Cleaning the SFP Transceiver Optics

Connecting the Switch Ports

For optical SFP transceivers, before making any optical connections, observe the following guidelines:

•Always keep the protective dust plugs on the unplugged fiber-optic cable connectors and the transceiver optical bores until you are ready to make a connection.

•Always inspect and clean the LC connector end-faces just before making any connections.

•Always grasp the LC connector housing to plug or unplug a fiber-optic cable.

To inspect the optics and connect the fiber-optic cable to the SFP transceiver, follow these steps:

Step 1 Remove the dust plugs from the network interface cable LC connectors. Save the dust plugs for future use.

Step 2 Inspect and, if necessary, clean the network cable LC connector’s fiber-optic end-faces. An inspection and cleaning procedures document is available at the following url:

Step 3 Remove the dust plugs from the SFP transceiver optical bores and immediately attach the network interface cable LC connector to the SFP transceiver.

Step 4 To connect 1000BASE-T SFP transceivers to a copper network, perform the following substeps:

Caution To comply with GR-1089 intrabuilding lightning immunity requirements, you must use grounded, shielded, twisted-pair, Category 5 cabling.

a.Insert the copper network cable RJ-45 connector into the SFP transceiver connector.

Note When connecting to a 1000BASE-T-compatible server, workstation, or router, use four twisted-pair, straight-through Category 5 cabling for the SFP transceiver port. When connecting to a 1000BASE-t-compatible switch or repeater, use four twisted-pair, crossover Category 5 cables.

b.Insert the other end of the network cable into an RJ-45 port on a 1000BASE-T-compatible target device.

Step 5 Observe the port status LED:

•The LED turns green when the SFP transceiver and the target device have an established link.

•The LED turns amber while the SFP transceiver discovers the network topology and searches for loops. This process takes about 30 seconds, and then the 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 that is installed in the target device.
