Installation of Fiber Optic Transceiver Module

Necessary tools: ESD-preventive wrist strap

Take the SFP module as an example.

Complete these steps in order to install a SFP transceiver:

1. Attach an ESD-preventive wrist strap to your wrist and to the ESD ground connector or a bare metal surface on your chassis.
2. Remove the SFP Transceiver Module from its protective packaging.
3. Check the label on the SFP transceiver body to verify that you have the correct model for your network.
4. Find the send (TX) and receive (RX) markings that identify the top side of the SFP transceiver.
5. Position the SFP transceiver in front of the socket opening.
6. Insert the SFP transceiver into the socket until you feel the SFP Transceiver Module connector snap into place in the socket connector.
7. Remove the dust plugs from the network interface cable LC connectors. Save the dust plugs for future use.
8. Remove the dust plugs from the SFP transceiver optical bores.
9. Immediately attach the network interface cable LC connector to the SFP transceiver.
10. Connect the 1000BASE-T SFP transceivers to a copper network.
11. 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 STP 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 installed in the target device. Refer to the Troubleshooting section of your switch hardware guide for solutions to cabling problems.
• Reconfigure and reboot the target device if necessary.

Installation Note:

1. Do not remove the optical bore dust plugs until directed to do so later in the procedure.
2. On some SFP transceivers, the TX and RX marking might be replaced by arrowheads that point from the SFP transceiver connector (transmit direction or TX) and toward the connector (receive direction or RX).
3. Different devices have different SFP module socket configurations. Your device could have either a latch-up or a latch-down orientation. Ensure that you are installing the SFP transceiver in the correct orientation for your device. Refer to the hardware installation instructions that came with your device for more details.
4. For optical SFP transceivers, before you remove the dust plugs and make any optical connections, observe these guidelines:

1. 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.
2. Always inspect and clean the LC connector end-faces just before you make any connections. See the Required Tools section of this document for more information.
3. Always grasp the LC connector housing to plug or unplug a fiber-optic cable.

Caution:

In order to comply with GR-1089 intra-building lightning immunity requirements, you must use grounded, shielded, twisted-pair Category 5 cabling.

Complete these steps in order to connect the transceivers to a copper network:

1. Insert the Category 5 network cable RJ-45 connector into the SFP transceiver RJ-45 connector.

When you connect to a 1000BASE-T-compatible server, work station, or router, use four twisted-pair, straight-through Category 5 cabling for the SFP transceiver port. When you connect to a 1000BASE-T compatible switch or repeater, please use four twisted-pair, crossover Category 5 cabling.

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