Welcome to the ServSwitch™ Family!

Thank you for purchasing a BLACK BOX® ServSwitch Wireless KVM Extender! We
appreciate your business, and we think you’ll appreciate the many ways that your new
ServSwitch Wireless KVM Extender will save you money, time, and effort.

That’s because the ServSwitch Wireless KVM Extender is all about breaking away from the
traditional, expensive model of computer management. You know, the one-size-fits-all­even-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 us er stations , each of which can control
multiple computers? Why not multiple user stations for the same computer?

With our ServSwitch Wireless KV M Extende r product, 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 Wireless
KVM Extender that’s just right for you.

The ServSwitch Wireless KVM Extender from BLACK BOX—the one-stop answer for
all your KVM switching needs!
