THE SERVSWITCH™FAMILY
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.
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™ Wizard unit,
including how to install, operate, and troubleshoot it. For an introduction to the
ServSwitch Wizard, see Chapter 2. The ServSwitch Wizard product codes covered
in this manual are:
