3Com 1000BASE-SX manual “Unqualified GBIC” Error, 6GBIC Transceiver Installation Guide

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.
