Step 3 – Power ON your system:

• Power ON the monitor: Make sure that the monitor is turned ON

prior to powering ON the KVM.

• Power ON the system: Connect all peripherals and computers to

the KVM prior to powering it up. Power ON the K VM by plugging it
to the AC wall outlet. By default, after product power-up, the active
channel will be computer #1, indicated by the applicable front panel
push button LED lit.

Note: Power ON self-test: As the product powers-up it performs a self-test
procedure. In case of self- test failure for any reason, including jammed buttons,
the produc t will be Inoperable. S elf-test failure will be ind icated by abnormal LED
behavior – for further information please refer to the KVM setup guide.

Front Panel Push-Buttons

• Following power up, the default channel is #1.

• Select any other channel by pressing the appropriate front panel
push button.

• The mouse cursor will be positioned at the center of the selected
computer display.

• The currently selected channel is indicated by the illumination of
the appropriate push-button.

Filtered USB Port (fUSB) Operation

• This product is equipped with a fUSB port which by default
accepts only USB authentication devices (smart card / biometric
readers).

• When a legitimate USB device is connected to the fUSB console
port the fUSB status LED on the front panel is illuminated with
steady GREEN.

• When a non-legitimate USB device is connected to the fUSB
console port the fUSB status LED on the front panel is illuminated
with steady RED.

HSL Mini-Matrix Quick Setup Guide

• Once switching between channels, for example from channel #1
to channel #3, the USB device which is connected to the fUSB port
is automatically switched accordingly. This is indicated by channel
#3 fUSB LED turning steady GREEN.

• When switching to a channel that has no USB fUSB connection,
the fUSB Port remains mapped to the last channel that had a fUSB
connection.

• Press the freeze USB button on the front panel to assign the fUSB
port to a specific computer. Freeze USB prevents switching the
fUSB port while the keyboard, video, mouse and audio peripherals
are switched between computers. Freeze USB is useful for various
scenarios, for instance, when a USB smart card reader must
remain mapped to a certain computer.
