  • In order to isolate the issue further, below steps need to be implemented-
    • Perform a physical reseat of the blade on slot 8  and Reboot the switch.
    • If issue still persists, need to ensure that the blade is  correctly seated in the chassis and the only way of checking this is to lay a flat device across the front of the chassis, for example using a metal-edged ruler.
    • If any of the blades are not completely ‘flush’ or flat across this chassis face then we have a problem with a blade not correctly seated.
    • The Onsite/field engineer will need to check the top, middle and bottom of the front of the chassis to ensure the blades are perfectly ‘flat’. If the ruler shows any evidence of not being flat across all blades then there is a problem with the blades not being seated correctly.
    • In this case, we need to power the chassis off, and carefully remove and reseat the blades to be completely flat across the front.
