2. Position the cable so that the key (the ridge on one side of the cable connector) is aligned with the
slot in the transceiver. Insert the cable into the transceiver until the latching mechanism clicks.
Note
If your transceiver has an integrated cable, you do not need to install a cable.
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 insert any unsupported cable intended
for another type of transceiver into a regular QSFP28 transceiver. You may damage the
cable as well as the transceiver.
3. Organize cables to avoid covering LEDs and air vents so that LCs can be removed. Refer to
on page 65 for more information.
Replacing a QSFP28 transceiver
Complete the following steps to remove and then install a new QSFP28 transceiver.
1. Remove any cables that are inserted into the transceiver.
Note
If your transceiver has an integrated cable, you cannot remove the cable.
2. Grasp the transceiver pull tab and gently pull the transceiver straight out from the port.
Note
Grasp the pull tab near the body of the transceiver to reduce the chances of bending the
pull tab. As the transceiver may be hot, always use the pull tab and avoid touching the
transceiver body.
3. To insert the replacement transceiver, use the pull tab to carefully push the transceiver into the port.
Transceivers are keyed so that they can only be inserted with the correct orientation. If a transceiver
does not slide in easily, ensure that it is correctly oriented. Gently push the correctly oriented
QSFP28 transceiver until the latching mechanism clicks.
Note
The following figure uses a generic interface module. Your interface module might look
different.
