Transceiver and Cable Recommendations


The Cumulus Networks Hardware Compatibility List (HCL) provides a list of pluggables that are recommended for use with systems running Cumulus Linux. The list includes:

  • All Cumulus Express components
  • Pluggables qualified by Cumulus Networks Engineering

The HCL provides a list of recommended pluggables for each platform. That list identifies the Cumulus Linux versions that support each recommended pluggable. The HCL includes pluggables qualified by Cumulus Networks Engineering.

While Cumulus Networks recommends using the pluggables listed on the HCL, Cumulus Networks also provides this procedure for qualifying a non-recommended pluggable yourself. If you decide to try out a pluggable that Cumulus Networks does not recommend, Cumulus Linux does not actively prevent the pluggable from functioning. Cumulus Networks does not restrict the use of self-qualified pluggables; however, we do not provide support for any issues that arise from a self-qualified pluggable. If you have concerns about a pluggable that is not listed, please contact your Cumulus Networks sales team.


This support portal has moved

Cumulus Networks is now part of the NVIDIA Networking Business Unit! The NVIDIA Cumulus Global Support Services (GSS) team has merged its operations with the NVIDIA Mellanox support services team.

You can access NVIDIA Cumulus support content from the Mellanox support portal.

You open and update new cases on the Mellanox support portal. Any previous cases that have been closed have been migrated to the Mellanox support portal.

Cases that are still open on the Cumulus portal will continue to be managed on the Cumulus portal. Once these cases close, they will be moved to the Mellanox support portal.
