Any ideas? Do we have to configure link speed in opensm.conf or partitions.conf?
opensm.log didnt recognized that we pluged in a new interface and we got no link signal.
Thank you for posting your question on the Mellanox Community.
Based on the information provided, the switch you are using is an unmanaged switch. Based on the supported InfiniBand speed, the switch will auto-negotiate the correct speed if the transceiver is supported.
Unfortunately, the transceiver you are using is Non-Mellanox transceiver, which we do not support as the transceiver is not tested by us in combination with the switch.
The supported and tested transceivers for this switch can be found through the following link -> http://www.mellanox.com/products/interconnect/infiniband-optical-transceivers.php
If you experience new issues when using a supported Mellanox transceiver in the switch, please do not hesitate to open a Mellanox Support ticket through email@example.com
Thanks and regards,
