Warning: Fiber optic equipment can emit laser or infrared light that can injure your eyes. Never look into an optical fiber or connector port. Always assume that fiber optic cables are connected to a light source.

Vor si ch t: Glasfaserkomponenten können Laserlicht bzw. Infrarotlicht abstrahlen, wodurch Ihre Augen geschädigt werden können. Schauen Sie niemals in einen Glasfaser-LWL oder ein Anschlußteil. Gehen Sie stets davon aus, daß das Glasfaserkabel an eine Lichtquelle angeschlossen ist.

Avertissement: L’équipement à fibre optique peut émettre des rayons laser ou infrarouges qui risquent d’entraîner des lésions oculaires. Ne jamais regarder dans le port d’un connecteur ou d’un câble à fibre optique. Toujours supposer que les câbles à fibre optique sont raccordés à une source lumineuse.

Advertencia: Los equipos de fibra óptica pueden emitir radiaciones de láser o infrarrojas que pueden dañar los ojos. No mire nunca en el interior de una fibra óptica ni de un puerto de conexión. Suponga siempre que los cables de fibra óptica están conectados a una fuente luminosa.

Avvertenza: Le apparecchiature a fibre ottiche emettono raggi laser o infrarossi che possono risultare dannosi per gli occhi. Non guardare mai direttamente le fibre ottiche o le porte di collegamento. Tenere in considerazione il fatto che i cavi a fibre ottiche sono collegati a una sorgente luminosa.

Introduction to Gigabit Interface Converters

This section describes the Gigabit Interface Converter (GBIC) and label, and provides a GBIC model list.

Product description

Gigabit Interface Converters (GBICs) are hot-swappable input/output enhancement components designed for use with Nortel Networks* link with fiber optic networks.

Note: GBIC wavelength distance may vary, depending

on the quality of fiber optic cable used.

Handling, safety, and environmental guidelines

Before installing your GBIC, read the following handling, safety, and environmental guidelines:

• GBICs are static sensitive. To prevent damage from electrostatic discharge (ESD), follow your normal board and component handling procedures.

• GBICs are dust sensitive. When you store a GBIC, or when you disconnect it from a fiber optic cable, always keep the dust cover over the GBIC’s optical bores.

• To clean contaminants from the optical bores of a GBIC, use an alcohol swab or equivalent to clean the ferrules of the optical connector.

• Dispose of this product according to all national laws and regulations.

Warning: Fiber optic equipment can emit laser or

infrared light that can injure your eyes. Never look into an optical fiber or connector port. Always assume that fiber optic cables are connected to a light source.

Installing a GBIC

This section lists the steps to install a GBIC.

To install a GBIC:

1 Remove the GBIC from its protective packaging.

2 Verify that the GBIC is the correct model for your network

configuration (Table 1 on page 4).

3 Remove the dust cover from the GBIC’s optical bores.

4 Grasp the GBIC between your thumb and forefinger.

5 Insert the GBIC into the slot on the front panel of the Gigabit

Ethernet switching module (Figure 3) .

Figure 3 Inserting the GBIC into the switching module

Note: GBICs are keyed to prevent incorrect insertion.

Removing a GBIC

This section lists the steps for removing a GBIC.

To remove a GBIC:

1 Disconnect the network fiber cable from the GBIC

connector.

2 Depending on your GBIC model, either grasp the extraction

tabs (Figure 1) located on either side of the GBIC with your thumb and forefinger, or lift the extractor handle (Figure 1) attached to the GBIC.

3 Slide the GBIC out of the Gigabit Ethernet module slot.

4 If the GBIC does not slide easily from the module slot, use a

gentle side-to-side rocking motion while firmly pulling the GBIC from the slot.

5 Dispose of the GBIC according to all national laws and

regulations.

Note: If you are storing a GBIC, remember to place a

dust cover over the fiber optic bores.
