1.0 USB ServerSwitch - Introduction
The USB ServerSwitch is an intelligent KVM switch for keyboard, high-resolution
video and mouse for a 2-User by 8-server configuration. The USB ServerSwitch
(for simplicity, it may be referred to as the “USBSS”) supports individual USB
keyboards and mice. The USB ServerSwitch has full-time keyboard and mouse
emulation to each PC or server. This assures that there will be no interruptions or
interference to boot processes or other CPU activity. The video switching circuitry
is designed with state of the art video multiplexers that support high-resolution
graphics adapters with video resolutions of 1600 x 1200 pixels.

The USB ServerSwitch front panel has a built-in 24 character, 2 line backlit LCD
display. The top line displays Port data for the currently-selected server port, and
the bottom line is dedicated to real-time status monitoring. The USB ServerSwitch
can be controlled either through on-screen menus (see section 3.0) or directly
using the Up and Down buttons on the USBSS (see Section 3.3).
The USB ServerSwitch’s rear panel provides USB connections for Keyboard and
Mouse and HD15 Video for 8 Servers (Inputs), 2 USER/OUTPUT console
positions, and CONTROL and Video Cascade ports for expanded configurations
(see Section 6.0) that supports up to 64 connected servers. Also found on the back
panel is the AC power input, fuse, and Power Switch for the unit.

The USB ServerSwitch is designed for rack mounting in a conventional 19-inch
equipment rack, requiring 1RU (1.75 inches) of rack height. The unit may also be
placed on a shelf; and the included rack mounting flanges are removable. The unit
is convection cooled and does not require a fan or air conditioning.
