6GBIC Transceiver Installation Guide

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 3ComTechnical 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.

■Unqualified GBIC: MODDEF Value – xx

■Unqualified GBIC: Transceiver byte(s) error

Meaning For both of these messages, the value (xx) of this GBIC type is not a Module Definition 4 GBIC (Serial Identification) as defined by the Gigabit Interface Converter specification.

Corrective action Replace this transceiver with a GBIC that is qualified by 3Com.

GBIC Disable Error

If the system detects that the transceiver cannot emit the proper laser signal, it disables the port, sets the port type to disabled, displays a short description (GBIC Disable), and captures the error in the event log.

The following message appears in the event log:

Due to excessive TxFault conditions, GBIC Port xx has been disabled.

Meaning Excessive Tx Fault conditions indicate a faulty GBIC.

Corrective action Replace the transceiver. If the problem persists, contact network supplier or 3Com Technical Support. For contact information, see the Technical Support appendix in the Getting Started Guide for your system.

“Unapproved GBIC” Error

Supported transceivers are those that 3Com has specifically tested and qualified for use with 3Com GBIC systems. Pretesting at 3Com ensures proper functionality, compatibility, and regulatory compliance with the system.
