To avoid electric shocks and burns to yourself and damage to the equipment, read and follow these warnings: WARNINGS: When the system is on: ■ Never insert a metal object such as a screwdriver or a finger with jewelry into open module slots. ■ Do not touch any connections inside the chassis with your hands or fingers. Fiber Safety Precautions The GBIC ports on your system use lasers. To ensure your safety when you install or work with these GBIC systems, read and comply with the precautions in this section. WARNING: The fiber optic lasers used in 3Com GBIC ports meet the regulatory requirements for casual exposure to the eye. As with any source of bright light, however, 3Com recommends that you do not look into the laser light source. IEC 825, Class 1 Laser Devices are for connection only to Class 1 Laser Devices. Multimode and single-mode fiber optic interfaces use lasers. CLASS 1 LASER PRODUCT 4 GBIC Transceiver Installation Guide Inserting the Transceiver Before you connect the system to the Gigabit Ethernet network, first insert the transceiver into the GBIC port on the system, as described in this section. The procedure is similar for all relevant chassis. To ensure optimal performance, compatibility, and regulatory compliance, use only GBIC transceivers that 3Com supports. For a list of GBIC devices that are qualified for the CoreBuilder® 3500, 9000, and 9400, see this 3Com Web site: http://www.3com.com/gigabit_ethernet/gbics 1 Read and follow the instructions in “Safety Precautions” earlier in this guide. 2 Orient the transceiver so that the duplex SC connector is toward you. CAUTION: GBIC transceivers are keyed and can be properly inserted only one way. If the transceiver does not click when you insert it, remove it, turn it over, and reinsert it. a Figure 2 shows how to insert the transceiver into a CoreBuilder 3500 GBIC port.

CAUTION: GBICs are keyed and can be inserted only one way. If the GBIC does not click when you insert it, remove the GBIC, turn it over, and reinsert it. Removing the Transceiver To replace an existing GBIC transceiver, compress the side tabs and gently pull the transceiver out of the port. Troubleshooting Transceivers After you insert the GBIC transceiver into the port, the system software verifies the transceiver operation, as discussed in this section. To ensure optimal performance, compatibility, and regulatory compliance, use only GBIC transceivers that 3Com supports. For a list of currently supported GBICs, see this 3Com Web site: http://www.3com.com/gigabit_ethernet/gbics 6 GBIC 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: http://www.3com.com/gigabit_ethernet/gbics 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. ■ Meaning Corrective action Unqualified GBIC: Checksum match error 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. Although this condition does not necessarily indicate that the GBIC transceiver will not function in the system, replace the transceiver to ensure proper operation. GBIC Transceiver Installation Guide Meaning Corrective action ■ Unqualified GBIC: MODDEF Value – xx ■ Unqualified GBIC: Transceiver byte(s) error 7 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. 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 Corrective action Excessive Tx Fault conditions indicate a faulty GBIC. 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. If the system detects a transceiver that 3Com does not support, it sets the port type to Unqualified GBIC, displays a short description, (Unappr.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. The following informational message is shown in the event log: Unqualified GBIC: Unqualified vendor part number Corrective action Although this report does not necessarily indicate that the GBIC transceiver will not function properly with the system, it does indicate that 3Com has not qualified the transceiver and does not support it. 8 GBIC Transceiver Installation Guide Incorrect Value in the Ethernet Display Field (CoreBuilder 3500) An incorrect value appears in the Ethernet display field when all of these conditions are true: ■ Your CoreBuilder 3500 is running system software at Release 2.1 or earlier. ■ You have installed or reinstalled a new or replacement GBIC (for example, Model Number 3CGBIC91, 3CGBIC92 or 3CGBIC97). ■ You enter the ethernet summary or the ethernet detail command for the first time. When all of these conditions are true, the text (GBIC) Non-qualified appears in the portType field of the Ethernet display even though the GBIC is qualified and functions properly. Disregard this incorrect value. 3Com Corporation LIMITED WARRANTY 3Com GBIC Transceivers HARDWARE 3Com warrants to the end user (“Customer”) that this hardware product will be free from defects in workmanship and materials, under normal use and service, for one (1) year from the date of purchase from 3Com or its authorized reseller. 3Com’s sole obligation under this express warranty shall be, at 3Com’s option and expense, to repair the defective product or part, deliver to Customer an equivalent product or part to replace the defective item, or if neither of the two foregoing options is reasonably available, 3Com may, in its sole discretion, refund to Customer the purchase price paid for the defective product.
