Do not use any unauthorized interface cable. Use only interface cables specified by NEC and locate a proper device and connector before connecting a cable. Using an unauthorized cable or connecting a cable to an improper destination may cause a short circuit, resulting in a fire.
Connecting with Eight or Less Servers Connect the cables to the server switch unit in the following procedure. (The figure below shows an example of the server switch unit installed in the rack with eight servers connected.) 1. Connect the keyboard/mouse connector and display connector of the first server through the dedicated cable (K410-118 or K410-119).
Page 80
2. Provide the cable connections for the second to eighth servers. Connect the interface cable to the server switch unit side first, then the server side. Check 3. When all servers are connected to the server switch unit, connect the keyboard, the mouse, and the display unit to KB, MOUSE, and CONSOLE connectors ( in the figure above).
Connecting with Nine or More Servers You can add another server switch unit by connecting the dedicated connection cable (K410-119 (1A)) to each port of the server switch unit. Such the connection is called cascade connection. With nine server switch units (maximum configuration) in cascade connection, you can select up to 64 servers. In cascade connection, the installation area can be greatly reduced since it requires only one console.
Page 82
1. Connect the seven servers to the ports 1 through 7 of the master side according to the procedures in "Connecting Eight or Less Servers" described earlier. (Connect in order of AC cords for the server switch unit, the servers, and the console must be connected later. 2.
