9. Place the attached cable clamp at an appropriate

location at the back side of the server switch unit and

then fix the operation panel connection cable so that it

will not loosen.

Adjust the cable length

using the cable clamp.

Console panel connection cable

This portion should not be slackened.

DESKTOP INSTALLATION ON THE

SERVER SWITCH UNIT

Attach four rubber feet (shock absorber) to the

bottom of the server switch unit when installing for

desktop use, as shown in the figure below.

CABLE CONNECTION

The server switch unit is connected with

a server through the K410-118 or

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.

(Refer to

User's Guide for detail).

SIMPLEX CONNECTION -CONNECTING

WITH EIGHT OR LESS SERVERS

Take the following steps to connect cables.

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)

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

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 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".

A sample construction is illustrated shown below:

the server switch unit is installed in a rack and 15

servers are connected in the cascade.

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.).

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.
