Chapter2 Installation

Connecting to an SFP Module

Note Refer to the release notes for the latest information about SFP modules supported by the switch.

Follow these steps to connect a fiber-optic cable to an SFP module:

Step1 Remove the rubber plugs from the module port and fiber-optic cable, and store them for future use.

Step2 Insert one end of the fiber-optic cable into the SFP module port, as shown in Figure 2-11)

Figure2-8 Connecting to an SFP Module Port

Step3 Insert the other cable end in a fiber-optic receptacle on a target device.

Step4 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 problem with the adapter installed in the target device. See Chapter3, “Troubleshooting,” for

solutions to cabling problems.

Step5 If necessary, reconfigure and restart the switch or target device.
