The device supports only transceivers that are qualified for Brocade products. If you use an unqualified transceiver, the
switchshow command output shows the port in a Mod_Inv state. The issue is also logged in the system error log.

On Gen 6 platforms, 16G QSFPs may sometimes negotiate the link speed to 8G when a breakout cable is connected.
To avoid this, disable and then re-enable the port that negotiated the speed to 8G, or you must connect the cable to the
QSFP first and then install the QSFP into the switch.
Perform the following steps to insert a QSFP transceiver:
NOTE
QSFP transceivers have pull tabs rather than bails. Always use the pull tab to insert or remove the QSFP
transceivers, since the QSFP might be hot.
1. Use the pull tab on these transceivers 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.

2. 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.
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 that is intended for another type of transceiver
into a regular QSFP transceiver. You may damage the cable as well as the transceiver.
