A soulution to interface change speed to 1000 failed of S6520X-SI series switches

Null

HCI HDM port connect to the interface module, no led light up，and interface module 10G unable change speed to 1000

The command line shows the operation is not supported . 

Therefore, it is very likely that the module or device is not compatible with the operation.

Refer to relevant data，it shows that LSWM4SP2PM and LSWM2XGT2PM Interface module expansion cards When used for S6520X-SI series switches, ports on the interface module expansion cards can only work at 10 GBIT/s.

So，that is the reason why we can not change speed to 1000.

It is a module incompatibility problem，so we can solve it through changing module that is compatible for the device.

You can use these modules, they are compatible for S6520X-SI, and they support 10GE.

Or you can use SFP+ port of front panel

please to check table 4-3 and table 4-5 of this link https://www.h3c.com/en/d_202107/1429840_294551_0.htm to comfirm your SFP+ module is compatible.
