Disabling Mouse Acceleration on the Host Computer
NOTE: If you are using USB to connect KVM switch to the host
computer, you will not be required to adjust the mouse settings
on the host computer, as this device uses “Absolute” mode, which
eliminates any problems you may otherwise experience with mouse
synchronization or host mouse acceleration.
Many operating systems offer a feature called mouse acceleration,
allowing the user to adjust the responsiveness of the cursor on the
screen in relation to physical movements of the mouse. While this
is usually a beneficial interface enhancement, it can interfere with
the operation of the KVM switch and should be disabled on the host
computer before a remote session is attempted. Follow the instructions
below to disable mouse acceleration for the operating system installed
on the host computer.

Conguring the SVxx41HDIE
This IP KVM switch offers four distinct methods for configuring the unit
for your network. Which method will work best will depend on your level
of experience and your specific network configuration.
Web Conguration Using the On-Screen Display
Upon boot-up, including following a reset, The IP KVM switch will
display a window on the local video output, that will appear as follows:
The initial screen will display the IP address assigned by your existing
DHCP server (if present on your network). If no DHCP server is
detected, a factory assigned IP address will be displayed in its place

7
(10.0.0.15 by default). Please make note of the assigned IP address,
as you will need to enter it into your web browser to access the Web
Interface.
If static IP addresses are assigned, you will likely need to change the
Net Mask, IP Address and other details, prior to connecting via your
Web browser. If this is the case, connect a local keyboard (USB or
PS/2) and press the Enter key. In order to proceed, you will require an
administrative username and password. By default, the username and
password are admin. You will be given the opportunity to change the
password (recommended) once the configuration is complete.
Alternatively, you may press the Setup button on the front panel, and
you will not be asked to enter the admin password if you just press
Enter.
At the main OSD menu (pictured below), you will be given several
basic setup options. To configure the IP KVM switch to your required
network settings, use the Network Setup Wizard. To select from the
menus provided, use the arrow keys on your keyboard. At any time,
you can return to the previous menu by pressing the Page Up key.
Web Conguration Using DHCP
This method requires that your network implement DHCP (Dynamic
Host Configuration Protocol), usually on a server or network access
device such as a router that dynamically allows devices to join the
network without pre-configuration. It also assumes that you will have
easy access to your network’s DHCP log, since you will need to know

8
the IP address of the unit to complete the configuration over your Web
browser. (If you are unsure of how to access your network’s DHCP log,
contact your System Administrator for details.) If the unit is powered
on and connected to the network via LAN port on the rear panel, it will
automatically attempt to lease an IP address using DHCP. Before you
can begin the configuration process, you will need to access the DHCP
log from your file server or other device that acts as the DHCP server
on the network. A simple DHCP log looks similar to the following:
The information displayed for your own network may vary significantly
from the data displayed in the image, but should supply (at minimum)
three essential details: IP address, MAC address, and device (or
machine) name for the computers and other devices connected to your
network. The values for the IP KVM switch tested above are as follows:
IP Address: 192.168.22.4
MAC Address: 00-0E-C5-00-08-1A
Device Name: (none)
The easiest way to identify your IP KVM switch on the network is
by its MAC address, a unique hardware identifier that is specific to
your unit. The MAC address of the unit can be found using the OSD
setup screen. Write down this number and keep it for future reference.
Once you locate the MAC address of your unit in the DHCP log,
you can match it to its leased IP address and proceed with the Web
configuration.
NOTE: Once you have located the IP address of the IP KVM switch
and wish to proceed with the Web configuration, do not power off the
unit or your DHCP server, since the Server Remote Control might
lease a different IP address. Should this happen, reexamine the DHCP
log to verify the IP address again.

9
Web Conguration Using Static IP
Since some networks rely on static IP addresses (every device has a
pre-configured IP address that does not change), the DHCP access
method described above is not applicable in those situations.
To access the Web configuration for this product, you will need
to configure the workstation you are using to the same subnet
(255.255.255.0) and also assign it a valid IP address (i.e.
192.168.1.100). For details on how to change the IP address of your
computer (if necessary), consult your documentation or System
Administrator for assistance.
NOTE: It is advisable to verify whether another device on your network
is using the same IP address as the IP KVM switch before connecting
it to the network, to avoid a conflict. Should an IP address conflict occur
with another device on the network, power off the conflicting device or
assign it another IP address before continuing the installation.
NOTE: Not all IP addresses are valid for a given subnet. If you are
required to change your subnet (and therefore IP address) to configure
the unit, be sure the IP address you choose is within the allowable
range for the 255.255.255.0 subnet.
Once your computer is configured to the same subnet as the IP KVM
switch, you can use the IP address 192.168.1.123 to access the Web
configuration system.

10
Terminal Conguration Using a Serial Cable
Configuring the IP KVM switch using a serial cable is the best choice
if you need to preconfigure the unit before attaching it to a network,
(i.e. when sending to a branch office, customer site, etc). In general,
the Web configuration is preferable because of its intuitive interface
and the fact that you do not have to be within close physical proximity
to perform the configuration. However, if you wish to use the serial
cable method to configure the IP KVM switch, you can use any typical
communication software package (UNIX: tip, cu, kermit, minicom;
Windows: HyperTerminal, kermit).
You can use the serial port on the SVxx41HDIE to access the terminal
configuration tool; to do so, you will require a null modem serial cable.
Connect a female end of a serial cable to the serial port used for
serial access on the host computer. Connect the opposite end to the
SVxx41HDIE. Configure the terminal software with “8N1” settings:
Connection speed: 115200 bps
No. of bits: 8
Parity: None
Stop bits: 1
*sample HyperTerminal configuration

11
Using the Web Interface
The Web interface is the most intuitive way to configure the IP KVM
switch. Offering a Java-based VNC client that can be used to control
the host computer from a remote location, as well as support for
any industry-standard HTML Web browser. You can access the Web
interface by opening your Web browser and entering the IP address of
the IP KVM switch you wish to access/configure. The IP address will
be either a) the address assigned by your DHCP server as identified in
the previous section, or b) 192.168.1.123 if your network uses static IP
addressing.
The Login Screen
Before you can access the Web configuration interface, you must enter
a user name and password. The default username and password as
shipped from the factory is username admin, with a password of admin.
NOTE: Before the login screen appears, your Web browser may display
a warning about an invalid security certificate. This does not affect the
security of your data in any way. Whenever you are prompted about
a certificate security problem by your browser or the Java VNC client,
always choose the option to continue. For more information, please
consult the section entitled About Security Certificate Warnings.

14
The Admin functions allow you to access all of the features you will
need to perform an initial configuration of the IP KVM switch.
Dynamic Host Configuration Protocol (DHCP)
Automatic network configuration using DHCP is: Enabled/Disabled.
This feature applies only to the LAN port on the rear panel, and is
enabled by default. When enabled, the unit will automatically configure
itself with an IP address when a DHCP server is present. When
disabled, the LAN port will use the values assigned to it on the IP
Addresses and Routing table below.
IP Addresses and Routing
This table allows you to assign IP information for the LAN port. If
you are using DHCP, the values for the LAN port will be filled in
automatically and any changes made will not affect the setup.
Domain Name Server (optional)
This section allows you to specify DNS servers and the default DNS
domain suffix in use on the network. If DHCP is enabled, some of these
values may be supplied automatically.
Clicking the Commit button applies any changes made on this page,
but leaves the old settings active until the next time the unit restarts.
Clicking Make changes effective now applies the changes and restarts

15
the IP KVM switch so the new settings take effect immediately.
Ethernet Address (MAC Address)
This is the Ethernet hardware address of this unit’s LAN port. It is set
at the factory and cannot be changed. You may need this number to
configure your DHCP server.
This menu will allow you to add accounts other than admin to the
system. These accounts will not have the authority to change settings,
but can access the Web interface and log into the VNC console.
Selecting Delete permanently removes the user from the system. If
you enter values for a user that does not already exist under Edit User
Details, the system will create that user for you when you click Record
changes. If the user already exists, you will change the password for
that user.
Machine Name
This is a name that is used to uniquely identify this machine.You might
want to create a DNS entry that matches this name. The name is
provided as the Client Name for the DHCP server. It is also shown at
the top of each page in the web browser interface and is the “desktop
name” for VNC clients.
Other identification details
These values are for information purposes. They are visible from the
VNC client and via SNMP (if enabled).
Location
This string is sent as the system.sysLocation value over SNMP. It
should describe the location of this system.
Contact Name
This string is sent as the system.sysContact value over SNMP. It
should describe who to contact regarding this machine. Typically it
includes an email address.

16
Network Address
This value is not used in our configuration, but is meant to store a user-
defined value that identifies the controlled machine on the network. The
official DNS name of the controlled machine is a obvious value to put
here, but you may use it for any purpose.
Description
A user-defined description for the controlled machine.
This menu allows you to configure a number of settings, including
changing the default password for admin (recommended). Read
and consider the comments and instructions on this menu before
making any changes, as changing these features could make the unit
inaccessible through Web configuration (i.e. due to firewall filtering).
Note that any password changes you make will have to be entered in
duplicate to prevent the chance for error.
The Compatibility menu offers features that may offer enhanced
functionality with certain KVM and power products, such as StarTech.
com’s Remote Power Switch (PCM8155HNA). These can be left at
their default values if you are not connecting the unit to a KVM or
power management device.
The SNMP menu allows you to configure the IP KVM switch so it can
be recognized and managed using industry-standard Simple Network
Management Protocol software.
The RADIUS server requires the IP address, the UDP port number
(1812 - default or 1645) and the shared secret. The shared secret
is used to encrypt communications and corresponds to a shared
password for the RADIUS server and the client machine. Two additional
servers may be defined for backup purposes. Each server will be tried
in order, using the indicated number of retries and timeout period,
which are configurable on the same page.
