Chapter 3 Installation
Connecting to an SFP Module
Step 2
Insert the other cable end in a port on a target device.
Step 3
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 a problem with the adapter installed in the target
device. See
Chapter 4, “Troubleshooting,”
for solutions to cabling problems.
Step 4
Reconfigure and restart the switch or target device, if necessary.
Connecting to an SFP Module
This section describes how to connect to an SFP module. For instructions about
how to install or remove an SFP module, see the
“Installing and Removing SFP
Modules” section on page 3-28
.
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 an SFP module, be sure that you understand the port and
cabling stipulations in
Table 2-2 on page 2-16
and in the
“SFP Module Slots”
section on page 2-14
. See
Appendix B, “Connectors and Cables,”
for information
about the LC on the SFP module.
Note
Refer to the Catalyst 2950 LRE release notes for the list of supported SFP
modules.
