RACK

The server switch unit should be mounted on a rack following the proper procedures listed below;

1. Remove the console connection cable from the rear of the unit. Remove the four shock absorbers located at the bottom of the unit (if installed).

Remove the four flat head screws from the left and/or right ends of the console panel. (Keep these screws for future use.)

3. Remove the console panel from the unit and install

CABLE CONNECTION

K410-119 cable sold separately. The K410-118 cable has a USB connector and a

LCD connector on one end, and D-Sub 15-pin connector on the other end. The K410-119 cable has two PS/2 connectors (for keyboard and for mouse, distinguished by different colors and icons) and a LCD connector on one end and D-Sub 15-pin connector on the other end.

Use the dedicated cables listed below to connect the server switch unit with the server. User's Guide for detail).

The server switch unit is connected with a server through the K410-118 or

(Refer to

SIMPLEX CONNECTION -CONNECTING

5. Fix the cables to the rack with the attached tie

wraps.

6. After confirming that all the connections are properly in place, power ON the servers sequentially. Select each of the servers to confirm that it has is

started normally and is set correctly.

7. If the keyboard, mouse, and/or display monitor are not set correctly, set and start each device again.

CASCADE CONNECTION -CONNECTING

WITH NINE OR MORE SERVERS

You can add N8191-10F server switch unit by using the dedicated connection cable (K410-119 (1A)) to each server port of the server switch unit or N8143-69 console unit. Such the connection is called cascade connection.

WITH EIGHT OR LESS SERVERS

Take the following steps to connect cables.

With eight N8191-10F server switches in cascade connection, you can select a console from up to 64 servers. In cascade connection, the installation area can be greatly reduced since it requires only one console.

The N8191-10F server switch unit in which the console is connected is called the "master", and the N8191-10F server switch units connected to each port of the master unit are called "slaves".

1. Connect seven servers to the ports 1 through 7 of the master server switch unit according to the procedures in "SIMPLEX CONNECTION -CONNECTING WITH EIGHT OR LESS SERVERS" described earlier(Connection (1), (2) in the figure above.). Power cords for the server switch unit, the servers, and the console must be connected later.

2. Connect the eighth port of the master server switch unit to the Keyboard, Mouse, and Console connectors (console port) of the slave unit using the dedicated cable (K410-119(1A)), connecting the slave side first(Connection (3), (4) in the figure above.).

3. Connect the remaining eight servers to the slave server switch unit according to the procedures in "SIMPLEX CONNECTION

-CONNECTING WITH EIGHT OR LESS SERVERS" described earlier(Connection (5), (6) in the figure above.).

4. After completing the connections of the server switch unit with the servers, connect the keyboard, mouse, and display unit to the Keyboard, MOUSE, and Console connectors of the master server switch unit(Connection (7) in the figure above.).

Shock absorbers

1. Connect the keyboard/mouse and display connectors of the first server through the dedicated cable (K410-118 or K410-119) to the server switch unit, connecting first the server switch unit side, then the server side. ((1), (2) in the figure above).

2. Connect servers two to eight as necessary. ((1), (2) in the figure above).

3. When all servers are connected to the server switch unit, connect the keyboard, mouse, and the display units to the KB, MOUSE, and CONSOLE connectors. ((3) in the figure above.)

4. Finally, connect the power cords of the servers and display unit and the AC cord of the server switch unit into the AC outlet. ((4) in the figure above)

A sample construction is illustrated shown below: the server switch unit is installed in a rack and 15 servers are connected in the cascade.

5. Finally, connect the power cords of the servers and the display unit and the Power cord of the server switch unit to the Power outlet(Connection (8) in the figure above.).

6. Fix the dedicated cables and Power cords with the attached tie wraps.

7. After confirming that all the connections are properly in place, power ON the servers sequentially.

8. If the keyboard, mouse, and/or display monitor are not set correctly, set and start each device again.
