Making Network Connections
Nota:
Cuando seleccione un dispositivo SFP de fibra óptica, y teniendo en cuenta la
seguridad, asegúrese de que el mismo pueda operar a una temperatura que no
sea mayor que la temperatura máxima recomendada de operación del producto.
Se deberá asimismo utilizar un transceptor SFP láser clase 1 aprobado.
1.
Remove and keep the LC port's rubber cover. When not connected to a fiber
cable, the rubber cover should be replaced to protect the optics.
2.
Check that the fiber terminators are clean. You can clean the cable plugs by
wiping them gently with a clean tissue or cotton ball moistened with a little
ethanol. Dirty fiber terminators on fiber cables will impair the quality of the light
transmitted through the cable and lead to degraded performance on the port.
3.
Connect one end of the cable to the LC port on the switch and the other end to
the LC port on the other device. Since LC connectors are keyed, the cable can
be attached in only one orientation.
4.
As a connection is made, check the Link LED on the switch corresponding to
the port to be sure that the connection is valid.
The 1000BASE-SX, 1000BASE-LX and 1000BASE-ZX fiber optic ports operate at
1 Gbps full duplex. The maximum length for fiber optic cable operating at Gigabit
speed will depend on the fiber type as listed under "1000 Mbps Gigabit Ethernet
Collision Domain" on page 4-5.
Connectivity Rules
When adding hubs (repeaters) to your network, please follow the connectivity rules
listed in the manuals for these products. However, note that because switches break
up the path for connected devices into separate collision domains, you should not
include the switch or connected cabling in your calculations for cascade length
involving other devices.
