Connecting to SFP Modules
This section describes how to connect to a fiber-optic SFP port. For instructions on how to install or remove an SFP
module, see
Installing and Removing SFP Modules, page
Warning:
Class 1 laser product. Statement 1008
Warning:
Do not connect or disconnect cables to the ports while power is applied to the switch or any device on
the network because an electrical arc can occur. This could cause an explosion in hazardous location installations.
Be sure that power is removed from the switch and cannot be accidentally be turned on, or verify that the area is
nonhazardous before proceeding. Statement 1070
Caution:
Do not remove the rubber plugs from the SFP module port or the rubber caps from the fiber-optic cable
until you are ready to connect the cable. The plugs and caps protect the SFP module ports and cables from
contamination and ambient light.
Before connecting to the SFP module, be sure that you understand the port and cabling guidelines in the
for Installation, page
To connect a fiber-optic cable to an SFP module, follow these steps:
1.
Remove the rubber plugs from the module port and fiber-optic cable, and store them for future use.
2.
Insert one end of the fiber-optic cable into the SFP module port.
3.
Insert the other cable end into a fiber-optic receptacle on a target device.
4.
Observe the port status LED:
—
The LED turns green when the switch and the target device have an established link.
—
The LED turns amber while the STP discovers the network topology and searches for loops. This process takes
about 30 seconds, and then the port LED turns green.
—
If the LED is off, the target device might not be turned on, there might be a cable problem, or there might be a
problem with the adapter installed in the target device. See
problems.
5.
If necessary, reconfigure and restart the switch or the target device.
Where to Go Next
If the default configuration is satisfactory, the switch does not need further configuration. You can use any of these
management options to change the default configuration:
Start Device Manager, which is in the switch memory, to manage individual and standalone switches. This is an
easy-to-use web interface that offers quick configuration and monitoring. You can access Device Manager from
anywhere in your network through a web browser. For more information, see the Express Setup section of the Device
Manager online help.
