THE SERVSWITCH™FAMILY

Welcome to the ServSwitch™ Family!
Thank you for purchasing a BLACK BOX® ServSwitch™ Brand PS/2 Micro Extender
model! We appreciate your business, and we think you’ll appreciate the many ways that your
enhanced keyboard/video/mouse system will save you money, time, and effort.
That’s because our 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 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!
This manual will tell you all about your new ServSwitch™ Brand PS/2 Micro Extender,
including how to install, operate, and troubleshoot it. For an introduction to the Extender, see

RADIO-FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate radio-frequency energy, and if not installed
and used properly, that is, in strict accordance with the manufacturer’s instructions, may
cause interference to radio communication. It has been tested and found to comply with the
limits for a Class A computing device in accordance with the specifications in Subpart B of
Part 15 of FCC rules, which are designed to provide reasonable protection against such
interference when the equipment is operated in a commercial environment. Operation of this

interference.
Changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.
Shielded cables must be used with this equipment to maintain compliance with radio
frequency energy emission regulations and ensure a suitably high level of immunity to
electromagnetic disturbances.
This digital apparatus does not exceed the Class A limits for radio noise emission from digital
apparatus set out in the Radio Interference Regulation of the Canadian Department of
Communications.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites
applicables aux appareils numériques de la classe A prescrites dans le Règlement sur le
brouillage radioélectrique publié par le Ministère des Communications du Canada.
