces latency and optimizes traffic flow, which is critical for applications requiring high availability, such as VoIP and video conferencing.

Security is another core characteristic of the 3Com 7000. It comes equipped with built-in security protocols and features such as Access Control Lists (ACLs) and VLAN support, which segregate network resources and protect sensitive data. These security measures ensure that only authorized devices can access specific segments of the network, thus fortifying the organization's information security posture.

In terms of management, the 3Com 7000 offers an intuitive interface for monitoring and controlling network operations. It supports various management protocols and software, which facilitate streamlined administration and configuration. This ease of management can significantly reduce the operational burden on IT staff, allowing them to focus on strategic initiatives.

Additionally, the 3Com 7000 is designed for high performance. It supports extensive bandwidth and low-latency communications, making it ideal for high-demand applications. The ability to handle multiple simultaneous connections without compromising speed makes it an excellent choice for enterprises that rely on real-time data processing.

In summary, the 3Com 7000 is a sophisticated networking solution characterized by its modularity, advanced routing capabilities, robust security features, user-friendly management, and high performance. These attributes make it a compelling choice for enterprises looking to enhance their networking infrastructure for a competitive edge.
