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.
Vorsicht: 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 fi bre ottiche o le porte di collegamento. Tenere in
considerazione il fatto ch e i cavi a fibre ottic he son o coll eg at i a una
sorgente luminosa.

Handling, safety, and environmental
guidelines
Before installing yo ur GBIC, read the following hand ling, safety,
and environmental gui del ines:
• GBICs are static sensitive . To prevent damage from
electrostatic di scharge (ESD), follow your normal board
and component handl ing procedur es.
• GBICs are dust sensitive. When you store a GBIC, or when
you disconnect it from a fiber optic cable, alway s keep the
dust co ver over the GBI C ’s optical bores.
• To clean contaminants from the op tical bores of a GBIC,
use an alcohol swab or equivalen t 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 ligh t tha t can inju re you r eyes. Ne ver l ook into
an optical fiber or co nnector port. Always assume that
fiber optic cables are connecte d 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.
5
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 th umb and forefinger.
5 Insert the GBIC into th e slot o n the fro nt pa nel of th e Gigab it
Ethernet switching module (Figure 3) .
Figure 3 Insert in g th e G BI C into th e sw i t ching modul e
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.
6
2 Depending on your GBIC model, either grasp the extraction
tabs (Figure 1) located on either side of the GBIC with your
thumb and f orefinger, 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 roc king mo tio n whil e firmly pu llin g 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.

Note: When shorter le ngths of single-mode fiber cable
are used, th ere i s a risk of overloading t he receiver. It
may be necessary to insert an in-line optical attenuator
in the link to prevent overloading, as follows:
• Insert a 10 dB in-line optical attenuator between the
fiber optic ca ble plant and the re ceiving port on the
1000BA SE-ZX GBIC, at each end of the li nk , if the
fiber optic ca ble span is less than 25 km.
• Insert a 5 dB in line o pt ical attenuator between the
fiber optic ca ble plant and the re ceiving port on the
1000BA SE-ZX GBIC, at each end of the li nk , if the
fiber optic ca ble span is less than 50 km.
