SERVSELECTTM III INSTALLER/USER GUIDE
Welcome to the ServSwitch™Family!
Thank you for purchasing a BLACK BOX®ServSelect™III! We appreciate your business,
and we think you’ll appreciate the many ways that your new ServSelect III will save you
money, time, and effort.
That’s because the ServSwitch family is all about breaking away from the traditional,
expensive model of computer management. You know, the one-size-fits-all-even-if-it-
doesn’t model that says, “One computer gets one 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 multiple user stations for the same computer?
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? Does your switch have to sit solidly on a work table 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. Product Overview
2.1 Features and Benefits
The ServSelect® III family of switches integrate field-proven analog keyboard, video and
mouse (KVM) switching technology with advanced cable management, flexible access for
two simultaneous users and a patented, easy-to-use interface. This ServSelect III family of
KVM switches conveniently supports all major server platforms, and features powerful
on-screen management for easy system configuration and server selection.
Server Access Module
A benefit of the ServSelect III switches are the Server Access Modules (SAM). The SAM
with CAT 5 design dramatically reduces cable clutter, while providing optimal resolution
and video settings. The built-in memory of the SAM simplifies configuration by assigning
and retaining unique server names and Electronic ID (EID) numbers for each attached
server. The SAM is powered directly from the server and provides Keep Alive
functionality even if the ServSelect III is not powered.
Each ServSelect III has either eight or 16 server ports for connecting SAMs. Utilizing a
SAM, you can attach additional switches to expand your ServSelect III switching system.
This flexibility allows you to add capacity as your data center grows. Reduced cost
ServSelect III cables are also available.
Multiplatform support
The SAMs are available with the ServSelect III support PS/2, Sun™, USB and serial
server environments. Using the On Screen Display (OSD) in conjunction with these
modules allows you to switch easily across platforms.
Two-User Share Mode
The ServSelect III switches feature a Share Mode function that allows two users to
gain access to a primary server. The user configurable time-out feature allows
you to determine the amount of time (up to 600 seconds) for the target to remain
idle before the other user can take control of the target.
On Screen Display
ServSelect III uses an OSD, which features intuitive menus to configure your switching
system and select computers. Computers can be identified by unique name, EID or port
number, allowing you to assign unique server names.
Security
The OSD allows you to protect your system with a screen saver password. After a user-
defined time, the screen saver mode engages and access is prohibited until the appropriate
password is entered to reactivate the system.
Operation modes
The OSD provides convenient operation modes for easy system administration of the
ServSelect III family of switches. These modes (broadcast, scan, switch and share) allow
you to manage your switching activities. Chapter 3 explains these modes in detail.

SERVSELECT III INSTALLER/USER GUIDE

Video
The ServSelect III provides optimal resolution for analog VGA, SVGA and XGA video.
Achieve resolutions of up to 1280 x 1024 with a 10 foot cable and up to 800 x 600 with a
50 foot cable. Resolutions will vary depending upon the length of cable separating your
switch and servers.
Plug and Play
The ServSelect III also supports Display Data Channel (DDC) Plug and Play, which
automates configuration of the monitor and is compliant with the VESA DDC2B standard.
Flash upgradable
Upgrade your firmware at any time through a simple update utility to ensure that your
ServSelect III switching system is always running the most current version available. Both
the ServSelect III and the SAMs are Flash upgradable. See Appendix A for more
information.
NOTE:
ServSelect III cables are not firmware upgradable.
Cascading expansion
The ServSelect III provides support for up to 16 directly attached servers and can
conveniently scale to support more. You can expand your system using cascadable
BLACK BOX products such as other ServSelect switches. This extra “cascade” of units
allows you to attach up to 256 servers in one system. See Chapter 3 for more information.
NOTE:
KV21008A and KV22008A only support eight directly attached servers.
ServSelect III cables
The ServSelect III also features ServSelect III cables designed to provide the same ease of
use as the SAM. Available in three different lengths, ServSelect III cables are RJ45 style
cables that provide a reduced cost alternative to SAMs. ServSelect III cables support PS/2
and USB connectivity. ServSelect III cables are not upgradeable.

2.2 Safety Precautions
To avoid potential video and/or keyboard problems when using BLACK BOX products:
•Ιf the building has 3-phase AC power, ensure that the computers and monitors are on
the same phase. For best results, they should be on the same circuit.
• Use only BLACK BOX-supplied cable to connect computers and KVM switches.
To avoid potentially fatal shock hazard and possible damage to equipment, please observe
the following precautions:
• Do not use a 2-wire extension cord in any BLACK BOX product configuration.
• Test AC outlets at the computer and monitor for proper polarity
and grounding.
• Use only with grounded outlets at both the computer and monitor. When using a
backup Uninterruptible Power Supply (UPS), power the computer, the monitor and
the ServSelect III off the supply.

Rackmount safety considerations
• Elevated Ambient Temperature: If installed in a closed rack assembly, the operation
temperature of the rack environment may be greater than room ambient. Use care not
to exceed the rated maximum ambient temperature of the unit.
• Reduced Air Flow: Installation of the equipment in a rack should be such that the
amount of airflow required for safe operation of the equipment is not compromised.
• Mechanical Loading: Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
• Circuit Overloading: Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of circuits might have
on overcurrent protection and supply wiring. Consider equipment nameplate ratings
for maximum current.
• Reliable Earthing: Reliable earthing of rackmounted equipment should be
maintained. Pay particular attention to supply connections other than direct
connections to the branch circuit (for example, use of power strips).

3.5 Cascading ServSelect III Switches
You can cascade multiple ServSelect III switches to enable one or two users to connect to
as many as 256 servers. In a cascaded system, each user port on the main ServSelect III
switch will connect to the server port on each cascaded ServSelect III switch. Each
cascaded switch can then be connected to a server with an SAM or ServSelect III cable.
The example shown in Figure 2.3 shows one ServSelect III switch cascaded under the
main switch, enabling the connection of up to 15 primary servers and 16 secondary
servers. Using this configuration, you could cascade 16 ServSelect III switches under the
main switch, enabling the connection of up to 256 servers. Only one level of tiering is
supported in this type of configuration, which means you cannot cascade any additional
legacy switches or another ServSelect III switch.
In this configuration, the local port OSD interface is disabled in switches cascaded below
the main ServSelect III switch.
To cascade multiple ServSelect III switches:
1. Connect the cascaded ServSelect III switch to each server as described in the previ-
ous Installing the ServSelect III Switch section.
2. Connect the local peripherals to analog user A and/or B of the main switch as
described in To connect local peripherals.
3. Attach one end of the CAT 5 cabling that will run between your main and cascaded
ServSelect III switch to the RJ45 server port on the cascaded ServSelect III switch.
4. Attach the other end of the CAT 5 cable to one of the RJ45 user ports on the main
ServSelect III switch.

CHAPTER 3: INSTALLATION
