110APPENDIX D: CABLING REQUIREMENTS

■make changes quickly

■isolate faults in the distribution system

Consult the cabling system plan to set up the cable labeling and record keeping system best suited to the environment. Also consider the following recommendations:

■ Identify cables by securely attaching a label to the ends of all cables.

■ Draw a floor location grid matrix using the building floor plans. For easy reference, use this grid when assigning location numbers to cables.

■ Assign a unique block of sequential numbers to the group of cables that run between each pair of wiring closets.

■ Assign a unique identification number to each distribution rack.

■ Make all work areas and wiring closets easy to identify by labeling the front panel of the CoreBuilder 7000 and other hardware and by displaying the floor location grid and cabling plan in each wiring closet.

■ Keep accurate and up-to-date cable identification records, such as

 

IBM's Cable Identification Label Sheet or Cable Schedule. Post records

 

near each distribution rack. On the appropriate cable schedule, record

 

the following cable drop information: the cable source, destination,

 

jumper location, and any additional information.

 

■ Make sure that optical and coax cables are labeled Rx and Tx

 

accordingly.

 

 

ATM Cabling

When planning the installation, thoroughly inspect the present cabling to

 

determine if it meets the specifications in the cabling system or standards

 

used at the site.

 

In addition to adhering to the local standards, all cable must conform to

 

the American National Standard ATM Physical Layer Medium Dependent

 

(PMD) standard, ISO.166-1990, American National Standards Institute,

 

which defines the Physical Medium Dependent (PMD) layer of the ATM

 

network. Currently, there are two approved PMD standards: Multi-mode

 

Fiber (MMF-PMD), which is defined in ANSI standard X.3-166-1992, and

 

Single Mode Fiber (SMF-PMD), which is defined in ANSI standard

 

x.3-184-198x.

7000 specifications

The 3Com 7000 is a robust and versatile networking solution designed to meet the demands of enterprise environments. Renowned for its reliability and scalability, the 3Com 7000 is highly suitable for organizations requiring efficient data handling and enhanced network performance. This multi-layer switching platform integrates advanced technologies, making it a preferred choice for modern businesses.

One of the standout features of the 3Com 7000 is its modular architecture. This design allows businesses to customize their network according to specific requirements by adding or replacing various modules. 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.
