6GBIC Transceiver Installation Guide

If the transceiver is not working properly, the system displays an appropriate error message, as described in the following sections.

“Unqualified GBIC” Error

If the system detects an unqualified GBIC or a problem with the integrity of the GBIC, it sets the port type to Unqualified GBIC, displays a short description (Uqual.GBIC), and captures the error in the event log.

WARNING

The GBIC in Port xx is NOT approved by 3Com & may violate electromagnetic emission or safety requirements for your country. Refer to 3Com's web page (www.3com.com/gigabit_ethernet/gbics) for our current approved list.

Using a newer version GBIC transceiver (GBIC91, GBIC92, or GBIC97) in a system running older code (pre-Release 3.0) can generate the above message. For a list of GBIC devices that are qualified for the CoreBuilder 3500, 9000, and 9400, see this 3Com Web site:

The event log may show one of the following informational messages:

Unqualified GBIC: I2C read error

Meaning The transceiver, which connects to the module host board through a 20-pin connector is not seated properly, and a clean connection cannot be established.

Corrective action To correct this problem, completely remove the transceiver and then reinsert it. If the problem persists, contact 3Com Technical Support. For contact information in the United States and Canada, call

1-800-NET-3COM. For the number to call in other locations, visit the 3Com Web site: http://www.3com.com/util/enterprise.html.

Unqualified GBIC: Checksum match error

Meaning The system uses checksum error detection to verify the integrity of the GBIC data. If the system detects a problem with the data, it displays an error message that indicates a checksum failure.

Corrective action Although this condition does not necessarily indicate that the GBIC transceiver will not function in the system, replace the transceiver to ensure proper operation.

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.
