Verifying the operation of new transceivers

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 QSFP
transceiver until the latching mechanism clicks.

4. Position a 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.
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.
