Connecting To Sfp Modules; Connecting To Fiber-Optic Sfp Modules - Cisco WS-C2950T-48-SI Hardware Installation Manual

Connecting to SFP Modules

Observe the port status LED.
Step 3
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
solutions to cabling problems.
Reconfigure and restart the switch or target device, if necessary.
Step 4
Connecting to SFP Modules
This section describes how to connect to SFP modules. For instructions on how to connect to fiber-optic
SFP modules, see the
connect to copper 1000BASE-T SFP modules, see the
section.
For instructions about how to install or remove an SFP module, see the
Modules" section on page
See the Catalyst 2950 LRE release notes for the list of supported SFP modules.
Note

Connecting to Fiber-Optic SFP Modules

Follow these steps to connect a fiber-optic cable to an SFP module:
Do not remove the rubber plugs from the SFP module port or the rubber caps from the fiber-optic cable
Caution
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 stipulations in
the
See
SFP modules.
Remove the rubber plugs from the module port and fiber-optic cable, and store them for future use.
Step 1
Insert one end of the fiber-optic cable into the SFP module port (see
Step 2
Step 3 Insert the other cable end into a fiber-optic connector 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 the STP discovers the network topology and searches for loops. This process
takes about 30 seconds, and then the port LED turns green.
