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.

Advance Replacement is provided for ninety (90) days, after which time it may be available for a specified fee. 3Com will make commercially reasonable efforts to ship the replacement product not later than five (5) business days after receiving the request for advance replacement, but may be delayed due to product availability or 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, at list price. This advance replacement is different from the fee-based Advance Hardware Replacement Service, which is available as a contracted service offering.

INCLUDED SERVICES:

Telephone Support, with coverage for basic troubleshooting only, will be provided for ninety (90) days from the date of purchase, on a commercially reasonable efforts basis. Please refer to the Technical Support appendix in the Getting Started Guide for telephone numbers.

1000BASE-SX specifications

The 3Com 1000BASE-SX is a pivotal technology in the fiber-optic networking landscape, offering high-speed data transfer capabilities that cater to various networking needs. As part of the Gigabit Ethernet standards set by IEEE 802.3, 1000BASE-SX is specifically designed for short-range applications, typically within local area networks (LANs). It utilizes multimode fiber optic cables to deliver data at speeds of up to 1 Gbps, making it ideal for environments that require efficient and fast data exchange.

One of the main features of 3Com 1000BASE-SX is its reliance on multimode fiber optic cables, which allows for the transmission of light signals with multiple paths, effectively enhancing bandwidth and distance capabilities. This technology supports distance ranges of up to 550 meters on OM2 multimode fiber and up to 300 meters on OM1 fiber, making it suitable for office buildings or campuses where networking equipment is located relatively close to one another. Given its limited range, 1000BASE-SX is best utilized in scenarios where high performance is necessary without the requirements for long-distance connections.

Another significant characteristic of the 3Com 1000BASE-SX technology is its wavelength. Operating at an 850 nm wavelength, the system utilizes vertical-cavity surface-emitting lasers (VCSELs) as a light source. VCSEL technology is favored for its efficiency and ability to provide low-cost, high-density connections, which aligns with the growing demand for robust networking solutions in modern enterprise environments.

In terms of compatibility and ease of integration, 3Com 1000BASE-SX interfaces seamlessly with Ethernet standards while also supporting various switching technologies. This versatility facilitates both the upgrade of existing networks and the construction of new, high-performance network infrastructures. Furthermore, it is backward-compatible with older Ethernet standards, allowing organizations to gradually transition to Gigabit Ethernet without the need for extensive infrastructure overhauls.

Lastly, 3Com’s adherence to industry standards ensures reliability and performance consistency across devices manufactured by different vendors, promoting interoperability. With an increasing reliance on data and the necessity for faster networking solutions, the 3Com 1000BASE-SX remains a significant choice for enterprises striving for efficiency in data traffic management and enhancing their overall network capabilities. Whether for corporate offices, educational institutions, or data centers, 3Com 1000BASE-SX offers a robust solution for the challenges of modern networking complexities.
