What is the proper way to set up my Z440 Workstation for the first time?

Connect the mouse, keyboard, and power cord to the workstation, then connect the monitor. Connect other peripheral components like a printer according to their instructions, connect a network cable to a router or LAN device, and plug the workstation and monitor power cords into an AC outlet. Be sure to use a grounded three-pin outlet and do not disable the power cord grounding pin.
