Chapter 4 Configuring the Gigabit Ethernet Ports Figure 4-7 Connecting to an SFP Module Port Connecting To an SFP Module 98656 Step 3 Step 4 Insert the other cable end in a fiber-optic receptacle on a target device. Observe the port 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 Chapter 5, "Troubleshooting the Installation," for solutions to cabling problems. 78-6286-05 Catalyst 2984G, 2948G-GE-TX, and 2980G Switch Hardware Installation Guide 4-15
