Hot Plug
The GFC 1716A supports “Hot Plug“ function for easy addition or removal of PCs. The user can
arrange or maintain PCs as follows:
c. A PC can be disconnected and reconnected to the same or different port of the KVM unit
without having to power it off as long as it is not the Daisy-chain port or pass through port.
d. The pass through port PC (i.e. The pass through port means the console port is connected

N
OTICE
Some O.S. (Operation Systems) like SCO Unix are unable to support “ Hot Plug ”
function. If you apply “Hot Plug” to this kind of O.S., it will cause unpredictable
behavior or shut down the PC. Before attempting to use “ Hot Plug ” , please make
sure your O.S. and software driver supports the “Hot Plug” function.
1. Ensure that all cables are well seated. Label all of cables with the number for each
respective computer to avoid confusion.
2. The recommended VGA cable distance is 5 meters maximum without ghosting and
degradation. Normally, the cable length is based on driver capacity of your VGA card. If you
need longer VGA cable, please use VGA extender (Model No. VGA-100, MAX. 100 feet ) to
accomplish your applications.
3. The recommended PS2 cable distance is 5 meters maximum. Normally, the cable length is
based on driver capacity of your motherboard PS2 port. If you need longer PS2 cable,
please use PS2 extender ( Model No. PS2-100, MAX. 100 feet ) to accomplish your
applications.
4. The Power Jack polarity is center positive and the power adapter need be DC12V, 1A or
DC9V, 1A.
5. Don’t press any keys on the keyboard while the selected computer is booting up. Otherwise,
it might cause the keyboard error or keyboard is not detected at PC side.
6. The computer boot up fine, but keyboard doesn’t work

z Try a different keyboard, but use only 101, 102 or 104-key keyboard.
7. The Mouse is not detected during PC boot up.
z Make sure the mouse works when directly plugged into the computer.
z Make sure the mouse is a true PS/2 mouse. A combo mouse will work just as long as it is
set for PS/2 mode with the correct adapter. Try a different mouse.
z Avoiding moving the mouse or pressing the mouse buttons when switching ports.
z Avoiding switching ports during shutting down the PC process.
z When you switch one PC port to another PC port, the best scan time setting need to be set
to 5 sec. or more. Normally, the VGA monitor change one resolution mode to another will
take one or two seconds. So, the scan time is not recommended to below 5 seconds.
8. The power switch is off, but the switch still works fine or power adapter is unplugged from the
switch, but the switch still works fine.
GFC 1716A unit draws the power source from power adapter and all PC’s PS2 port. Some
PC’s PS2 port can support enough power for the switch, but some PC’s PS2 port ( like
laptop, notebook computer…etc.) is unable to supply enough power for the switch. In order
to make sure the system can work steadily, please do not set power switch to off state or
remove the power adapter from the switch.
