THE SERVSWITCH FAMILY
Welcome to the ServSwitchTM 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 relatively inexpensive 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!
