Installing an SFP-DD transceiver

About this task

SFP double density (SFP-DD) transceivers are delivered with two dust caps. When inserting cables, remove one dust cap and insert the cable, leaving the other dust cap in place. Then remove the other dust cap and insert the next cable. If you are using only one cable in the transceiver, keep the other dust cap in place to keep the transceiver clean. Consider the following when installing these transceivers and cables: Consider the following when installing these transceivers:

Always use the pull tab to insert or remove a transceiver, because the SFP-DD might be hot.
You might find it easier to insert the cables into the transceiver first and then install the transceiver.

Procedure

Use the pull tab on the SFP-DD transceiver to help push the transceiver into the port. Transceivers are keyed so that they can be inserted only with the correct orientation. If a transceiver does not slide in easily, ensure that it is correctly oriented. Push the correctly oriented transceiver into the port until it is firmly seated and the latching mechanism clicks.

For the top row of ports, insert the transceiver so that the pull tab is on the bottom. For the bottom row of ports, insert the transceiver so that the pull tab is on the top.

Figure 1. Installing SFP-DD transceivers
Remove the first dust cap from the transceiver. Leave the second dust cap in place.
Position a cable so that the molded grid pattern and wide key tab on one side of the cable connector are facing up (away from the transceiver pull tab).

Note: Hold the white push-pull boot, and push the connector straight into the port.

Figure 2. Orientation of the SFP-DD connector
Hold the white push-pull boot, and push the connector straight into the port on the transceiver until the latching mechanism clicks. The connector will make two soft clicks as it enters the port, and the wide key will fit into the key slot on the SFP-DD transceiver.

For the lower row of ports, position the connector so that the molded grid pattern is facing down (away from the pull tab).

Note: Cables are keyed so that they can be inserted in only one way. If a cable does not slide in easily, ensure that it is correctly oriented. Do not force the cable. Do not insert any unsupported cable or a cable that is intended for another type of transceiver into an SFP-DD transceiver. You may damage the cable as well as the transceiver.
Gently tug on the cable to make sure that it is seated firmly.
