Arranging Your Workspace
Electrical Outlets and Cable Lengths
The location of electrical outlets and the length of power cords and
cables that connect to the monitor, printer, and other devices might
determine the final placement of your server.
When arranging your workspace:
Avoid the use of extension cords. When possible, plug the
server power cord directly into an electrical outlet.
Keep power cords and cables neatly routed away from
walkways and other areas where they might get kicked
accidentally.
For more information about power cords, refer to the User's
Reference.
