Connecting to GBIC Module Ports Figure 2-40 Connecting to a 1000 BASE-X GBIC Port 1 Catalyst 2950 SERIES 2 Chapter 2 Installation 65296 Step 3 Step 4 Step 5 Insert the other cable end in a fiber-optic receptacle on a target device. 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 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 3, "Troubleshooting," for solutions to cabling problems. Reconfigure and restart the switch or target device if necessary. Connecting to 1000BASE-T GBIC Module Ports After installing the 1000BASE-T GBIC in the GBIC module slot, follow these steps: Caution To prevent ESD damage, follow your normal board and component handling procedures. Step 1 When connecting to servers, workstations, and routers, insert a four twisted-pair, straight-through cable in the RJ-45 connector. When connecting to switches or repeaters, insert a four twisted-pair, crossover cable (see Figure 2-41). Note When connecting to a 1000BASE-T device, be sure to use a four twisted-pair, Category 5 cable. 2-36 Catalyst 2950 Switch Hardware Installation Guide OL-6156-01

Step 3
Insert the other cable end in a fiber-optic receptacle on a target device.
Step 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 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 3,
“
Troubleshooting,
”
for
solutions to cabling problems.
Step 5
Reconfigure and restart the switch or target device if necessary.
Connecting to 1000BASE-T GBIC Module Ports
After installing the 1000BASE-T GBIC in the GBIC module slot, follow these steps:
Caution
To prevent ESD damage, follow your normal board and component handling procedures.
Step 1
When connecting to servers, workstations, and routers, insert a four twisted-pair, straight-through cable
in the RJ-45 connector. When connecting to switches or repeaters, insert a four twisted-pair, crossover
cable (see
Figure 2-41
).
Note
When connecting to a 1000BASE-T device, be sure to use a four twisted-pair, Category 5 cable.
