Introduction
This Rack Mountable USB KVM Switch supports high resolution video applications (up
to 1920x1440 pixels supported) and audio switching between connected computers,
and provides an integrated USB 2.0 hub that lets the selected computer have access
shared high speed USB peripherals.
Providing control of up to four computers from a single USB keyboard and mouse
peripheral set, the switch features a sturdy all metal chassis and can be rackmounted
in a server rack/cabinet using an optional Rackmount Bracket kit (SV431RACK) -
minimizing clutter and saving space.

Installation
PC BIOS Notice: The following BIOS setup changes are necessary for PC users but are
not required for Mac users:
1. In STANDARD CMOS, set HALT ON ERROR to ALL BUT KEYBOARD.
2. In PNP AND PCI SETUP, set PNP OS INSTALLED to YES and set the USB IRQ
to ENABLED.
Please Note: SV431USBAE is capable of switching between computers while
maintaining USB mouse and keyboard control. If you plan to share other peripherals
such as a CCD camera, printer or scanner, you must shut down the corresponding
driver on the computer from which KVM control is being switched.
Because port switching is equivalent to unplugging the USB cable from one computer
and plugging it in on another, some USB drivers continuously check attached USB
peripherals and do not accept plug and play functionality.
Console Connection
Before installation, please ensure that all devices and computers to be connected to
the KVM Switch have been turned o.
1. Connect the monitor that will be used to the Console VGA port on the rear panel
of SV431USBAE.
2. Connect a USB keyboard and a USB mouse to any two of the Console USB ports as
shown below:
