Introduction 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.
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/products/ At this web site, you can also find the most up-to-date information, User Guides and Release Notes about this and other 3Com products.
Direct connection to single-mode fiber-optic cable. Connection to multimode fiber through a conditioned launch cable To ensure optimal performance, compatibility, and regulatory compliance, use only conditioned launch cables that 3Com supports. For a list of currently supported conditioned launch cables, see this 3Com Web site: http://www.3Com.com/gigabit_ethernet/gbics...

Installing the Transceiver The following instructions, warnings and notes apply to all of the transceivers covered in this Guide. 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: WARNING: When the system is on: Never insert a metal object such as a screwdriver or a finger with...
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.
GBIC port. 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: http://www.3com.com/gigabit_ethernet/gbics CAUTION: GBIC transceivers are keyed and can be properly inserted only one way.
Removing the Transceiver To replace an existing GBIC transceiver, compress the side tabs and gently pull the transceiver out of the port. Figure 2 Inserting the GBIC Transceiver in a GBIC Port GBIC Port GBIC Transceiver Figure 2 shows a switch in the SuperStack 3 Switch 4900 Series. Your unit may have its GBIC port located in a different position, but the install procedure is the same.
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: http://www.3com.com/gigabit_ethernet/gbics...

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.
Safety Information You must read the following safety information before carrying out any installation or removal of components, or any maintenance procedures on the Switch. WARNING: Warnings contain directions that you must follow for your personal safety. Follow all directions carefully. You must read the following safety information carefully before you install or remove the unit.
Never look at the transmit laser while it is powered-up. Never look directly at the fiber ports and fiber cable ends when they are powered- WARNING: Use of controls or adjustments of performance or procedures other than those specified herein may result in hazardous laser emissions.
Ne regardez jamais le laser tant qu'il est sous tension. Ne regardez jamais directement le port à fibres optiques et les embouts de câbles à fibres optiques tant qu'ils sont sous tension. AVERTISSEMENT: L'utilisation de contrôles, de réglages de performances ou de procédures autres que ceux qui sont spécifiés au sein du présent document risquent d'entraîner l'exposition à...
