All unused SFP ports on X670G2-48x is showing local-fault on link state even though it has nothing in it

    I have a X670G2-48x, I've been trying to add in an edge node via SFP_SR onto it and all the unused ports link state are saying local fault. They have never been used nor have had a vlan attached to them. This is only happening to the unused ports on slot 3, which is also the master.
    The other ports on slot 3 that have been working before today are fine
    Port: 3:18
    Virtual-router: VR-Default
    Type: NONE
    Random Early drop: Unsupported
    Admin state: Enabled with 10G full-duplex
    Link State: Ready (local fault)
    Link Ups: 0 Last: --
    Link Downs: 0 Last: --
    VLAN cfg:
    STP cfg:
    Protocol:
    Trunking: Load sharing is not enabled.

    XOS 15.7.1.4

    I believe that just means it is not seeing any light.
    Have you tried patching in fiber?
    Do you know your fiber is passing light cleanly

    What is the output of?
    show port 3:x transceiver info

    I don't think so as another port on slot 1 that is unused and empty is showing a link status of Ready
    Port: 1:29
    Virtual-router: VR-Default
    Type: NONE
    Random Early drop: Unsupported
    Admin state: Enabled with 10G full-duplex
    Link State: Ready
    Link Ups: 0 Last: --
    Link Downs: 0 Last: --
    VLAN cfg:
    STP cfg:

    Even if I patch a fibre the link status doesn't change.

    Does it see light when you run the command I suggested above?

    Do you have the same type/brand optic inserted in both ports?

    I am not near my lab so can't test anything myself.
