Installation
This section will guide you through the hardware installation of your SV831DI or SV1631DI. Please read
through this section carefully and complete each step in the order listed.

6
1. Make sure all computers and devices are powered off.
2. Attach each of your managed computers to your StarView KVM switch using the ultra-thin 3-in-1
KVM cables. Use the 3-in-1 cables to connect one of the PC ports on the back of the switch to the
computer's keyboard, mouse, and video ports. For information on cascading your KVM, see “Cascade
Configuration.”
3. Attach your KVM switch to the SV1110IPEXT with the integrated KVM cable. Plug the male video
connector (blue) into the Console monitor port on the KVM switch and plug the female end of the
video cable (blue) into the Video (In) port on the back of the SV1110IPEXT. Plug the keyboard
(purple) and mouse (green) connectors into the KVM switch's Console keyboard and mouse ports and
plug the PS/2 connectors on the opposite end to the Host Keyboard and Host Mouse ports on the rear
panel of the SV1110IPEXT.
4. Plug a keyboard and mouse into the Local Keyboard and Local Mouse ports on the front of the
SV1110IPEXT.
5. Attach your monitor by connecting the monitor video cable to the Video (Out) port on the front of the
SV1110IPEXT.
6. Using standard Ethernet patch cables, connect the LAN and/or WAN ports on the back of the
SV1110IPEXT to your network (usually a router, hub/switch, or wall outlet).
NOTE: The LAN and WAN ports are factory-configured with different settings that can affect the
configuration method you wish to use with the SV1110IPEXT. See “Configuration Methods
Explained” on page 8 for more details.
7. Power on your KVM Control Over IP Console, your KVM Switch, and your computers.
IMPORTANT: If you connected the optional WAN connector on the SV1110IPEXT to your network, you
must also connect the optional second AC/DC adapter to the unit. This provides a load-balancing feature
between the two power sources and allows the unit to function if one adapter fails.
NOTE: If you are using cables other than those provided in the package or branded by StarTech.com,
ensure that the cables are of high quality and use the minimum possible distance necessary. Low quality or
excessively long (particularly video) cables between the host computer and the SV1110IPEXT could
degrade performance.
IMPORTANT: The SV1110IPEXT is convection-cooled. Ensure the vents on both sides are
unobstructed.

Configuration Methods Explained
The SV1110IPEXT offers three distinct methods for configuring the unit for your network. The method
that will work best for you will depend on your level of experience and your specific network
configuration.
Accessing Web Configuration 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 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 the 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
above 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
SV1110IPEXT 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 SV1110IPEXT 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 on a white sticker on the
bottom of the SV1110IPEXT. 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.

9
NOTE: Once you have located the IP address of the SV1110IPEXT and wish to proceed with the Web
configuration, do not power off the unit or your DHCP server, since the KVM might lease a different IP
address. Should this happen, re-examine the DHCP log to verify the IP address again.
NOTE: DCHP functionality is not affected if you also connected the WAN port on the SV1100IPEXT to
your network (see below).
Accessing Web Configuration 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 accommodate
this type of installation, the WAN port on the rear panel of the SV1110IPEXT is factory-configured with
its own IP address.
NOTE: If you connected the LAN port on the rear panel of the unit to your network but did not connect the
WAN port, you must disconnect the Ethernet cable from the LAN port and move it to the WAN port
before attempting a static IP installation. (If desired, you can return the cable to the LAN port if you
configure it with a static IP address during the configuration process.) If you have connected both the LAN
and WAN ports on the KVM to your network, you may proceed with a static IP Web configuration.
The following are the default values for the WAN port, configured at the factory:
IP Address: 192.168.1.123
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.254
Broadcast: 192.168.1.255
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. 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 SV1110IPEXT 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 SV1110IPEXT, you can use the IP address
192.168.1.123 to access the Web configuration system.
Accessing Terminal Configuration Using a Serial Cable
Configuring the SV1110IPEXT using a serial cable is the best choice if you need to pre-configure 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 far preferable because of its intuitive interface and the fact that you do not have to be
within close physical proximity to do the configuration. However, if you wish to use the serial cable
method to configure the SV1110IPEXT, you can use any typical communication software package (UNIX:
tip, cu, kermit, minicom; Windows: HyperTerminal, kermit).
Using a DB9 male-to-female (straight-through, not null-modem) connect the end of the cable with the male
connector to the DCE Serial port on the rear panel of the SV1110IPEXT. Connect the end with the female

10
connector to the serial port on the computer you are using to configure the unit. Configure the terminal
software with “8N1” settings:
Connection speed: 115200 bps
No. of bits: 8
Parity: None
Stop bits: 1
Configuring the SV1110IPEXT
Using the Web Interface
The Web interface is the most intuitive way to configure the SV1110IPEXT. It also offers a Java-based
VNC client that you can use to control the host computer from a remote location. The SV1110IPEXT
supports any industry-standard HTML Web browser. You can access the Web interface by opening your
Web browser and entering the IP address of the SV1110IPEXT 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
Appendix A, “About Security
Certificate Warnings”.

The Home Screen
The Home screen serves two functions. First, it is a place to check the status of the SV1110IPEXT, view
essential system information, and
capture screen shots from the host
computer. Second, it is where you
can start the integrated Java VNC
client to interact with the host
computer by clicking on the large
screen shot or choosing one of the
VNC client links.
The Admin/Setup Screen
This is the menu that will allow you
to access all the features you will
need to perform an initial
configuration of the SV1110IPEXT.
Each of the options is explained in
detail here.
Network Configuration (IP address. Netmask, etc).
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.
Current DHCP Lease
Information
This box provides detailed information about the IP lease that the unit has obtained from the DHCP server.
IP Addresses and Routing
This table allows you to assign IP
information for the LAN and WAN
ports separately. 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. If Ethernet Bridging is
enabled (see below) the WAN port

12
will use the same settings as the LAN
port, and any changes will not affect the
setup for that port. Adjusting the setting
for the WAN port allows you greater
control over how the SV1110IPEXT is
configured for access from outside the
local network, particularly if a firewall
or proxy is in use.
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.
Commit Network Changes
Clicking the Commit button applies any
changes made on the page to the
configuration, but leaves the old settings
active until the next time the unit restarts. Clicking Make changes effective now applies the changes and
restarts the SV1110IPEXT so the new settings take effect immediately.
Ethernet Bridging
When Ethernet bridging is enabled, the two Ethernet ports are virtually connected inside the
SV1110IPEXT. Packets arriving on either port that are not meant for it will be forwarded out to the other
port, when appropriate. IEEE-802.1d (“Spanning Tree Protocol”) is implemented to avoid broadcast storms
and to determine the topology of the network.
You may enable this feature so that the module can be inserted inline with the host it monitors. This
reduces the wiring and number of Ethernet ports required. Alternatively, you may connect both the WAN
and LAN ports to the same logical network through redundant Ethernet switches. If one switch fails, the
other will be used. When
bridging is enabled, both ports
share the same configuration
(DHCP or static IP addresses)
and the WAN port may not be
separately configured. Using
DHCP with Bridging increases
boot time, because the 802.1d
(STP) algorithm must finish
before the DHCP broadcast can
go out. To change this setting,
select either Enabled or Disabled from the drop-down menu and click Commit and Apply.
Setup compatibility with host system, external KVM, external power bar.
This menu offers features that may offer enhanced functionality with certain KVM and power products.
These can be left at their default values in many situations.
Port numbers to be used for different services.
Takes you to the Ports menu (see below).

13
SNMP agent setup and configuration.
This menu allows you to configure the SV1110IPEXT so it can be recognized and managed using industry-
standard Simple Network Management Protocol software.
Debug network setup values and routing.
Takes you to the Status menu (see below).
Security policy,
internal firewall and
master password.
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 reduce the chance of
error.
RADIUS authentication setup.
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. Remember to enable RADIUS
after configuring it. While RADIUS
authentication is enabled, the locally
defined accounts on the KVM control over IP module will not be used, except for the SSH login. However,
if a user name of the form
“name.local” is given at the RADIUS
prompt, the system will use “name”;
check the password locally, and skip
RADIUS authentication. Delete all
local accounts to avoid this behavior.
When connecting via VNC, a login
screen is generated that asks for a
RADIUS username and password.

14
User accounts: add, delete and change passwords.
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 in 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.
Firmware and flash memory management.
The firmware on the KVM control over IP is field upgradeable. To upgrade to another version, login as
admin.
Auto Self Upgrade
The KVM control over IP module
includes an innovative feature allowing
the unit to upgrade itself over the
Internet. Simply click on the button
labeled Upgrade to Latest and the
module will go out to the Internet and
download the latest version of the system
firmware and then install it. If the
module cannot access the Internet
directly (perhaps due to a web proxy or
other firewalls), then a page will be
shown that causes your browser to
download the required file. Save this file
to disk and then upload it as described in
the next section, Manual Upload. The
main FPGA is upgraded separately, and
has its own Get latest button. This file is
unique for each unit, so it must be done
in this manner.
If you have multiple units to upgrade, you may choose the Get latest version button that will not attempt to
upgrade the unit directly, but will instead fetch the required file. This file can be uploaded to multiple units
manually.
Manual Upload
Enter the name of the firmware file that you received from StarTech.com into the field provided (or use the
Browse... button). Press Start Upload and wait until a successful upload message is shown.
NOTE: Remember the following during the firmware upgrade…
•Do NOT turn off power to unit before this operation completes successfully. It may take several
minutes to write to flash memory.
•The unit will sometimes reboot as part of the upgrade procedure, depending on which system
component is upgraded. You will have to reconnect and re-login in those cases.
•Wait at least two minutes after pressing Start. Do not assume the upload did not work. There is no
status indicator bar to show the progress of the upload. The upload could simply be slow.
•Each file that is distributed upgrades a different component of the system. Therefore, be sure to apply
all files you are given as part of an upgrade. The system knows what to do with each file you give it,
and they are checked for validity before being applied.

15
Software Options Upgrade
Certain firmware features may be offered separately from the base unit, in order to reduce the initial cost
for the KVM control over IP module.
NOTE: If you wish to upgrade after the system is in operation, go to the Manage Firmware page and scroll
down to the section entitled Purchase Options.
Look for a unique code, like the following one:
4-C80C-B960-1-0
If you provide this code to the technical support department, they can give you an unlock code that will
open any feature you request. Types in the code provided, exactly, into the area provided and click
“Submit”. The new features opened by the code will be enabled immediately, but you may need to reboot
the unit to begin using certain features.
Set date and time.
Allows you to set the unit to local or Universal Coordinated Time (GMT).
Change system identification.
Provides details about this SV1110IPEXT that will be available to DHCP servers, SNMP agents,
and VNC clients. While these values do not affect the operation of the unit, they make it easier to
manage on the network.
The File Transfer Screen
The SV1110IPEXT is able to
emulate a disk driver attached
to the host via USB. Depending
on configuration, it will appear
to the host as a floppy drive
(1.44MB), an 8MB RAM disk
or a CD-ROM. The host
computer does not require any
special drivers or other
configuration. It just looks like
a new USB drive. You can
transfer files onto the virtual
disk while it is “ejected” and
then “insert” the disk so the host
can see the files. Any files the
host writes to the disk can be
retrieved once the disk is “ejected”.
Access to the files is performed through the web interface. The disk may be inserted from either the web
interface, or the Disk Control menu available via VNC. Most operating systems can “Eject” the disk once it
is inserted, but it can also be ejected from the Web or VNC.
When emulating a floppy disk or RAM disk, the data is stored in RAM on the SV1110IPEXT itself. In
order to emulate a CD-ROM disk drive, a web server is required to provide the CD-ROM image data. The
web server must be accessible to the module, which communicates with it constantly as data is needed.
Floppy mode
Choose the Format as floppy button to switch to floppy mode. Under Windows, the drive will be
identified as a “high density floppy” and will typically be assigned a drive letter of “B:”. The capacity is
limited to 1.44 megabytes in this mode. The purpose of supporting floppy mode is to permit the use of
floppy-disk images generated by other systems. For example, the flash BIOS upgrade process is performed

16
with a special floppy and is bootable. You can transfer bits from that floppy to the SV1110IPEXT (use the
upload disk image form). Now, you can boot from the special floppy. In addition, emergency repair disks
are often restricted to floppies.
RAM disk mode
Choose the Format as
ramdisk button to
switch to RAM disk
mode. This mode is
intended to facilitate
simple data transfer
between the remote user
and the host computer. It
will be recognized by
Windows as an eight
megabyte removable
disk and assigned a drive
letter. You can easily
drag and drop files up to
8MB in size to this
device. In Windows
explorer, you can choose
the “Eject” option to
make the data available
to the remote users.
Reading files from disk
On the File Transfer menu, make sure the disk is “ejected,” then choose the Browse files link. A web page
will be generated that shows the root directory on the disk. You can download files to your browser by
clicking on the file name. It is also possible to delete files and create directories using the buttons provided
on that page.
Disk Formats
When you choose the Format as... button, the disk image stored in RAM is formatted to be an empty MS-
DOS disk, with a single file called “Put files here...TXT”. The SV1110IPEXT is able to read most MS-
DOS/Windows formatted disks and presents the files via the web interface. However, disk emulation
occurs at the lowest level so that other disk formats can be used, if you have the tools needed to create and
read the disk images. At the bottom of the page are the upload and download options for the entire disk
image. Any image that is exactly 1,474,560 bytes long will be treated as a floppy. Images of other sizes are
supported up to 8MB.
CD-ROM Mode
The SV1110IPEXT does not store any data in this mode. Instead, it emulates a USB CD-ROM drive with a
disk inserted. The data from that disk must be provided by an external web server. You will need a copy of
the CD-ROM contents that you want to emulate as an ISO file. This is a byte-for-byte copy of track one
(the data track) of a data CD-ROM. The ISO file must be made available on a web server which is
accessible by the SV1110IPEXT. To switch to this mode, type in a URL pointing to the ISO image, and
click on Commit. The system will connect to the web server and test the file for access. If successful, you
will be shown a short report on the file contents, and the disk will be ready to use. Currently there is no
other way to preview or browse the contents of the CD-ROM image, except from the host.

17
CD-ROM Web Server Requirements:
•Data must be hosted on a web server that the SV1110IPEXT can access directly, preferably on the
same LAN.
•An image of a bootable CD-ROM disk can be used by the BIOS to boot an operating system.
•The image file itself may be any size, but it will typically be less than 700 megabytes. Normally this
file will be an ISO image (an ISO-9660 file system) but any disk image may be used.
•Web server must support “byte ranges”. Persistent connections are used, if available, as this greatly
improves performance. Read-only access is provided; writing is not supported.
Booting from USB Disk
If the host machine's BIOS supports USB boot devices, it is possible to boot from the emulated CD-ROM
or floppy. This allows complete operating system replacement without touching the computer.
The first step is getting a bootable disk image onto the emulated floppy or CD-ROM. For CD-ROM
images, you will need an ISO image from a disk that contains special bits to enable boot (“El Torito”
standard). Nothing special is needed when reading the ISO from a working, bootable CD-ROM. To create a
bootable floppy, you can format the emulated floppy from the target system, or read the data from a
working boot floppy. This can be done from Windows using “Disk Copy” (right click on the drive letter in
the Windows Explorer) or by using a program like “RAWRITE”.
Once you have a bootable image (CD-ROM or floppy) working on the KVM control over IP module, you
must adjust your BIOS settings to tell it to
boot from a USB device.
NOTE: You must select “USB CD-ROM” as
the boot device for the BIOS, if using a CD-
ROM image and “USB Floppy” if using a
floppy image.
BIOS and OS Vendor Support
NOTE: Up-to-date information about OS and BIOS support is listed in the on-line help page of the internal
web server.
Windows 95 or earlier: No USB support.
Windows 98: Keyboard and mouse are supported. Floppy/CD-ROM disk emulation is not supported.
Windows 2000 SP3+: Keyboard and mouse are supported. A bug in versions before Sevice Pack 2
prevents floppy/CD-ROM support from working correctly. (In particular, it appears to work, until you
attempt to transfer files bigger than 4096 bytes). Upgrade to SP3 or later for full disk emulation support.
Windows XP, Windows Server 2003: Keyboard, mouse and disk emulation are supported.
FreeBSD 4.5: Keyboard, CD-ROM tested and working; other features untested.
AMIBIOS (from American Megatends Inc): Keyboard, floppy and CD-ROM emulation work well. It is
possible to boot from virtual CD-ROM or Floppy. You must enable either the USB floppy or CD-ROM as
a boot device (under Advanced Setup) and enable “USB Function for DOS” (under Features Setup).
Award BIOS (from Phoenix Technologies): USB Keyboard works. USB booting is not implemented by
this BIOS, although it is listed in the menus.
NOTE: BIOS firmware is constantly evolving. Contact your computer or BIOS manufacturer for the latest
release of your computer’s BIOS for maximum functionality.

Status Screen
This screen displays a system security log, various system settings, and the ability to generate a copy of the
system configuration in plain text format.
Port Numbers
This table allows you to change
TCP port values for services
available on the SV1110IPEXT.
By default, they are factory-set
to common Internet values.
You may wish to enhance
security by disabling services
that you will not use with the
unit. To disable a service,
change its port number to 0.
For flexibility, both the LAN
and WAN ports can be
configured separately. When
you have made any necessary
changes, click Commit
Changes to use the settings the next time the SV1110IPEXT restarts. To force the unit to restart
immediately, click Restart Servers.

Using the Terminal Interface via Serial Port
The terminal interface you can access via the serial port permits the configuration of the basic settings of
the SV1110IPEXT. While not intended to be a substitute for the Web interface, it does allow you to
configure some of the same functions. The menu list below describes the options that can be modified
through the terminal interface:
Note that you must use the Woption to confirm any changes you make before restarting the unit or the
changes will not take effect. There is no restart option available from the command line; power the unit off
and on again manually to restart the unit in the new configuration.
