error:Uplink FRU module ports cannot be used as Stackwise Virtual Links

[Lazerunner22]

Dear 

I have to C9500-40X switch, each device with a network module C9500-NM-8X and I find the datasheet of this module can support Stackwise

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst9500/software/release/16-11/configuration_guide/ha/b_1611_ha_9500_cg/configuring_cisco_stackwise_virtual.html

So I had connected two cables (SFP-H10GB-CU5M=) on last two ports on NM-8X module between the two C9500-40X devices

But When I config the commend under the interface view, displayed a error as below,

cisco(config-if)#stackwise-virtual link 1
Uplink FRU module ports cannot be used as Stackwise Virtual Links

 May I ask how can I fix it?

Hi,

It appears that 9500-NM-8X can not be used for Stackwise Virtual link. See link:
