| 2. Modify the module_db_update() to call get_module_admin_status() to check the config module. If the module_cfg_status is not set to down, then populate the CH-TBDASSIS_FABRIC_ASIC_TABLE. Otherwise, just ignore it even the SFM module is present. This mechanism prevents the event is triggered in the swss.sh when admin_status is set to down state. | ||

We may need to consider sonic-mgmt test to cover this. The tests should cover validating effect on thermal and pci devices.

@abdosi @judyjoseph I have update the document with investigation of the Impact of PCIed and Thermal sensors. Based on the current implementation, there is NO impact. Please review it |

| # 3 Impact and Test Considerations | ||
| ## 3.1 Impact of the PCIed and Thermal sensors | ||
| For PCIed, based on the investigation, the current design of the Fabric module shutdown has NO impact on the PCIed. The PCIed current checks the basic PCI components. For the Fabric slot which is shutdown, if platform supports PCI on the Fabric card, it should check if its power is on that particular card before it is added to the PCIe check. That is how is handled in the Arista vendor code. |

When Fabric is shutdown through CLI, the Vendor code needs to modify the pci device list and remove the the device from list. We would also need support to be able to update this list dynamically. Currently, it's loaded during boot with the start of pcied daemon. If the list is updated, this process needs to restart in the current implementation.
