CHAPTER 2: Introduction
Thank you for choosing a KVM Switch. Designed with your needs in mind,
and for plug-and-play operation in particular, your new switch will simplify
your job by helping you organize your multiple-computer applications.
Because the KVM Switch lets you use a single keyboard, monitor, and
mouse to access a number of computers, you can significantly reduce
your equipment overhead and end keyboard and monitor clutter.
This chapter describes everything that comes with the switch, the external
and operating features of the switch, and the cabling you’ll need for the switch.
2.1 The Complete Package
Your KVM Switch package includes the KVM Switch unit and this manual.
If you didn’t receive everything, contact Black Box.
2.2 Operating Features
Some of the useful features of your KVM Switch:
• Access two or four CPUs with one keyboard, monitor, and mouse.
• Available in six different models for three different platforms:
For IBM®AT®or PS/2®PCs or compatibles: SW730A has two ports,
SW731A has four.
For Apple®Macintosh®computers: SW732A has two ports, SW733A
has four.
For Sun®workstations: SW734A has two ports, SW735A has four.
• PC and Sun models only: Emulates keyboard and mouse functions
for automatic boot-up.
• With front-panel pushbuttons, you can switch directly to your desired
CPU without cycling through other CPUs (as you would with a rotary-
knob type of switch).
• Has its own printed-circuit board for maximum reliability.
• Supports all video resolutions up to 1280x1024 noninterlaced
(Sun models) or 1024 x 768 noninterlaced (PC and Mac®models).
