The interface randomly goes down after connecting the SFP-GE-T-D optical-to-electrical module to the S6520X-54XG-EI-G

During IRF setup for field devices, after inserting optical-to-electrical modules to connect to the peer server, the interfaces with these modules spontaneously go down and do not automatically recover to up status. Recovery requires re-plugging the network cable and module, or in some cases, just re-plugging the cable. According to field feedback, this issue has occurred multiple times and is not limited to a specific interface—all interfaces using this optical-to-electrical module are affected.

Checked the official website compatibility and found it is compatible

After research & development (R&D) analysis, this issue is a version problem. 7706P03 does not have the corresponding patch and needs to be upgraded to R7763P04 or the latest annual version R7756P10.

It is recommended to upgrade to the latest annual version R7756P10

Issue phenomenon: During device operation, the port with an optical module inserted may randomly go down and fail to recover automatically, or there may be random false diagnostic alarms from the module.
Condition: The device has an optical module inserted and runs for a long time
Note: Modules are prone to issues from WTD vendor.

Upgrade to R7763P04 or the latest annual version R7756P10 to resolve
