THE SERVSWITCH™ FAMILY
Welcome to the ServSwitch
TM
Family!
Thank you for purchasing a BLACK BOX®ServSwitch™Brand KVM 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-sizefits-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!
