Introduction
Thank you for purchasing a StarTech.com IP KVM Switch with USB Console. The
SV441DUSBI / SV841DUSBI revolutionizes remote server management by combining
our industry-leading, third generation Server Remote Control technology with a
proven Enterprise class digital KVM switch.
This IP KVM Switch empowers you to securely manage up to four or eight computers
remotely from almost anywhere using the internet or your local area network (LAN).
Unlike software solutions that require installation and work through your server’s
operating system, the IP KVM Switch gives you BIOS level control and full interaction
with your system’s boot process. Control does not come at the expense of security: SSH
tunneling, SSL encryption, RADIUS authentication, and a congurable rewall are all
included to ensure that your network stays secure. Its standardized 1U rack-mountable
metal chassis allows easy installation in your existing rack or cabinet solution.
Server Remote Control is about more than just servers. Using the Serial Remote
Interface Module (RPORT), you can interact with virtually any device that uses a
RS-232 serial terminal interface like routers, switches, environmental controls, alarm
systems, and more. You can also use StarTech.com’s 8 outlet Remote Power Module
(PCM815SHNA) to power computers and equipment on an o using an interactive
menu.

Using the Web Interface
The Web interface is the most intuitive way to congure the IP KVM Switch, oering 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/congure. The IP address will be either:
a) The address assigned by your DHCP server as identied in the Initial Setup
section, or
b) A static IP address as congured during the Initial Setup. NOTE: The default static
IP address of the IP KVM is 192.168.1.123
The Login Screen
Before you can access the Web conguration interface, you must enter a username and
password. The default username and password as shipped from the factory is ‘admin’
for the username, with a password of ‘admin’.
NOTE: Before the login screen appears, your web browser may display a warning
about an invalid security certicate. This does not aect the security of your data in any
way. Whenever you are prompted about a certicate security problem by your browser
or the Java VNC client, always choose the option to continue.

Web Interface, you will be required to re-enter your username and password.
VNC: To launch or disconnect a Virtual Network connection with the controlled
computer, click on Connect or Disconnect as appropriate.
File Transfer
The IP KVM is able to emulate a virtual USB
disk drive on any host connected using the
USB Server Interface Module (SV5USBS).
Depending on conguration, it will appear to
the host as a oppy drive (1.44MB), an 8MB
RAM Disk or a CD-ROM. The host computer
does not require any special drivers or other
conguration. You can transfer les to the
virtual disk at any time.
The IP KVM will wait until the host is not using
the disk, and add or remove the les.
When the host computer next looks at the
drive, it will notice the changes. You can read
les from the virtual disk at any time, as long
as the host is not actively writing to the disk.
All of this happens in the background, and
you may treat the virtual disk as a shared drive
without any restrictions.
• Access to the les is performed through the web interface. Contents of the root
directory are shown on the home page. You can download les as you would any
le on the web (right-click and Save target as).
• To upload a le, click Browse, select a le, and then click Upload.
• Files and directories may be deleted using the Delete button situated to their right.
When emulating a oppy disk or RAM Disk, the data is stored in RAM on the IP KVM
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 unit, which
communicates with it constantly as data is needed.
Floppy mode: Choose the Format as oppy button to switch to oppy mode. Under
Windows, the drive will be identied as a “high density oppy” 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
Instruction Manual
9
oppy mode is to permit the use of oppy-disk images generated by other systems
(e.g. the ash BIOS upgrade process is performed with a special oppy and is bootable,
emergency repair disks are often oppy-based etc.). You can transfer bits from that
oppy to the IP KVM (use the upload disk image form) and boot from the special
oppy.
CD-ROM Mode: The IP KVM 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 le. This is a byte-for-byte copy of track one (the data track) of a data
CD-ROM. The ISO le must be made available on a web server that can be accessed by
the IP KVM. 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 le for access. If
successful, you will be shown a short report on the le contents, and the disk will be
ready to use.
Please note that the only way to preview or browse the contents of the CD-ROM
image, is from the host.
CD-ROM Web Server Requirements:
• Data must be hosted on a web server that the IP KVM can access directly.
• An image of a bootable CD-ROM disk can be used by the BIOS to boot an operating
system.
• The image le itself may be any size, but it will typically be less than 700Mb.
Normally this le will be an ISO image (an ISO-9660 le system) but any disk image
may be used.
• The 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.
• CD-ROM block size must be 2048 bytes. XA-Data type tracks are not supported.
RAM Disk mode: Choose the Format as RAM Disk 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 8MB removable disk and
assigned a drive letter. You can easily drag and drop les up to 8MB in size to this
device.
Disk Formats: When you choose the Format as... button, the disk image stored in RAM
is formatted as an empty MS-DOS disk, with a single le called Put les here...TXT.
The IP KVM is able to read most MS-DOS/Windows formatted disks and presents the
les via the Web interface. However, disk emulation occurs at the lowest level, so 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 oppy.
Images of other sizes are supported up to 8MB.
Instruction Manual
10
Booting from USB Disk:
If the host computer’s BIOS supports USB boot devices, it is possible to boot from
the emulated CD-ROM or oppy - allowing complete operating system replacement
without any on-site intervention.
The rst step is getting a bootable disk image onto the emulated oppy or CD-ROM.
For CD-ROM images, you will need an .ISO image from a disk that contains special bits
to enable booting (“El Torito” standard). Nothing special is needed when reading the
ISO from a working, bootable CD-ROM.
Please note that each BIOS manufacturer oers varying levels of support for USB boot
devices and may require conguration methods that are unique (to the manufacturer)
in order to utilize this feature. Similarly, please note that many BIOS’s provide a
simplied USB host stack and oer drivers that may not oer suitable reliability.
To create a bootable oppy, you can format the emulated oppy from the target
system, or read the data from a working boot oppy. 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 oppy) working on the Enterprise Class
KVM unit, you must adjust your BIOS settings to tell it to boot from a USB device.
Please 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 oppy image.
Network Conguration
DHCP: Automatic network conguration
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 congure
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 and
WAN ports separately. If you are using DHCP,
the values for the LAN port will be lled in
automatically and any changes made will not
aect the setup.
Domain Name Server: This section allows
you to specify DNS servers and the default
DNS domain sux in use on the network. If
