2.4 The Rear Panel
All cable connections are made at the ServManager’s rear panel, as illustrated
(in Figure 2-2) and described below.
Panel Label Connector Description
CPU NDB25 F Connect computers to these ports with “CPU
[N= a number Adapter Cables.” At the ServManager end,
from 1 to either 4, these cables have a DB25 male connector; at
8, 12, or 16, the other ends, they have appropriate
depending on connectors for plugging into your CPUs’ video,
which model you keyboard, and mouse ports. These cables take
you have] the signals that would normally pass between
the CPUs’ ports and the monitor, keyboard, and
mouse, and carry them between the CPUs’ ports
and the ServManager instead.
You can also connect “submaster” Serv type
switches to these ports with “ServSwitch-to-
ServSwitch Expansion Cables.” These cables have
DB25 male connectors at both ends and carry all
necessary signals from submaster units to master
units.

CHAPTER 2: Introduction
Panel Label Connector Description
CPU NDB25 F For each submaster you plan to connect, you
(continued) must have an Expansion Cable; you must have
an Adapter Cable for each CPU you plan to
connect. See Section 2.5.
NOTE
All models share the same chassis, which
has 16 CPU Nconnector slots. The extra
connector slots in the chassis of the 4-,
8-, and 12-port models are left blank, but
are protected by material mounted inside
the chassis.
MONITOR/ DB25 F Connect the shared monitor, keyboard, and
KEYBOARD/ mouse to this port using an “MKM Adapter
MOUSE Cable.” At the ServManager end, this cable has
a DB25 male connector; at the other ends, it has
appropriate connectors to plug into your
monitor, keyboard, and mouse cables. Only one
MKM Adapter Cable is needed. See Section 2.5.
RS232 RJ-12 F If you connect a more distant computer or
terminal to this RS-232 serial port, you’ll be able
to send switching commands to the ServManager
from a secondary location. You would also
connect a computer to this port to load firmware
upgrades into the ServManager.
POWER 5-pin Connect the ServManager’s power-supply cord
DIN F here. This is not a keyboard input. Power
transformers are available for 110 VAC or
230 VAC. They have center-tapped output of 17
VAC at 1.4 amps.

16
SERVMANAGERS
2.5 Cable Requirements
To connect CPUs to the ServManager, you need one “CPU Adapter Cable”
for each CPU. This cable reaches the CPU’s video-output, keyboard, and
mouse ports.
Likewise, to connect “submaster” (slave) ServSwitches to the ServManager,
you need one “ServSwitch-to-ServSwitch Expansion Cable” for each subsidiary
unit.
Lastly, you can connect the ServManager to the shared monitor, keyboard,
and mouse with a single “Monitor/Keyboard/Mouse (MKM) Adapter Cable.”
The exact variety or varieties of these cables that you’ll need will depend on
the equipment you are connecting for your application. Refer to
Section 4.1 for information on equipment that requires special cables, and to
Appendix B for the available types of stock cables and the corresponding
product codes. Also refer to Chapter 1 or the first Caution notice on
page 19 for information about maximum cabling distances.
NOTES
SVGA (over longer distances) and XGA video place special demands on
cabling that the regular MKM Adapter Cables and CPU Adapter Cables
typically cannot meet. For these applications, you should use coaxial
cables that can carry video signals not only farther but also at higher
resolutions. See Appendix B and the first Caution notice on page 19.
To share a 9515, 9517, or 9518 monitor, you will need special cabling.
Call Black Box for technical support; we can give you a quote on these
types of cable.
2.6 Equipment Requirements
If the CPUs you are controlling through the ServManager are not all of the
same type—especially if they are completely different hardware platforms
(IBM, Mac, etc.)—you will have to be careful to choose a common monitor,
keyboard, and mouse that adequately support all of the CPUs. For full details,
see Section 4.1.

CHAPTER 3: Installation
3.1 Quick Setup Guide
Figure 3-1, below, shows a basic example of connecting a CPU, a submaster, a keyboard, a
monitor, and a mouse to a ServManager unit. IBM PC equipment is shown, but the basic
principles will be similar for all equipment types. Connectors will vary depending on the types of
equipment you are installing.

3.2 Installation Procedure
This section provides complete basic instructions for the hardware setup of a
single ServManager. (For detailed instructions on the capabilities and concerns
involved in installing a cascaded ServManager system, see Section 3.3; to make
troubleshooting the installation easier, we recommend that you check the master
and each submaster as it is installed, rather than installing all units, then checking
the entire cascade.) For an illustrated example of the elements of a basic setup,
see Figure 3-1 on the previous page.
3.2.1 R ACKMOUNTING (O PTIONAL )
If you want to mount the ServManager in a 19" rack, you will need a ServSwitch
Rackmounting Kit (our product code SW728). The ServManager is pre-drilled to
accept the Kit’s rackmounting screws. If you want to mount the ServManager in a
23" or 24" rack, call Black Box Technical Support for a special quote on a 23" or
24" Kit.
3.2.2 C ONNECTING THE M ONITOR , K EYBOARD , AND M OUSE
A Monitor/Keyboard/Mouse (MKM) Adapter Cable connects your monitor,
keyboard, and mouse to the ServManager. Because various styles of electrical
connectors are used by different classes of equipment, we supply this cable in
various styles to match (see Appendix B). This cable also comes in the different
lengths supported by different applications (see Section 4.1.3, Appendix B, and
the first Caution notice on the next page).
CAUTION!
Make sure that your monitor, keyboard, and mouse can meet the
demands of your application. You might also need a special MKM
Adapter Cable if you are mixing platforms. See Section 4.1. Also, note
that the ServManager does not support dongles at the time of this
writing.
1. After you verify that the ServManager is turned OFF, plug the DB25 male
connector of the MKM Adapter Cable into the port
labeled MONITOR/
KEYBOARD/MOUSE on the ServManager’s rear panel.
2. If your common equipment is IBM type, plug the cables from your shared
monitor, keyboard, and mouse into the corresponding connectors on the
other ends of the MKM Adapter Cable. If your common equipment is Mac
or Sun type, plug the mouse cable into the keyboard, and plug the monitor
and keyboard cables into the corresponding connectors on the other ends of
the MKM cable.

19
CHAPTER 3: Installation
3.2.3 C ONNECTING CPU S
CPU Adapter Cables run from the ServManager to the keyboard port, mouse
port, and video-output port of each CPU you want to directly attach to it.
Different types of this cable fit the connectors on different computers (see
Appendix B). This cable also comes in the different lengths supported by
different applications (see Section 4.1.3).
CAUTION!
Avoid routing cable near fluorescent lights, air-conditioning
compressors,
or machines that may create electrical noise. Total length
of original Serv cable from the keyboard, monitor, and mouse to any
given CPU should not exceed 25 ft. (7.6 m). For typical equipment and
video resolutions, length of coaxial cable should not exceed 20 ft. (6.1 m)
from a ServManager to any attached device (keyboard, monitor, mouse,
CPU, or submaster). However, we do provide coaxial cable in lengths up
to 100 ft. (30.5 m), because some CPUs can drive and receive keyboard
and mouse signals at greater distances than others; consult with the
manufacturers of your CPUs about this. To go even farther, you might
want to use Station Extenders (see Appendix B) if your common keyboard
and mouse are IBM type.
1. After you verify that the ServManager is turned off and unplugged, plug the
DB25 male connector of the first CPU’s CPU Adapter Cable into the
lowest-numbered CPU port on the ServManager’s rear panel that isn’t
going to be occupied by a submaster Serv type switch. Use consecutively
higher-numbered ports for the rest of the CPUs. For example, if you
planned to put three submasters and three CPUs on an 8-port master
ServManager, you would put the submasters on ports CPU 1 through
CPU 3 (see Section 3.2.4), and you would plug the three CPUs into ports
CPU 4 through CPU 6.
2. Plug the CPU Adapter Cable’s video-, keyboard-, and mouse-port
connectors into the corresponding ports on the CPU. The CPU should
be OFF when you do this; the ServManager will automatically adjust to
the keyboard mode of IBM compatible CPUs when you power up the
CPU. Avoid plugging CPUs into the ServManager if they are already ON;
if you accidentally do so, see Section 4.3.7 to make sure the ServManager
is set for the proper keyboard mode.
CAUTION!
Do not attach docking stations for ThinkPad®or other portable
computers,
no matter what type or make, to the ServManager. At the time
of this writing, the ServManager does not support docking stations; your
ServManager system might not function properly if any are attached.

20
SERVMANAGERS
3.2.4 C ONNECTING S UBMASTERS (O PTIONAL )
To connect a submaster ServManager, Matrix ServSwitch, original ServSwitch,
etc., to a master ServManager, run a ServSwitch-to-ServSwitch Expansion
Cable (our product code EHN055 for original cable or EHN274 for
[recommended] coaxial cable) from one of the master ServManager’s CPU
ports to (one of) the submaster’s MONITOR/KEYBOARD/MOUSE port(s).
Connect the first submaster to the ServManager’s CPU 1 port and use
consecutively higher-numbered ports (CPU 2, CPU 3, and so on) for the rest
of the submasters. If you are connecting each of several Matrix ServSwitches
to two master ServManagers (see Section 3.3), connect one master to each
Switch’s MONITOR/KEYBOARD/MOUSE A port and the other master to
each Switch’s MONITOR/KEYBOARD/MOUSE B port.
Before installing an advanced configuration, please call Black Box and
discuss your application with a technician.
NOTE
Because ServManagers don’t have bus-mouse ports and can’t carry the
bus-mouse signal, they can’t function adequately as masters for
submaster ServSwitches BusM.
3.2.5 C ONNECTING THE S ERV M ANAGER ’ S P OWER S UPPLY
Making sure the connected CPUs and any connected submasters are OFF
(powered down), take the output cord of the ServManager’s power supply
and plug its 5-pin DIN male connector into the power jack on the rear panel
of the ServManager. Plug the power supply (115 VAC) or its input cord (230
VAC) into a working outlet.
3.2.6 C ONFIGURING THE S ERV M ANAGER
Unless you are using an IBM PC style keyboard and a PS/2 mouse as the common
keyboard and mouse, are using all IBM PC type CPUs, and are not cascading, you
will have to configure the ServManager. To do so, use its front-panel display and
keypad:
1. Push the ON/OFF button on the front of the ServManager to power up
the unit, and wait for a few seconds for the unit to complete its power-up
procedure. The display should show the firmware revision and some
diamonds as it performs its power-up tests, then should connect the
keyboard, monitor, and mouse to the CPU on port CPU 1. The default
name “CPU 1” should be shown on the first line of the display, and that
CPU’s power status should be shown on the second line.

21
CHAPTER 3: Installation
2. Press the MENU key to access the configuration menu. A configuration
option will appear; the order in which options appear will depend on the
revision level of the unit’s firmware. Press the up-arrow to cycle through
the available options. When you reach the Max Ports option, enter the
maximum number of ports in your system if it will differ from the
displayed default.
3. Press the up-arrow until you get to the Keyboard option. Press the
ENTER key to access the available settings for the Keyboard option. Use
the up-arrow to scroll through the choices of PC, Mac (Apple), or Sun.
