Chapter 2 Connecting and Routing Cables to the HP NetServer LH 4r 4. Attach the video cable to the video port on the server. Attach the mouse and keyboard cables to the server. If you are using one keyboard, mouse, and monitor for more than one server, attach the cables for the HP Console Switch to the server ports of the video card and the mouse and monitor ports. SCSI Cable Lengths and Distances between the Server and Storage SCSI cable lengths (shown in Table 2-3 below) determine the distance between a storage unit and its associated adapter cards or controllers. Guidelines used by rack configuration tools in generating rack layouts take these distance limitations into account. Table 2-3.
