This section describes how to connect to an SFP module. For instructions about

how to install or remove an SFP module, see the

Modules" section on page

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

"SFP Module Slots" section on page

Specifications"

for information about the LC on the SFP module.

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

Remove the rubber plugs from the module port and fiber-optic cable, and store

them for future use.

Insert one end of the fiber-optic cable into the SFP module port (see

Insert the other cable end into 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 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.
