To connect twisted pair segments to the G‐Series switch, refer to Figure 2‐5 on page 2‐17 and connect the twisted pair segment to the switch by inserting the RJ45 connector on the twisted pair segment into the desired RJ45 port. Repeat for each connection.

Installing Optional SFP/XFP

Note: Each combo SFP port in use on the G3G124-24 or G3G124-24P base systems or the G3G-24TX module eliminates the availability of one RJ45 port. In other words, only 24 ports can be active at any given time on components equipped with a combination of RJ45 and SFP interfaces.

When an SFP transceiver (Mini-GBIC) in SFP port 23 establishes a link, RJ45 port 23 is disabled. When an SFP transceiver (Mini-GBIC) in SFP port 24 establishes a link, RJ45 port 24 is disabled.

This section describes how to install either an SFP or XFP optical transceiver into the following G3 ports:

Transceiver Type	Switch or IOM	Ports
SFP	G3G124-24, G3G124-24P, or G3G-24TX	Combo ports 23 and 24
SFP	G3G170-24 or G3G-24SFP	Any port
XFP	G3K-2XFP or G3K-4XFP	Any port

It is recommended that the options be installed first in a new installation.

Warning: Fiber-optic SFP/XFPs use Class 1 lasers. Do not use optical instruments to view the laser output. The use of optical instruments to view laser output increases eye hazard. When viewing the output optical port, power must be removed from the network adapter.

Advertencia: Los SFP/XFPs de fibra optica usan lasers de clase 1. No se debe usar instrumentos opticos para ver la potencia laser. El uso de los instrumentos opticos para ver la potencia laser incrementa el riesgo a los ojos. Cuando vean el puerto de la potencia optica, la corriente debe ser removida del adaptador de la red.

Warnhinweis: SFP/XFPs mit Fiber-Optik Technologie benutzen Laser der Klasse 1. Benutzen sie keinesfalls optische Hilfsmittel, um die Funktion des Lasers zu überprüfen. Solche Hilfsmittel erhöhen die Gefahr von Sehschäden. Wenn sie den optischen Port überprüfen möchten stellen Sie sicher, dass die Komponente von der Spannungsversorgung getrennt ist.
