62-PORT 1000BASE-SXAND 2-PORT 1000BASE-LX GIGABIT ETHERNET INTERFACE MODULES QUICK START GUIDE

Order of Installation 3Com recommends that you install CoreBuilder 9000 modules in the Activities following order:

1Management Modules

One Enterprise Management Engine (EME) is required (order number 3CB9EME). A second EME or an Enterprise Management Controller (EMC) is optional (order number 3CB9EMC). By installing the management modules first, you can complete the required system-level setup procedures before you add other modules to the chassis. For more information, see the following documents:

■Enterprise Management Engine User Guide

■Enterprise Management Engine Quick Start Guide

■Enterprise Management Controller Quick Start Guide

2Switch Fabric Modules

Because you manage a GEN Interface Module through the primary GEN Switch Fabric Module, you must install one GEN Switch Fabric Module first. In the 16-slot chassis, a second GEN Switch Fabric Module is optional. See the Gigabit Ethernet Switch Fabric Module Quick Start Guide for more information.

3Interface Modules

Install all interface modules, such as the 2-port1000BASE-SXGEN Interface Module, the 2-port 1000BASE-LX GEN Interface Module, or the 36-port 10/100BASE-TX Fast Ethernet RJ-45 Layer 2 Switching Module, last. You can install interface modules in any order, but see your module documentation for chassis slot restrictions and recommendations. For restrictions and recommendations for the GEN Interface Modules, see “Module Placement in the Chassis” next in this guide.

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.
