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
