purchase or until April 1, 2000, whichever is later.

OBTAINING WARRANTY SERVICE

Customer must contact a 3Com Corporate Service Center or an Authorized 3Com Service Center within the applicable warranty period to obtain warranty service authorization. Dated proof of purchase from 3Com or its authorized reseller may be required. Products returned to 3Com’s Corporate Service Center must be preauthorized by 3Com with a Return Material Authorization (RMA) number or User Service Order (USO) number marked on the outside of the package, and sent prepaid and packaged appropriately for safe shipment, and it is recommended that they be insured or sent by a method that provides for tracking of the package. Responsibility for loss or damage does not transfer to 3Com until the returned item is received by 3Com. The repaired or replaced item will be shipped to Customer, at 3Com’s expense, not later than thirty (30) days after 3Com receives the defective product.

3Com shall not be responsible for any software, firmware, information, or memory data of Customer contained in, stored on, or integrated with any products returned to 3Com for repair, whether under warranty or not.

Dead- or Defective-on-Arrival. In the event a product completely fails to function or exhibits a defect in materials or workmanship within the first forty-eight (48) hours of installation but no later than thirty (30) days after the date of purchase, and this is verified by 3Com, it will be considered dead- or defective-on-arrival (DOA) and a replacement shall be provided by advance replacement. The replacement product will normally be shipped not later than three (3) business days after 3Com’s verification of the DOA product, but may be delayed due to export or import procedures. The shipment of advance replacement products is subject to local legal requirements and may not be available in all locations. When an advance replacement is provided and Customer fails to return the original product to 3Com within fifteen (15) days after shipment of the replacement, 3Com will charge Customer for the replacement product, at list price.

100BASE-FX, 10/100BASE-TX specifications

3Com 10/100BASE-TX and 100BASE-FX are network technologies that played a pivotal role in the evolution of Ethernet networking. As part of the Fast Ethernet standard, these protocols allow for the transfer of data at high speeds, which has benefited various industries and residential environments.

10/100BASE-TX, often referred to simply as Fast Ethernet over twisted pair, can operate at both 10 Mbps and 100 Mbps speeds, providing flexibility for network installations. This dual-speed feature is facilitated through the use of Category 5 or higher twisted pair cabling. With the ability to automatically negotiate the optimal speed, 10/100BASE-TX allows devices to communicate effectively in diverse network environments, minimizing compatibility issues.

One of the standout characteristics of 10/100BASE-TX is its ease of installation. The use of twisted pair wiring—the same type often used for telephone lines—reduces complexity and lowers infrastructure costs. This technology also supports the use of various physical layer standards, making it adaptable for different network architectures. Power over Ethernet (PoE) capabilities are an added advantage, allowing both data and electrical power to be delivered via the same cabling, simplifying setups for devices like IP cameras and wireless access points.

On the other hand, 100BASE-FX represents Fast Ethernet over fiber optics, providing a different solution for high-speed networking. Operating at 100 Mbps, it is particularly suited for long-distance data transmission, capable of distances up to 2 kilometers using multimode fiber and up to 20 kilometers with single-mode fiber. This makes 100BASE-FX an ideal choice for interconnecting different buildings within a campus or for connecting remote offices.

In terms of technology, 100BASE-FX utilizes light waves to transmit data, resulting in lower attenuation and immunity to electromagnetic interference, a major advantage in environments with substantial electrical noise. This optical technology enhances security as fiber optics are inherently more difficult to tap into without detection.

Overall, both 3Com's 10/100BASE-TX and 100BASE-FX are significant in their contributions to networking technology. They offer unique features that cater to distinct networking needs, whether for short-range, flexible deployments using copper cabling or for long-distance, high-capacity deployments using fiber optics. Their continued relevance speaks to their robust design, versatility, and reliability in a rapidly evolving technological landscape.
