GBIC Transceiver  
Installation Guide  
For 3Com Gigabit Interface Converter (GBIC) Transceivers  
Description The Gigabit Interface Converter (GBIC) ports on your system connect to  
Gigabit Ethernet networks through a GBIC transceiver (Figure 1),  
providing a high-speed connection over fiber-optic or copper cable. The  
transceiver connects to the network using a fiber-optic duplex subscriber  
connector (SC) or a RJ-45 connector. You can remove and replace the  
transceiver with the system on (which is called hot-swapping).  
Figure 1 GBIC Fiber-Optic Transceiver  
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:

Safety Precautions Be sure to follow all safety precautions when you replace a GBIC  
transceiver in the system. 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 fiber 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.

GBIC Transceiver Installation Guide  
Inserting the Before you connect the system to the Gigabit Ethernet network, first  
Transceiver insert the transceiver into the GBIC port on the system, as described in  
this section. The procedure is similar for all relevant chassis or modules.  
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 3Com products see this 3Com Web site:  
1 Read and follow the instructions in “Safety Precautions” earlier in this  
guide.  
2 Orient the transceiver so that the duplex SC or RJ-45 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 GBIC port.  
Installation into other chassis is the same except that the chassis ports  
may be oriented vertically.

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 After you insert the GBIC transceiver into the port, the system software  
Transceivers verifies the transceiver operation. If you should experience problems refer  
to the steps and conditions below.  
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:  
No LED Error  
Corrective action If the GBIC LED does not light after you insert it into the chassis, remove  
the GBIC and re-insert it.  
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  
Using a newer version GBIC transceiver (GBIC91, GBIC92, GBIC93, 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  
Switch 4007, see this 3Com Web site:  
The event log may show one of the following informational messages:  
Unqualified GBIC: I2C read error  
 
6
GBIC 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  
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.  
 
GBIC Transceiver Installation Guide  
7
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  
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.
