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.
About this task
Consider the following when installing these transceivers and cables:
Note:
Always use the pull tab to insert or remove a transceiver, because the transceiver 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.
Insert the transceiver so that the pull tab is on the bottom.

3. Pull Tab of transceiver in upper row
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).
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.
Note: This photo is for illustration/instructional purposes
only. This graphic displays two rows of SFP-DD ports and is used to illustrate installing an SFP-DD
transceiver. However, SAN42B-R7 has one row of SFP-DD ports only.

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.
