THE SERVSWITCH™ FAMILY
1
Welcome to the ServSwitch Family!
Thank you for purchasing a BLACK BOX®ServSwitch™Brand KVM switch! We appreciate your
business, and we think you’ll appreciate the many ways that your new ServSwitch
keyboard/video/mouse switch will save you money, time, and effort.
*
Our ServSwitch family is all about breaking away from the traditional, expensive model of
computer management and display. You know, the one-size-fits-all-even-if-it-doesn’t model that
says, “One computer gets one dedicated monitor or user station, no more, no less.” Why not a
single user station (monitor, keyboard, and mouse) for multiple computers—even computers of
different platforms? Why not a pair of user stations, each of which can control multiple
computers? Why not many monitors or user stations for the same computer? Why not access or
display any of your computers, anywhere in the world, with any of your monitors or user stations?
With our ServSwitch products, there’s no reason why not. We carry a broad line of robust
solutions for all these applications:
• Do you have just two PCs, and need an economical alternative to keeping two monitors,
keyboards, and mice on your desk? Or do you need to share dozens of computers, including a
mix of IBM
®
PC, RS/6000®, Apple®Macintosh®, Sun Microsystems®, and SGI®compatibles
among multiple users with different access levels?
• Do you have to send video from one computer to two different local monitors? Or do you
need to send video from multiple computers to dozens of monitors both near and far?
• Does your switch have to sit solidly on a worktable and use regular everyday cables? Or does it
have to be mounted in an equipment rack and use convenient many-to-one cables?
No matter how large or small your setup is, no matter how simple or how complex, we’re
confident we have a ServSwitch system that’s just right for you.
The ServSwitch™ family from Black Box—the one-stop answer for all your KVM-switching
needs!

2. Introduction
2.1 Overview
With the ServSwitch Multi™, multiple users at your site can operate sets of IBM®PC compatible, Apple
®
Macintosh®, Sun Microsystems®, and other computers at the same time. Each ServSwitch Multi Expansion
Chassis (product code KV160A-R2)—the preferred “starting” model for mid- to large-scale applications—
supports as many as 14 external connections through plug-in cards. You can connect computers,
keyboard/monitor/mouse/etc. user stations, terminals, and other ServSwitch Multi units to the system through
those cards. Front-panel LEDs show which of the Chassis’ card slots is “on line” (has a card installed that is
connected to powered equipment) and, of these, which slots are currently selected by system users.
ServSwitch Multi Base Units (KV150A-R2) are like the Expansion Chassis, but are more suited for use in
small-scale applications such as those involving a single Multi unit that doesn’t require frequent
reconfiguration. In the Base Units, one of the plug-in card slots is replaced with a “local console module,” a
user-station port with dedicated front-panel connectors for a nearby keyboard, monitor, mouse, and other
peripherals. (Unfortunately, the ServSwitch Multi’s on-screen display menus can’t be used with this local
console.) The Base Unit has front-panel pushbuttons for card-slot selection, LEDs that show which slots are
currently selected by system users, and a two-character alphanumeric display that shows which port is currently
selected by the local console.
The ServSwitch Multi MX (KV155A) is a smaller version of the Base Unit with four card slots plus a local
console, without the alphanumeric display. It only supports two video/control pathways instead of the usual
four. It’s intended for desk- or countertop use only in individual or local-cluster applications.
The ServSwitch Multi SB (KV162RA) is virtually identical to the Expansion Chassis, except that it supports
eight video/control pathways instead of the usual four, so that users can independently access as many as eight
of the attached computers.
The ServSwitch Multi Hub (KV170RA) is designed to be a centerpiece for the very biggest applications. It has
nine slots exclusively for special concentrated Transmit and Receive Modules (KV1701C and KV1702C
respectively) that have 16 ports each. Using the Hub can greatly reduce the number of regular Expansion
Cards and expansion cables needed for Multi systems with large numbers of computers and users. The Hub can
be controlled with front-mounted pushbuttons and a 4-x-20-character display.
CHAPTER 2: Introduction
15
2.2 Features and Benefits
Here are some of the ServSwitch Multi’s features:
• Automatic booting of all attached computers. ServSwitch Multi’s AutoBoot feature boots all of your
attached computers during initial power-up or after a power failure. All computers are booted transparently
and simultaneously, eliminating the need for operator intervention. Computers may be powered up one at
a time or all at once.
• Built-in computer-port scanning. You can use the ServSwitch Multi’s built-in scanning feature to
automatically monitor or scan all of your attached computer channels sequentially without intervention.
When the ServSwitch Multi detects keyboard or mouse activity, scanning is suspended until all activity stops.
Scanning then resumes with the next computer in sequence. The “dwell time” (the length of time each
computer channel’s video output remains on the screen) is configurable and can be changed at any time.
• Multiplatform support. The ServSwitch Multi adds multiplatform capabilities to your system by
simultaneously supporting any combination of IBM PC compatible, Mac
®
, Sun®, IBM RISC System/6000
®
(RS/6000®), Silicon Graphics®(SGI®), or Hewlett-Packard®(HP®) computers. Now you can switch easily
among your PCs, Mac
®
computers, and workstations with the push of a button. Use any type of keyboard
and mouse to access any computer in the system. For example, a PC keyboard and mouse can operate a Sun
workstation almost as easily as a Sun keyboard and mouse will operate an attached PC.
• Multiuser support. Instead of just one user having access to the attached computers, the ServSwitch Multi
allows up to two, four, or eight users simultaneous access to different computers in the system. If two or
more users need access to the same computer, they can “share” access to it through the switch. “Sharing”
means that multiple users can switch to the same computer at the same time. Everyone can see that
computer’s video, but only one can enter data at any given moment; a timeout scheme is used to arbitrate
user contention for keyboard and mouse control.
• Expansion capability. You can manage even large numbers of computers from a limited number of user
stations by installing expansion transmit and receive cards in multiple ServSwitch Multis, then cabling those
cards together to form a cascaded system. In fact, such a system with one master user station can control
literally thousands of computers this way.
• Multimedia and serial-communication support. With the proper peripheral equipment and cabling, every
user in a ServSwitch Multi system can access and control the attached computer equipment not only
through their dedicated keyboard, mouse, and monitor, but also through a dedicated microphone, stereo
speakers, and/or RS-232 serial port. Modems, serial printers and scanners, and other serial devices are
accessible through the serial port; if you attach a PC to this port, you can view the Switch’s system
configuration or firmware-revision level, or download upgraded firmware into the Switch.
• On-screen management and multilevel security. If you install User Cards with On-Screen Display (our
product code KV2550C-R2) in your system, you can use a variety of functions through on-screen windows:
Name your servers for easy recognition, then select them from a pop-up menu; edit channel names and
addresses; scan; broadcast; or even implement password-based security. With the security options, you can
assign video only, video/keyboard/mouse, or full access privileges to users, as well as setting an inactivity
timeout.
• Modules “Keep Alive” with interface power. The ServSwitch Multi’s CPU-Interface Card modules have
“Keep Alive” circuitry through which they can draw power from the attached computers if they become
detached from the ServSwitch Multi or if the ServSwitch Multi loses power. Because the modules remain
powered in such an emergency, your computers don’t lock up needlessly.
SERVSWITCH™ MULTI
16
• Modules are hot-swappable. Because the ServSwitch Multi is a component-based switch, all of its modules
are field-replaceable plug-in boards which can be added or replaced without disassembling or even
powering down the system. This “hot-swap” or “hot-plug” capability makes installing, configuring, and
maintaining the unit much simpler.
• Firmware is flash-upgradable. You can update the Switch’s firmware without having to power down the
Switch or remove any installed Cards. The latest firmware is always available through our Web site,
www.blackbox.com.
• Rackmountable. All ServSwitch Multi models except the MX can be mounted in a standard 19" equipment
rack. The SB and Hub models ship ready to mount; the Base Unit and EXP models can be mounted with
our optional RMK19L and RMK19LE rackmount kits respectively (see Appendix F).
2.3 A Typical Application
Figure 2-1 shows a very basic but typical application for the ServSwitch Multi (a Base Unit, in this case):
Figure 2-1. A three-computer, three-user-station ServSwitch Multi system.
* All monitors are multisync types because each shared monitor in a ServSwitch Multi system must be capable of
synchronizing with the video output of any attached computer.
† If you use Macintosh console equipment in a multiplatform system, you must use a PC-style serial mouse. This is
because, although the remapping functions of the ServSwitch Multi (see Section 8.4) make it possible for a Mac
keyboard attached to the Switch to emulate the functions of a PC or Sun keyboard, at the time of this writing there is
no way for a one-button Apple mouse attached to the Switch to emulate a mouse with more buttons.

2.4 Limitations and Restrictions
Keep these things in mind as you plan, design, install, and operate your ServSwitch Multi system:
• The ServSwitch Multi supports these models of mice:
– Microsoft serial or PS/2 mouse (including the IntelliMouse
®
);
– Microsoft OEM style serial mouse;
– Logitech
®
Mouseman®and Trackman®;
– IBM PS/2 style mouse;
– Kensington
®
PS/2 or ADB mouse;
– Mouse Systems (PC Mouse);
– Sun Microsystems Laser mouse; and
– Apple ADB mouse.
Other manufacturers’ mice generally operate with the ServSwitch Multi, but we cannot guarantee that any
given mouse will. If you experience problems using an untested mouse, contact Black Box Technical
Support with the manufacturer and model number of the mouse.
• Monitors at all user stations must be capable of synchronizing with any attached computer’s video rate. If
you are unsure whether your monitors have multisync capability, consult the monitor documentation or
contact your dealer.
• Use only Black Box supplied cable with the ServSwitch Multi. Poorly constructed or miswired cabling will
diminish video quality and could possibly damage your equipment.
• The ServSwitch Multi supports all externally powered speakers that use 3.5-mm miniplugs. We recommend
that you use powered speakers with the ServSwitch Multi for best performance.
• Use “mono” microphones with 3.5-mm miniplugs with the ServSwitch Multi. Powered microphones are not
recommended; if a computer channel is selected that supplies power to the microphones, the microphone
volume might be muted on that channel.
• The ServSwitch Multi’s CPU and User Cards autosense EIA/TIA RS-232 serial devices using any data format
and hardware, software (“inband”), or no flow control: hardware flow control up to 9600 bps, software or
no flow control up to 115,200 bps. The ServSwitch Multi’s Serial Control Cards support user-configurable
RS-232 connections from 1200 to 19,200 bps using 7 or 8 data bits; even, odd, or no parity; 1 or 2 stop bits;
and hardware, software, or no flow control.

2.5 Safety Precautions
To avoid potential video or keyboard problems with the ServSwitch Multi, take these precautions:
• If the site has 3-phase AC power, make sure that each ServSwitch Multi and all of the computers and
monitors attached to it are on the same phase. For best results, they should be on the same circuit.
• Use adapter cables supplied by Black Box only.
To avoid potentially fatal shock and possible damage to equipment, take these precautions as well:
• Do not use 2-wire extension cords with the ServSwitch Multi.
• Test the AC outlets that the monitors and computers are plugged into for proper polarity and grounding.
• Plug the ServSwitch Multi and all monitors and computers into grounded outlets only. If you are plugging
the Switch and any attached equipment into a backup power supply (BPS) or uninterruptible power supply
(UPS), you should plug the Switch, monitor, and computers into the same supply if at all possible.
• With the exception of adding or removing Cards, you should power down the ServSwitch Multi and all
attached computers before you service the unit in any way. Always disconnect the power cord from the unit
when you power it down.
Note that the AC inlet is the ServSwitch Multi’s main disconnect.
All ServSwitch Multi models are rated for input voltages of 110 to 240 VAC and input frequency of 50 or
60 Hz. The ServSwitch Multi Hub (KV170RA) is rated for total load-balanced input current of 7 amps: When
only one power supply is functioning, it will provide all 7 amps, but when both supplies are working, they will
share the load. All other ServSwitch Multi models are rated for 1.6 amps.
2.6 The System and Its Components
2.6.1 THE COMPLETE SERVSWITCH MULTI PACKAGE AND OTHER COMPONENTS YOU’LL NEED
• Each ServSwitch Multi Base Unit (KV150A-R2) and ServSwitch Multi MX (KV155A) is shipped from the
factory with an embedded local-console module, a power cord, and a copy of this manual.
• Each ServSwitch Multi EXP (Expansion Chassis, KV160A-R2) and ServSwitch Multi SB (KV162RA) comes
from the factory with a power cord and a copy of this manual.
• Each ServSwitch Multi Hub (KV170RA) comes from the factory with its two power-supply modules and two
fan assemblies uninstalled. It also comes with two power cords and a copy of this manual.
If you didn’t receive everything, or if anything arrived damaged, call Black Box right away.
In addition, you’ll need other components to build a complete ServSwitch Multi system (contact Black Box
Technical Support if you’re not sure what you’ll need for your application). With the Base Unit, MX, EXP, or
SB, you’ll need some combination of:
• One or more Autosensing CPU-Interface Cards (KV2000C) and one or more 8-foot (2.4-m), 20-foot
(6.1-m), or 30-foot (9.1-m) CPU (Server) Cables to attach servers or other computers to the Switch.
CHAPTER 2: Introduction
19
• To attach user stations to the Switch, 1-foot (0.3-m), 10-foot (3-m), or 20-foot (6.1-m) User Cables attached
to additional Universal User-Interface Cards (KV2500C) or User-Interface Cards with On-Screen Display
(KV2550C-R2) as necessary—up to a maximum of:
– one into an MX whose Local Console you’re using;
– two into an MX whose Local Console you’re not using;
– three into a Base Unit whose Local Console you’re using;
– four into an EXP or into a Base Unit whose Local Console you’re not using; or
– eight into an SB.
• In a cascaded multi-Switch system, expansion cables as necessary to connect Switches to each other: KV1600
for 10-foot [3-m] regular expansion cable, KV1600100 for 100-ft. (30.5-m) regular cable, or EYN737MS-MM
for Category 5 expansion cable.
• In order to attach terminals, hubs, routers, or other serially accessed control devices to the Switch, you’ll
need one Serial Control Card (KV1609C) and four Category 5 patch cables (EVMSL05) for every four such
machines, plus a single Management Card (KV1608C-R2) and a DB9 null-modem cable (EYN257H) to
hook up a PC to manage the Serial Control Cards with.
With the Hub you’ll need:
• Several Transmit Modules (KV1701C) and Receive Modules (KV1702C), plus Category 5 expansion cables
(EYN737MS-MM) to connect the Hub to the other Switches in your system.
2.6.2 R
ACKMOUNTING THE SERVSWITCH MULTI (OPTIONAL)
The ServSwitch Multi SB and ServSwitch Multi Hub can be mounted in a standard 19" equipment rack without
any additional hardware. Just match the holes in the protruding ends of the Switch’s faceplate to an
appropriate set of matching holes on your equipment rack, then fasten the assembly to the rack using your own
screws, bolts, or cage nuts (not included).
If you want to mount a ServSwitch Multi Base Unit, you’ll need a ServSwitch Multi Rackmounting Kit
(RMK19L); to mount a ServSwitch Multi EXP, you’ll need the RMK19LE Kit. See Appendix F for instructions
on how to rackmount either of these models.
The ServSwitch Multi MX is not designed to be rackmounted.

2.6.3 DESCRIPTIONS OF THE SERVSWITCH MULTI BASE UNIT AND MX AND THEIR COMPONENTS
The front panel of a ServSwitch Multi Base Unit (KV150A-R2) or ServSwitch Multi MX (KV155A) has nine
connectors (shown in Figure 2-2), one for each of these peripheral types:
• PS/2 keyboard
• PS/2 mouse
• Serial mouse
• Macintosh (Apple Desktop Bus) mouse and keyboard
• Sun mouse and keyboard
• VGA video
• RS-232 serial-port device
• Microphone
• Speakers
You can use these connectors to attach a keyboard, monitor, and mouse (and optionally a microphone,
speakers, and serial device) to the Switch’s front panel. Any peripherals attached to the front of a Base Unit or
MX together constitute its local console (user station). Through these peripherals, you can access every
computer attached to the Switch. (However, the local console has no on-screen display.)

The front panel of the Base Unit has twelve pushbuttons labeled A through L. The front panel of the MX has
four pushbuttons labeled A through D. You can use these buttons to select the active computer for the local
console. The indicator lights (LEDs) over the pushbuttons reflect the type of activity, if any, that is taking place
on each attached computer. The alphanumeric display, located in the upper right-hand corner of the front
panel on the Base Unit only, shows which computer channel is currently selected by the local console. The local
console is the only user station affected by the pushbuttons or whose channel is indicated by the Base Unit’s
alphanumeric display. At Card consoles, which connect to the Base Units and MXs through their rear panels,
you must use either the console keyboard or an on-screen display to select computer channels. As many as one
(on the MX) or three (on the Base Unit) Card consoles can have access, as the local console does, to every
computer on that Switch. (It can be two or four Card consoles if you don’t use the local console at all.) See
Section 8.3 for details.
The first slot on the far left end of the rear panels of the ServSwitch Multi Base Unit and MX (shown in
Figure 2-3) contains the local console’s module; this slot is referred to as “channel N” on the Base Unit and
“channel E” on the MX. On the Base Unit only, there’s an “option slot” next to the local console’s module,
referred to as “channel M.” There is no front-panel LED or pushbutton associated with this slot, and it is best
used for a secondary console or an expansion card. All other slots in either unit may be configured as needed.

22
Each Base Unit and MX comes with the local console module preinstalled. You will also need at least one
Autosensing CPU-Interface Card (our product code KV2000C) for each computer you plan to attach to the
Switch, as well as one Universal User-Interface Card (KV2500C) or User-Interface Card with On-Screen Display
(KV2550C-R2) for each secondary console. The CPU-Interface Card, shown in Figure 2-4, has an HD44 female
connector as a single composite interface for all I/O to and from the attached computer. The User-Interface
Cards, also shown in Figure 2-4, have an HD62 female connector as a single composite interface for all I/O to
and from the attached user station.
Figure 2-4. The ServSwitch Multi’s Interface Cards.
You’ll run an 8-foot (2.4-m), 20-foot (6.1-m), or 30-foot (9.1-m) Server Cable (shown in Figure 2-5) from the
CPU-Interface Card to the attached computer. You’ll run a 1-foot (0.3-m), 10-foot (3-m), or 20-foot (6.1-m)
User Cable (shown in Figure 2-6) from the User-Interface Card to the attached user station. Both Server and
User Cables are available with or without audio and serial components.

Besides the regular interfaces, if you’re attaching serially accessed control devices such as terminals, hubs,
bridges, or routers, you’ll need a Management Card (KV1608C-R2) and one or more Serial Control Cards
(KV1609C); see Chapter 5.

2.6.4 DESCRIPTIONS OF THE SERVSWITCH MULTI EXP AND SB AND THEIR COMPONENTS
The front panel of a ServSwitch Multi EXP (Expansion Chassis, KV160A-R2) or a ServSwitch Multi SB
(KV162RA), shown in Figure 2-7, has fourteen pairs of channel LEDs, each of which corresponds to a channel
slot in which you can install any kind of ServSwitch Multi Card. The Switch’s front panel also has POWER and
FAIL LEDs.
Figure 2-7. The front panel of an EXP or SB.
There are no pushbuttons and no display on the front panel, because EXPs and SBs do not have local consoles;
they are geared more to be subsidiary expansion units than standalone units, although with a User-Interface
Card installed they can easily perform all of the same keyboard-activated switching and command functions
that Base Units and MXs can.
The rear panels of the ServSwitch Multi EXP and ServSwitch Multi SB look identical to that of the Base Unit
(shown in Figure 2-3 in Section 2.6.3). However, instead of their leftmost slot containing the local module and
their next-to-leftmost slot having no corresponding front-panel indicator, all fourteen of the EXP’s and SB’s
slots are empty, and all of them have a corresponding pair of LEDs on the front panel.
You will need at least one Autosensing CPU-Interface Card (product code KV2000C) for each computer you
plan to attach to the EXP or SB, as well as one Universal User-Interface Card (KV2500C) or User-Interface Card
with On-Screen Display (KV2550C-R2) for each console. These cards and their cables are described in Section
2.6.3 and are shown in Figures 2-4 through 2-6 on the previous page. You will also need at least one regular
Expansion Transmit Card (our product code KV1601C) or CAT5 Expansion Transmit Card (KV1603C), shown
in Figure 2-8 on the next page, if you want consoles on another ServSwitch Multi unit to be able to access
computers on the EXP. And you will need at least one Expansion Receive Card (KV1602C) or CAT5 Expansion
Receive Card (KV1604C), also shown in Figure 2-8, if you want consoles on the EXP to be able to access
computers attached to other ServSwitch Multis. To connect serially accessed control devices such as terminals
and routers, you’ll need a Management Card (KV1608C-R2) and one or more Serial Control Cards (KV1609C);
see Chapter 5.

Figure 2-8. The ServSwitch Multi’s Expansion Cards.
Each regular Expansion Card has two HD26 ports on it (male on the Transmit Card, female on the Receive
Card); each of these is an endpoint for an independent expansion link. For example, if you run cables from
both of the ports on a Transmit Card to the corresponding ports on a Receive Card in another unit, two
different user stations on the other unit will be able to access different computers on the Transmit Card’s unit
at the same time. Alternatively, you can run a cable from each of the ports on a Transmit Card to a matching
port on two different Receive Cards, even if they are installed in different ServSwitch Multi units.

Instead of single connectors, the two ports on CAT5 Expansion Cards consist of three RJ-45 sockets each,
because three 4-pair cables are required to carry all of the signals necessary for expansion. The ports of the
regular Cards and the CAT5 Cards are shown in Figures 2-9 and 2-10; the pairing of the CAT5 RJ-45 connectors
is shown in Figure 2-11.

If you are using regular Expansion Transmit and Receive Cards, you will run a regular Expansion Cable
(shown in Figure 2-12) between a Transmit/Receive Card pair. This cable is available in stock lengths of 10 feet
(3 m, product code KV1600), 25 feet (7.6 m, KV160025), 50 feet (15.2 m, KV160050), and 100 feet (30.5 m,
KV160100). If you are using CAT5 Expansion Transmit and Receive Cards, you will run three four-pair, straightthrough-pinned, solid-conductor CAT5 twisted-pair cables (product code EYN737MS-MM, shown in
Figure 2-13) between a Transmit/Receive Card pair. This CAT5 cable is available in stock lengths of 10 feet
(3 m), 50 feet (15.2 m), 100 feet (30.5 m), or 250 feet (76.2 m), or you can order it in custom lengths.

2.6.5 DESCRIPTION OF THE SERVSWITCH MULTI HUB AND ITS COMPONENTS
The ServSwitch Multi Hub (KV170RA) is a cube that fits in 9U (15.75", 40 cm) of vertical rack space. Internally,
it will contain two power supplies and two fan assemblies (for redundancy) once you install them—they’re
shipped uninstalled to lessen the chance that they might be damaged in transit. The most prominent features
of the Hub’s front panel, as shown in Figure 2-14, are a 4-x-20-character LCD panel and four associated buttons
with which you can control and configure the Hub through an internal menu system. The Hub’s front panel
also has POWER and FAIL LEDs, as well as an RJ-45 serial port that currently has no function but might be
enabled with future firmware upgrades. The front panel is controlled by a special internal Front-Panel Element.
The Hub’s nine plug-in Module slots are “channel A” through “channel I.” For Flash-upgrading purposes only,
the Front-Panel Element is “channel J”; that channel can’t be selected and is not recognized for any other
purpose.
Figure 2-14. The front panel of a Hub.
The Hub isn’t like the other ServSwitch Multi models. No computers or user-station consoles can be directly
attached to it. It’s not designed to accept Interface Cards, regular Expansion Cards, or any other type of Card
that the other models support. Instead, it functions as a central housing for as many as nine Transmit or
Receive Modules (KV1701C or KV1702C respectively), which each channel up to 16 sets of keyboard, monitor,
and mouse signals between cascaded ServSwitch Multi units. You’ll run two CAT5 cables from the two ports of a
CAT5 Expansion Card in some other ServSwitch Multi model to two of the ports on one of the Hub’s Modules.
This centralized distribution through the Hub makes it possible to assemble very large KVM-switching systems
using fewer Expansion Cards, fewer cables, and often fewer Switch units. For more information, see Chapter 7.

User Cables, and Console Devices
IMPORTANT NOTE
If you are installing a cascaded ServSwitch Multi system, you should make sure your
Expansion Cards and Cables are installed properly before you begin installing other
types of Cards or attaching devices to the system. Refer to Chapter 6 and (if your
cascaded system includes any ServSwitch Multi Hubs) Chapter 7.
3.1 Connecting Local-Console Equipment to a Base Unit or MX
As shown in Figure 3-1, the ServSwitch Multi Base Unit and ServSwitch Multi MX have a group of connectors
on their front panels to which you can directly connect (without needing extra cables) a local console (user
station). This console can include a keyboard, monitor, and mouse, as well as a serial device, speakers, and/or
microphone.
You can independently plug a single keyboard and a single mouse (each belonging to any platform the
ServSwitch supports, in any combination) into the local console. However, do not connect more than one
keyboard, monitor, or mouse to the local console. For example, you may use a Sun mouse and a Mac keyboard
at the local console at the same time, but you must not connect two keyboards or two mice to the front of the
unit simultaneously. This could cause your computers to behave unpredictably or even crash.
The local console operates as if it were connected to a Universal User-Interface Card (KV2500C) rather than
a User-Interface Card with On-Screen Display (KV2550C-R2)—no on-screen menus are available.

3.2 Installing User-Interface Cards in a ServSwitch Multi
To install a Universal User-Interface Card (“UUIC” for short, our product code KV2500C) or User-Interface
Card with On-Screen Display (“UICD” for short, our product code KV2550C-R2) in a ServSwitch Multi Base
Unit, MX, EXP, or SB, take these steps:
1. Position the ServSwitch Multi so that its rear panel is facing you, as shown in Figure 3-3 on the next page.
Choose an available slot. In most cases, any slot that is covered with a blank (connectorless) panel will be
available. However, note that on the Base Unit and MX, the local-console module on the far left end of the
Switch’s rear panel is covered by a blank panel but is not an available slot; no ServSwitch Multi Card of any
type can be installed in that slot. Remember that the option slot (the slot just to the right of the localconsole module, which has no corresponding front-panel LED or pushbutton) is an available slot and
should preferably host a User-Interface Card, Expansion Card, etc., rather than a CPU-Interface Card.
2. Once you’ve chosen the slot, write down the letter of the corresponding channel in the “Channe Letterl”
field of this Card’s record in a copy of the User-Interface Cards pages of the System-Configuration Chart
(see Appendix A). At this time you should also write down what appears on the Card’s label (just to the
right of the HD62 connector if you look at the connector from the rear) in the Chart’s “Card-Label
Information” field, and (if the ServSwitch Multi unit is part of a cascaded system) you should write down
the Switch’s address in the “Switch Address” field as well.
3. Remove the panel covering the available slot by unscrewing the two Phillips-head screws that hold it in
place. (Save these screws; you’ll be replacing them momentarily.)
4. If you look into the open slot on the Switch, you will see “guide tracks” that the top and bottom of the Card
should slide along when you install it. Slide new User-Interface Card gently into the slot along these tracks,
until the Card’s HD62 connector lines up flush with the back of the unit, as shown in Figure 3-2.
Figure 3-2. Inserting a User-Interface Card in the Switch.
5. Secure the Card in the Switch with the screws you removed in step 3. Retighten the screws completely, but
do not overtighten them.
Repeat the above procedure for every User-Interface Card in your system.
The UUIC and the UICD share the same basic features, but the UICD has a set of on-screen display features
that the UUIC lacks. For descriptions of these features and how to use them, see Chapter 9.
