INSTALLATION

Organizing the system

It is recommended that before any ServSwitch MultiVideo configuration or
cable connections be made, plan how the system will be laid out, the
placement of the CPUs, the placement of the ServSwitch MultiVideo, and
the placement of the monitors. Take into consideration the cable lengths
needed to connect to the KVM station, each CPU, and each monitor.
Identify which computer will be connected to each CPU connector and if
that computer uses a PC mode 2 keyboard and PS/2 mouse. If not, the
CPU port should be pre-configured to change the default keyboard and
mouse types to the correct settings.

If you are adding Slave units to expand your system, it is important that you
understand the width command, especially if your system consists of
different models (2-CPU ports, 4-CPU ports, and 8-CPU ports). For
example, if your system consists of an 8-port master, two 8 -port Slave units
and one 4-port Slave unit, and you program the expansion width to 8, there
will be 4 blind ports on the 4-port unit. In other words, the 4-port unit will
appear to the system as having 8 CPU ports. CPU ports 5-8 are blind ports.
If you program the expansion width to 4, then only CPU ports 1-4 on the 8­port Slave units can be accessed. In systems that have a mixture of
models, it is recommended that the width value be set to the number of
CPU ports on the Slave unit with the most CPU ports.

Installation – Single unit

This section explains how to connect and initially configure the ServSwitch
MultiVideo. If you are cascading two or more units together, please refer to
the Cascade installation section.

Connecting the KVM station

Connect the KVM station’s keyboard, video monitor, and mouse cables to
the corresponding connectors on a KVM cable as shown in Figure 8. The
KVM cable should have the correct connector types for the equipment
used. Connect the DB25M connector into the connector labeled KVM-1 on
the rear panel. If a serial mouse is used on a KVM station, all mice in the
system (on every computer) must be a serial mouse.

Apply power

For the “M” chassis, connect the power transformer to a 110/220-volt
source and to the DIN 5F power adapter connector on the rear panel. Press
the ON/OFF button in the front panel once to turn on the unit. For the “B”
and “C” chassis, connect a power cord to 110-220-volt source and to the
IEC320 connector on the rear panel. Press the rocker switch to the ON
position.

SERVSWITCH MULTIVIDEO INSTALLATION AND OPERATIONS MANUAL

22

The green POWER LED will turn on and the power-on diagnostic will run.
Wait until the SELECT 1 LED on the front panel lights before entering any
configuration or switching commands. This assures that the internal
diagnostics have completed. If, for any reason, you need to cycle power on
a unit, turn the power off and wait 10 seconds before re-applying power.

On initial power-up, computer 1 is automatically connected. The SELECT 1
LED on the front panel will light indicating that the KVM station is connected
to the CPU-1 port.

Connecting the computers

Each computer that is connected to the ServSwitch MultiVideo is connected
using a CPU cable. This cable connects from the DB25M CPU port on the
rear panel to the keyboard, monitor, and mouse ports on a CPU (See
Figure 8). The keyboard, monitor, and mouse connectors on the CPU
cable should be compatible with the corresponding ports on the computer
being connected. The additional video ports on the CPU are connected to
the DB25F connectors using a DB25F to HD15 cable. For ease of
installation and configuration, it is recommended that the computers’ power
be off at this time. When a computer is booted, the ServSwitch MultiVideo
can automatically determine the keyboard and mouse types of the
connected CPUs.

If removing power from a computer is not feasible, the ServSwitch
MultiVideo should be pre-configured, if needed, before the CPU is
connected. The default keyboard and mouse types set for each CPU port
are; PC mode 2 keyboard and a PS/2 mouse. If the computer being
connected does not use a PC mode 2 keyboard and a PS/2 mouse, pre­configure the CPU port for the correct keyboard and mouse type. Once the
CPU port has been configured, the computer can be connected to the
ServSwitch MultiVideo. This procedure should only be done if the
computer’s keyboard and mouse can be disconnected and re-connected
with power applied to the computer without affecting the interface.

To pre-configure a CPU port, perform the following:
(Note: the computer should not be connected to the CPU port at this time)

1. Apply power to the Unit and the KVM station monitor.

2. Switch to the CPU port to pre-configure by pressing and releasing the
left control [Ctrl] key, type in the CPU port number, and press [Enter].

3. Issue the “Set mode” command. (Ctrl,Mnn,[Enter])
Example : If the keyboard is a PC mode 3 keyboard, the command
would be Ctrl,M3,[Enter] (See Table 3)

4. Select the correct mouse type from Table 4.

5. Issue the “Set mode” command (Ctrl,Mnn,[Enter])
Example: if the mouse type is a serial 2 button mouse, the
command would be Ctrl,M7,[Enter]

6. Issue the “Keep” command to save the new values
(Ctrl,K,[Enter])

7. Perform steps 2 through 7 for each CPU port that needs the default
keyboard and mouse changed to a different type.

SERVSWITCH MULTIVIDEO INSTALLATION AND OPERATIONS MANUAL

Installation – Cascading units

The ServSwitch MultiVideo units can be cascaded together to expand the
number of computers that can be accessed from the KVM station.
When cascading units, one unit becomes the “Master” unit and all others
are “Slave” units. Each computer and video port on the master unit can be
connected to a Slave units’ KVM and video connectors. Figure 9 illustrates
the addition of two 4-port Slave units. Using 8 port units, the master unit can
connect to 8 Slave units for a total of 64 CPU ports.

The ServSwitch MultiVideo “Master” must be configured to properly
manage the cascaded units. The maximum number of computers, the
number of Slave units connected, and the number of ports (width) on the
Slave units must be entered and saved. In the example in Figure 9, the
maximum computer entry would be 16, the number of Slave units is 2, and
the number of ports, or width, on each Slave unit would be 8. It is
recommended that all Slave units have the same number of computer ports
but it is possible to chain different models.

The “Maximum computers” value is figured as follows:
If all Units in the system have the same number of CPU ports, (no mixed
models) then you can count the CPU ports used to connect to the
computers. The ports on the master unit used for expansion should not be
counted.

If there is a mixture of models in the system, the “Maximum computers”
value is the “Width” value times the number of Slave units plus the CPU
ports on the master unit that are not used for expansion. Valid entries are 2
to 64.

In the example in Figure 9, the width value is 4, the number of Slave units is
2, and the CPU ports on the master unit that are not used for expansion is

2. The Maximum computers value would be 4 x 2 + 2 or 10.
To configure the “Maximum computer”, “Units”, and “Width” values, connect

a KVM station to the Master unit. Power on the KVM monitor and the
Master unit. Wait until the SELECT 1 LED lights.

To enter the “Maximum computer” value, press and release the left control
[Ctrl] key,P,nnn,[Enter], nnn=Maximum computers value.

The “Units” value is the total number of Slave units in the system. To enter
the “Units” value press and release the left control [Ctrl] key,U,nn,[Enter],
nn=number of Slave units. Valid entries are 1-8.

The “Width” value is the number of CPU ports on a single Slave unit. To
enter the “Width” value press and release the left control [Ctrl]
key,W,nn,[Enter], nn=number of ports on an Slave unit.
Refer to “Organizing the system” for further information.
Save changes by pressing and releasing the left control [Ctrl] key, K, [Enter]

Appendix D. Rack mount instructions

The ServSwitch MultiVideo can be mounted in a rack using the Rackmount
kits from Black Box.

The optional rack mount kit includes the following items:

¾ Two black anodized mounting brackets.
¾ Four 6-32 x 3/8” flat head mounting screws.

To rack mount your ServSwitch MultiVideo, attach the two rack mounting
brackets to your unit with the short flange against the unit using the four
screws provided. Secure the mounting brackets to the rack using the
appropriate size bolts, nuts and lock washers. Using hardware other than
that provided could cause damage to the electronics and/or result in loss of
mounting integrity. Do not over tighten the screws used to mount the unit to
the mounting brackets.

The following general guidelines should be observed when installing your
unit into a rack.

1. The ServSwitch MultiVideo is designed to work in an ambient
temperature of 0

ο

C to 55

ο

C (32

ο

F – 131ο F).

2. Do not block power supply vents or otherwise restrict airflow when
rack-mounting this unit.

3. Mechanical loading of the rack should be considered to prevent
instability and possible tipping over.

4. Tighten all connectors securely and provide adequate strain relief for
all cables.

5. Provide a grounded power source to all units. Pay special attention to
overall branch circuit load ratings before connecting equipment to this
source. Overloaded circuits are potential fire hazards and can cause
equipment failures or poor performance.
