I just run into an issue with the Intel recommended AFBR-709DMZ-IN2 module which is not working in Dell C6420 servers provided with X710-DA2 for OCP card.
Card will not PXE boot and when I load the Linux latest i40e driver 2.4.10 I'm getting the following message:
[ 205.628138] i40e 0000:18:00.1: Rx/Tx is disabled on this device because the module does not meet thermal requirements.
[ 205.628858] i40e 0000:18:00.1: Refer to the Intel(R) Ethernet Adapters and Devices User Guide for a list of supported modules.
X710 card has DELL OEM firmware version 18.5.17.
I downgraded the firmware to version 18.6.3 but still the same issue.
This card is working well with module Cisco SFBR-5716PZ with both firmware.
Thank you for posting in Intel Wired Ethernet Communities. The AFBR-709DMZ-IN2 is listed as a https://www.intel.sg/content/www/xa/en/support/articles/000007045/network-and-i-o/ethernet-products.... Compatible SFP Module for Intel X710 adapters. Since this is an OEM Dell X710 adapter the supported modules may be different. Have you checked with Dell if this is a supported SFP module for the OEM version? If you have any other questions please do not hesitate to ask.
Thanks for you quick reply. We are checking now with DELL as they delivered as a working solution which definitely is not. At the moment they will send us a different transceivers which hopefully will work.
I was just curious if Intel had any other complains regarding this type of cards and SFP+.
Thank you for the reply. Intel retail adapters with the compatible SFP modules generally work. Usually issues occur when an unsupported module is used by mistake. Dell would be able to best provide you the module to use with this adapter, and if AFBR-709DMZ-IN2 is compatible. If you have any other questions please let us know.
Thank you for the reply. Glad Dell was able to help you out with this. We will check back when you get the module to see if this solves the issue. Did they give you a delivery date? Let us know if you have any questions.
