When Global Technical Support requests a connection to the TECH port of a physical XtremIO X2 XMS, the service machine should be connected to the MGMT ETH0 port on the server. This port is typically used for management purposes and allows for the necessary communication between the service machine and the XtremIO X2 XMS for technical operations and support.
