Installing New

Cabling

Cable Labeling and Record Keeping

If you are installing new cabling, follow these guidelines:

3Com recommends that you use a cabling system plan, such as AT&T's Premises Distribution System (PDS) or the IBM Cabling System.

Determine how many CoreBuilder 7000 units are going to be supported by each wiring closet, and how many downlink connections from these CoreBuilder 7000 units are planned.

Locate wiring closets to enable connections to the different floors.

To simplify installation of the network and to aid in troubleshooting, install a telephone in each wiring closet for communication between wiring closets, work areas, and other locations.

Include all linear distances (vertical rises, etc.) in the cable plan so that all cables - from wiring closet to desk and to other wiring closets - are under their respective maximum lengths.

A reliable cable labelling and record keeping system is essential when planning any network installation. A good cable labelling system provides enough information for you to locate the opposite end of any cable. Maintaining accurate records helps you to:

relocate devices easily

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.
