2. Introduction

The DX User IP from Minicom Advanced Systems redirects local keyboard, mouse
and video data to a remote computer. All data is transmitted via IP.

DX User IP features remote KVM access and control via a LAN or Internet
connection. DX User IP provides a non-intrusive solution for remote access and
control. Remote access and control software runs on the DX User IP embedded
processors only and not on the servers, so there is no interference with server
operation or impact on network performance.

Using one or several DX User IPs with the DX Central allows access to multiple
remote servers via single remote console. The DX User IP combines digital remote
KVM access via IP networks with a comprehensive and integrated system
management.

Figure 1 illustrates the basic configuration of the DX system with the DX User IP
and DX Users connected to peripheral devices via the DX Central.

· Place cables away from fluorescent lights, air conditioners, and machines that

are likely to generate electrical noise

· The maximum distance between each device (computer, KVM switch or second

level DX Central) and the DX Central is 100m/330ft. The maximum distance
between the DX Central and the DX User IP is also 100m/330ft.

10. Mouse synchronization limitations

The following will help ensure proper mouse synchronization between the host and
client computers.

Vendor-specific Mouse drivers

Special vendor-specific Mouse drivers disrupt the synchronization process. Ensure
these are not on the host system.

Accelerated mice

DX User IP does not work with accelerated mice. You must disable mouse
acceleration on all computers connected to the system. This is explained below for
Windows 2000 Pro, 2000 Server, XP and 2003 Server. To disable mouse
acceleration for other Operating Systems, see Appendix D on page 67.

12. Connecting the DX User IP to the Wan/LAN

The Ethernet connector on the DX User IP can be used either for a 100 Mbps
100BASE-TX connection or for a 10 Mbps 10BASE-T connection. The adapter
adjusts to the appropriate operation mode automatically.

To connect to a LAN/WAN, connect an Ethernet cable as illustrated in Figure 7. For
the Ethernet - RJ 45 connector pin-out see Appendix C.

USER GUIDE

10

10 Mbps connection

For 10BASE-T Ethernet networks, the Fast Ethernet adapter uses Category 3, 4, or 5
UTP/FTP cable. To establish a 10 Mbps connection, the cable must be connected to
a 10BASE-T hub. Ensure the cable is wired appropriately for a standard 10BASE-T
adapter. Align the RJ-45 plug with the notch on the adapter's connector and insert it
into the adapter's connector.

100 Mbps connection

For 100BASE-TX Fast Ethernet networks, the DX User IP supports Category 5 UTP
cabling. To establish a 100 Mbps connection, the cable must be connected to a
100BASE-TX hub.

1. Make sure that the cable is wired appropriately for a standard 100BASE-TX
adapter.

2. Align the RJ-45 plug with the notch on the adapter's connector and insert it into
the adapter's connector.

Note! The UTP/FTP wire pairs and configuration for 100BASE-TX cable are
identical to those for 10BASE-T cable when used with Category 5 UTP/FTP cable.

13. Local User

To use the DX User IP locally, connect a keyboard, video and mouse as illustrated
in Figure 7.

15. Order of powering on

Connect the DX User IP to the power supply using the power cord provided.

The devices and servers can be powered on at any time. Power on the DX
components in the following order:

1. The primary and secondary level DX Centrals.

2. The DX User and DX User IP units.

16. Configuring the system

The DX User IP's communication interfaces are based on TCP/IP, and it comes
configured with the values listed below.

· DHCP - disabled

· IP address - 192.168.1.22

· Net mask - 255.255.255.0

· Default Gateway - None

If the above values are unsuitable, you can change the IP configuration. This can be
done in a number of ways as set out below. We recommend configuring a fixed IP
address to the DX User IP. You can find the MAC address on the IP Extender's
underside.

Configuration via DHCP server

If you activate DHCP, DX User IP tries to contact a DHCP server on the network.
The DHCP server provides a valid IP address, gateway address and subnet mask. If
the DHCP connection fails on boot up, DX User IP boots with the last known IP
configuration.

Configuration via local console

There are 3 ways of configuring via local console:

· Serial connection

· Ethernet Crossover connection

· IP Device Setup utility

Via Serial connection

Connect the NULL modem cable to the computer and to DX User IP’s Serial 1 port.
Use any Terminal software to connect to DX User IP. The screen shots below use
Windows Hyperterminal.

USER GUIDE

12

1. Choose Start/Programs/Accessories/Communications/Hyperterminal.

2. When prompted enter a name and click OK. The Connect To box appears.
See Figure 9.

3. Fill in the connection details. Select COM 1 in the Connect using box and
click OK. The COM 1 properties box appears. See Figure 10.

Figure 9 Connect To box

Figure 10 COM 1 Properties box

DX USER IP

4. Set the port settings to the following values:

· Bits/second - 115200

· Data bits - 8

· Parity - None

· Stop bits - 1

· Flow Control - None

5. Click OK. The Hyperterminal appears. See Figure 11.

Figure 11 The Hyperterminal

6. Press Enter. Some device information and a prompt appear.

7. Type config and press Enter. Configuration questions appear. DHCP must be
disabled. You can change the IP address, net mask and default gateway. Pressing
Enter without entering values keeps the default values. To contact DX User IP
from outside the LAN, configure a gateway. To remove an already configured
gateway, type 0.0.0.0.

The last question – enable IP access control – concerns switching IP packet

filtering on or off. This can re-enable access to DX User IP after an incorrect IP
access configuration has been activated. Page 44 has more information on IP
access control.

8. Confirm the settings. DX User IP resets the configuration.

USER GUIDE

14

Via Ethernet Crossover connection

Connect an Ethernet Crossover cable to the DX User IP and to the computer back­to-back, the DX User IP is configured to 192.168.1.22, configure your computer to
use a static IP in that range. For example 192.168.1.10. Open your browser and type

192.168.1.22. Configure the device via the WEB interface.

Via the IP Device Setup utility

The IP Device Setup utility is located on the supplied CD under Customer
Support/Utilities. Click the IP Device Setup Figure 12 appears.

Figure 12 IP Device Setup utility

The utility locates DX User IP devices on the network and configures them to use a
static IP / DHCP / or Bootp configuration. You can also configure a new password
for the IP device. All other configurations must be done via the Serial / Web
interface methods.

17. The DX User IP system interface

Operate the DX User IP system through one of the following interfaces:

1. HTTP/HTTPS - Any standard Web browser. Depending on the Web browser, you

can access the DX User IP card using the unsecured HTTP protocol or, in case the
browser supports it, the encrypted HTTPS protocol. We recommend using HTTPS
when possible.

3. Telnet - Use a standard Telnet client to access an arbitrary device connected to

one of the DX User IP's serial ports via a terminal mode.

2. SNMP (Simple Network Management Protocol) - Any standard SNMP client can

use this protocol.

All the above interfaces are accessed using the TCP/IP protocol. They can thus be
used via the built-in Ethernet adapter or modem.

DX USER IP

15

This section deals with the HTTP interface. The other two interfaces are explained
on pages 19 and 45.

The Web browser must come with a Java Runtime Environment version 1.1 or
higher. Without Java support, you can still maintain the remote host system using
the administration forms displayed by the browser.

We recommend the following browsers for an unsecured connection:

· For Windows 98, ME, 2000 and XP, Microsoft Internet Explorer 5.0 or

higher

· For Windows 98, ME, 2000, and XP, Linux and other UNIX like operating

systems Netscape Navigator 7.0 or Mozilla 1.0

To access the remote host system using a securely encrypted connection you need a
browser that supports the HTTPS protocol. Strong security is only assured by using
key length of 128 Bit. We recommend the following browsers.

· Microsoft Internet Explorer version 5.5 or higher with Windows 98, ME,

2000 and XP

· Netscape Navigator 7.0 or Mozilla 1.0 with Windows 98, ME, 2000, and

XP, Linux and other UNIX like operating systems

18. Logging in

Type the IP address into the Web browser. Either http://192.168.1.22 for an
unsecured connection. Or https://192.168.1.22 for a secured connection. The Login
screen appears. See Figure 13

Figure 13 The Login screen

Initially there is only one user who has unrestricted access to all DX User IP
features. Type the default Login name ‘super’ and Password ‘smart’ and click
Login. The DX User IP Home page appears. See Figure 14.

USER GUIDE

16

Figure 14 The DX User IP Home page

19. Timeout

After half an hour of non-activity the system automatically logs out. Clicking
anywhere on the screen will lead back to the Login screen.

20. The Work area

The Work area has a short summary about your DX User IP.

· Server Power Status - On or Off

· Firmware Version - installed on your DX User IP

· Device management – self managed or connected to a management device

· Users - all currently logged in users and IP addresses. (Note: when

connected through a proxy server the IP address will be that of the proxy
server).

RC – Remote Control open. Exclusive – Exclusive mode. Idle – time since
last activity.

21. Remote Console Settings

Before connecting to the remote console you must configure all required settings. To
do so, from the DX User IP Menu click Remote Console Settings. The Remote
Console Settings window appears. See Figure 15.

DX USER IP

17

Figure 15 The Remote Console Settings

All settings are user specific. Choose a user from the Drop-down menu.

Transmission Encoding

Transmission Encoding optimizes the speed of the remote screen depending on the
number of parallel users and the bandwidth of the connection line.

Automatic Detection - The encoding and the compression level is determined
automatically from the available bandwidth and the current content of the video
image.

Pre-configured – Choose the connection method.

Manually: Compression - For low bandwidth connections. 1 is the lowest and 9 the

highest compression rate. The DX User IP takes time to compress the data. This
option shouldn't be used when many users want access simultaneously.

Color Depth – The lower the depth the faster the speed.

USER GUIDE

18

Various Remote Console Options

Start in Monitor Mode - Check this option to open the Remote Console window in
read only mode. (No keyboard or mouse transferred to Host computer).

Exclusive Access- Enables the Exclusive Access mode at Remote Console startup.
This forces the Remote Consoles of all other users to close. No one can open the
Remote Console until this user disables the Exclusive Access or logs off.

Remote Console Type

Default Java VM – Uses your Browser’s default Java Virtual Machine. This may
be the Microsoft JVM for Internet Explorer or Sun JRE if it is configured this way.
Use of the Sun JRE may also be forced (see below).

Sun Microsystems Java Browser Plugin - Uses Sun Microsystems Java Browser
Plugin - Sets the administration system’s Web browser to use the JRE (Java
Runtime Environment) of Sun Microsystems. JRE is used to run the code for the
Remote Console window, which is actually a Java Applet. If the Java plug-in is not
installed on your system, it will be downloaded and installed automatically. The
download is about 15 Mbytes. JRE provides a stable and identical Java Runtime
Environment across different platforms. The Remote Console software is optimized
for this JRE version and offers wider range of functionality when run in SUN's JRE.

Tip! The software is on the supplied CD. So, if you have a slow Internet connection,
pre-install the JRE on your administration machine.

ActiveX control - Use an ActiveX control instead of a Java applet - This is the
ActiveX-Control of the KVM Vision Viewer - an application available separately.
You must install the viewer on your local system. See the Viewer Guide for further
information. This option only works with Microsoft Internet Explorer on Win32
Systems. KVM Vision Viewer is on the supplied CD.

Mouse hotkey - Used for fast mouse synchronization in Double Mouse mode and to
free the grabbed mouse when in single mouse mode.

Remote Console Button Keys - Button Keys simulate keystrokes on the remote
system that cannot be generated locally. For example `Control + Alt + Delete' on
Windows and DOS or `Control + Backspace' on Linux.

Define a new Button Key as follows:

Type the required keys e.g. Ctrl+Alt+Delete. The + sign means that the keys are
pressed together. The – sign means the keys are pressed sequentially.

The * sign inserts a pause with a definable duration. See page 25.

DX USER IP

19

To require a confirmation request before keystrokes are sent, write confirm at the
start. E.g. confirm Ctrl+Alt+Delete.

For a list of key codes and aliases DX User IP recognizes, refer to Appendix B on
page 63.

Press Apply for the changes to take effect.

Home Page Refresh – Refreshes the DX User IP Home page, so that direct Smart
IP Links updates their status.

22. Telnet Console

The Telnet Console offers a Java applet for the Telnet protocol to open a connection
to DX User IP. Its main use is the pass through option for the Serial port 1 explained
on page 38. The Telnet access has to be enabled in the security settings as well, see
page 44. It is also possible to connect with a standard Telnet client.

Access via Telnet

Connect via a standard Telnet client using DX User IP’s Telnet server. Use it for
passthrough access to a device connected to Serial port 1. Connect any serial device,
which offers terminal access via its Serial port and access it using the Telnet
interface. Set the Serial port settings according to the requirements of the device –
explained on page 39.

Connect to DX User IP in the usual way required by the Telnet client, e.g. in a
UNIX shell: telnet 192.168.1.22 – (The IP address has been replaced by the one
that is actually assigned to DX User IP).

Type a username and password when prompted. These are identical to those of the
Web interface. The user management of the Telnet interface is controlled just like
the Web interface.

Once logged in, the command line appears to type management commands.

The interface supports both the command line and terminal modes. The command
line mode is used to control or display some parameters. In terminal mode the
passthrough access to serial port 1 is activated (if the serial settings were made
accordingly). All inputs are redirected to the device on serial port 1 and the answers
appear on the Telnet interface.

Telnet server commands

Click help to list the following commands:

cls - Clears screen

USER GUIDE

20

quit - Logs out current user and disconnects from the client.

version - Shows all available version numbers

terminal - Starts the terminal passthrough mode for serial port 1. The key sequence

`<esc> exit' switches back to command modus.

23. Status via IPMI

The Status via IPMI function shows the current values and the min/max-thresholds
of all fans, temperatures and voltages existing in the host system. Change the
thresholds by editing the values and pressing Apply.

The first time you call this page, it can take up to two minutes until the sensor data
appears.

Note: If IPMI is disabled, Status via IPMI and System Log via IPMI are not
available (the menu options are not visible).

24. Event Log via IPMI

The Event Log via IPMI accesses the SEL (System Event Log) repository and reads
every entry sequentially. The first time you use this function after starting DX User
IP the complete repository has to be read, what may take 1 or 2 minutes.

After reading all entries, DX User IP displays them with their time, sensor and
description in accordance with the filter settings. You have the choice between
several pre-settings (i.e. last day, last week) or an exact declaration of the start and
the end date.

Once you change the filter settings, click `Update' to update the shown entries. If the
Get sensor names box is checked, all sensor IDs are shown with their respective
names.

The time shown in the log entries is the SEL time, meaning it is independent of the
system time. The SEL time is shown at the top of the log table. Click Clear Event
Log to delete all entries in the SEL repository.

25. File transfer – Virtual Floppy

This feature does not currently work.

26. Power Control

The appearance of the power control window depends on the power control option
connected to DX User IP and on the currently activated setting (discussed on page

40). There are 4 options available: Power control disabled. Internal power. External

power. Power control via IPMI.

DX USER IP

21

Internal power

Once connected, enable the internal power option using the Serial Port settings on
page 40.

The Power Control panel enables access to the most important external buttons of
your host system. These buttons are the reset and the ATX power button.

The power button represents the ATX power button on your host system. It is used
to switch the power supply on and off. The ATX power button has 2 operation
modes: a short press, and a press of about 4 seconds. As shown in Figure 16 these
two modes are supported separately. The 2 operation modes are explained in the
next section.

Figure 16 Internal Power Control

Note: The prerequisite for the remote power/reset button to work is a correct
installation of DX User IP.

The Remote reset and power button effects are as follows:

Reset - This is similar to pressing the reset button directly on the remote system.
Pressing the reset button will result in a cold start of the system. This might damage
open files and the file system itself.

Power (short press) - A short press on the ATX button is normally caught by the
running operating system that tries to initiate a controlled shut down. Do this to
switch off the system. If this does not work try the long press button.

After pressing, the power state displayed in the administration panel won't
immediately reflect the requested change. A controlled shut down of the system may
take some minutes. Observe the action caused by your button press using the
Remote Console window or by reloading the Server Power Control panel.

Power (long press) - This will unconditionally power off the system. Even if you
have submitted a short press before, this will shut down the power supply of the host
system. The effect of the long button press can be immediately observed on the
panel that is loaded into the browser because of the button press. The power state
will be off.

USER GUIDE

22

External power

If the external power option is enabled it will look like Figure 17.

Figure 17 External power control

The upper half is used to switch the power for the KVM port currently active. Use
the KVM settings – see page 24 - to assign a port of the external power control to a
KVM port. If no assignment exists, the option is disabled.

The lower half offers controls for switching each port of the external power control
directly. Select the appropriate port and decide whether to power it off or on.

If IPMI is enabled, the power control functions are performed over IPMI requests.
This may take a few seconds.

If IPMI is disabled, the power control functions are performed through the internal
or external power control options.

27. Keyboard & Mouse Settings

Click Keyboard & Mouse Settings. Figure 18 appears.

To make the remote keyboard and mouse work properly the DX User IP settings for
the host's mouse and keyboard types must be correct.

DX User IP supports different keyboard and mouse types.

G&D Equalizer – This supports the mouse synchronization for Guntermann &
Drunck KVM switches. These switches perform an internal rescaling of the mouse
movements, which cause the existing algorithm to break if DX User IP is connected
behind such a switch. This option detects the rescaling and compensates for it, so
that the mouse synchronization works. Do not select this option for the DX User IP­it may disrupt the normal mouse synchronization.

1. Assign names for each port.

2. Define hotkeys to switch to each port.

Choose either Minicom default hotkeys by selecting Minicom KVM-Switch in the
Default configuration box, and then click the Set Defaults button.

Or choose your own hotkeys. The syntax to define a new hotkey is as follows:
<keycode> [ + | - | * ] <keycode>.

For example LShift-LShift-*1-Enter. A + sign means that the keys are pressed
together. The – sign means the keys are pressed sequentially. Lshift means the left
Shift key.

The * sign inserts a pause with a definable duration. Add more than one pause if
necessary. See Appendix B on page 63 for a list of key codes.

3. Press Apply at the bottom of the page. The settings are saved.

DX User IP uses separate mouse synchronization settings - see page 58 - and video­settings - see page 57 - for each port.

Note:

It is still possible to apply OSD key combinations through the Remote Console for
switching the KVM port. However, video and mouse synchronization settings will
be shared among the ports and may be unintentionally changed for one of those
ports.

Enable local video port

This option decides if the video output on the local monitor connected to DX User
IP is active and passing through the incoming signal from the host system.

Use this option to switch off the local monitor connected to DX User IP when
accessing sensitive information on the Host computer.

Noise filter

Define how DX User IP reacts to small changes in the video input signal. A large
tolerance needs less network traffic and leads to a faster video display, but small
changes in some display regions may not be recognized immediately. A small
tolerance displays all changes instantly but may lead to a constant amount of
network traffic even if display content is not really changing (depending on the
quality of the video input signal). The default setting should be suitable for most
situations.

DX USER IP

29

Custom Video Modes

DX User IP recognizes a limited number of common video modes. When running
X-Window on the host system, don't use any custom modelines with special video
modes. If you do, DX User IP may not be able to detect these. Use any standard
VESA video mode. Refer to Appendix A on page 62 for a list of all known modes.
If your video mode differs from the standard VESA video mode, you can add up to
4 Custom Video Modes.

Add video modes to DX User IP, which are not recognized using the factory
settings, when for example using special modelines in an X-Window configuration
on the host or with uncommon hosts or operating systems.

Click Add Custom Video Modes. The Custom Video Modes window appears see
Figure 24.

Note! This option may affect the correct video transmission and is for advanced
users only.

32. User/Group Permissions

From the DX User IP Menu choose User/Group Permissions. The User/Group
Permissions settings appear. See Figure 26.

Figure 26 User/Group Permissions

Each user or group has a set of access rights to the DX User IP functions. The user
super always has unalterable full access rights. A newly created user has the access
rights of all groups he belongs to.

You can change the access rights in the User/Group Permissions panel. The panel
shows the changes to the access rights inherited by the user's ancestors only. This
means an empty user permission list has exactly the same access rights as the groups
he belongs to.

When one user creates a new user, he can alter his access rights. A user can change
another user or group's access rights if he stands higher in hierarchy. The 'super' user
stands at the top of the hierarchy, and can change everybody's access rights.

A user can never give more access rights than he himself has but he can always
reduce the access rights.

USER GUIDE

34

To change access rights:

1. From the Drop down list select a user/group. The selection list shows only users

and groups, which you have the right to change.

2. Click the Update button. The access rights of the user appear. The meaning of the

Permissions is as follows:

Viewing a field. allow view means you can view it. deny access means you cannot
view it.

Changing a field setting. Allow change means you can change it. (This doesn’t give
an automatic right to view the value, the allow view value must also be set). Deny
change means you cannot change it.

Using a function. allow access means you can use it. deny access means you cannot
use it.

3. Select the desired permission and click Apply.

33. Network Settings

From the DX User IP Menu choose Network Settings. The Network Settings appear.
See Figure 27.

Figure 27 The Network Settings

can also connect to the DX User IP using its pre-configured IP settings.

DX USER IP

35

Warning! Changing the network settings of DX User IP may result in losing the
connection. If you remotely change the settings ensure that all values will give you
access to the DX User IP.

IP auto configuration

Choose between the 3 options.

None – no IP auto configuration. In this case type a static IP address in the
appropriate settings below.

DHCP - When selected, DX User IP will contact a DHCP (Dynamic Host
Configuration Protocol) server in the local sub-net to obtain a valid IP address,
gateway address and net mask. Before you connect DX User IP to your local sub­net, complete the corresponding configuration of your DHCP server.

BOOTP - When selected, DX User IP will contact a BOOTP (Bootstrap Protocol)
server in the local sub-net to obtain a valid IP address, gateway address and net
mask.

IP address

Static IP address in the usual dot notation.

Subnet mask

The net mask of the local network.

Gateway IP address

In case the DX User IP should be accessible from networks other than the local one,
this IP address must be set to the local network router's IP address.

Primary DNS Server IP address

IP address of the primary Domain Name Server. This may be left empty, however
DX User IP won't be able to perform name resolution.

Secondary DNS Server IP address

This address will be used in case the Primary DNS Server can't be contacted.

Primary Time Server

IP address of the primary NTP (Network Time Protocol) compliant timeserver. DX
User IP will synchronize its own absolute time with the timeserver's one. This is
important for writing log entries and for the Dynamic DNS Service.

USER GUIDE

36

Secondary Time Server

This address will be used in case the Primary Time Server can't be contacted.

Remote Console & HTTPS port

Port number at which DX User IP's Remote Console server and HTTPS server are
listening. If empty the default value is used.

HTTP port

Port number at which DX User IP's HTTP server is listening. If empty the default
value is used.

Telnet port

Port number at which DX User IP's Telnet server is listening. If empty the default
value is used.

Bandwidth limitation

Figure 28 Dynamic DNS scenario

DX USER IP

37

DX User IP is reachable via the IP address of the DSL router, which is dynamically
assigned by the provider. Since the administrator doesn't know the IP address
assigned by the provider, DX User IP connects to a special dynamic DNS server in
regular intervals and registers its IP address there. The administrator can contact this
server as well and pick up the same IP address belonging to his card.

The administrator has to register a DX User IP that is supposed to take part in the
service with the Dynamic DNS Server. He will get an approved nickname and
password in return to the registration process. This account information is needed in
order to determine the IP address of the registered DX User IP.

To enable the Dynamic DNS:

1. Ensure the DX User IP LAN interface is properly configured.

2. From the DX User IP menu choose Network Settings / Dynamic DNS. The

Dynamic DNS Settings appear. See Figure 29.

Figure 29 Dynamic DNS Settings

3. Check the Enable Dynamic DNS box.

4. Change the settings as desired.

Hostname - The Hostname registered during manual registration with the Dynamic
DNS Server. Spaces are not allowed in the Hostname.

Username/Password – Fill in the Username and Password.

Check time - DX User IP card registers itself in the Dynamic DNS server at this

time.

USER GUIDE

38

Check interval - Interval for reporting again to the Dynamic DNS server by DX
User IP.

DX User IP has its own independent real time clock. Ensure the time setting is
correct by configuring a timeserver see page 35.

DX User IP registers itself to the Dynamic DNS server slightly different from the
time configured. To reduce load peaks on the server we add a random time (0-10
min) to the absolute time value.

35. Serial Port Settings

From the DX User IP Menu choose Serial Port Settings. The Serial Port Settings
appear. See Figure 30.

Figure 30 Serial Port Settings

In the DX User IP Serial Settings specify the devices connected to the two Serial
ports.

Serial Port 1

The port options are listed below

Configuration login –If this option is checked you can only use the port for the
initial configuration and no other function.

Modem - DX User IP has the option of remote access using a telephone line.
Connect the modem to Serial 1 port. Using a telephone line means building up a
dedicated point-to-point connection from your console computer to the DX User IP.

DX USER IP

39

The DX User IP acts as an Internet Service Provider (ISP) to which you can dial in.
The connection is established using the Point-to-Point Protocol (PPP).

Before connecting to DX User IP, configure your console computer accordingly. For
instance on Windows based operating systems you can configure a dial-up network
connection, which defaults to the right settings like PPP.

Serial line speed - Most modems today will support the default value of 115200
bps. For older modems lower the speed.

Modem Init String - Initialization string. The default value works with all modern
standard modems connected to a telephone line. For special modems or if connected
to a local telephone switch that requires a special dial sequence to connect to the
public telephone network, change this setting by giving a new string. See the
modem's manual about the AT command syntax.

Modem Server IP address – This address is used only when connecting to DX
User IP via a modem. When you dial into the DX User IP the client computer will
receive a Modem Client IP address from the DX User IP. Open the Web browser
and type Modem server IP address to login to the DX User IP.

The Client IP (see paragraph below) must be in the same class C subnet as the server
IP. This subnet should not conflict with the Ethernet subnet on the client side and
with the Ethernet subnet on DX User IP Network side.

Modem Client IP address - This address is assigned to your console computer
during the PPP handshake. Since it is a point-to-point IP connection virtually every
IP address is possible but ensure, it is not interfering with the IP settings of DX User
IP and your console computer. The default value will work in most cases.

IPMI over Serial - Check to use this Serial port for IPMI 1.5 over serial. See page
47 for more information.

Passthrough access to serial port via Telnet - Connect an arbitrary device to the
serial port and access it (assuming it provides terminal support) via telnet. Select the
appropriate options for the Serial port and use the Telnet Console (see page 19) or a
standard telnet client to connect to DX User IP.

External Power Option – When the External Power Option is the Sentry Power
Tower or Baytec RPC series connected to Serial port 1, configure it by clicking
change external power switch option. The External Power Option for Serial port 1
window appears.

Fill in the Username and password as defined by the Sentry Power Tower.

Force HTTPS - Access the Web front-end only using an HTTPS connection. DX
User IP won't listen on the HTTP port for incoming connections.

KVM encryption - Controls the encrypting of the RFB protocol, used by the
Remote Console to transmit the screen data to the administrator machine and
keyboard and mouse data back to the host.

Off - No encryption used.

Try - Tries to make an encrypted connection. If unsuccessful, an unencrypted

connection is used.

Force - Makes an encrypted connection.

SSL Certificate Management

DX User IP uses the SSL (Secure Socket Layer) protocol for any encrypted network
traffic between itself and a connected client. When connecting, DX User IP reveals
its identity to a client using a cryptographic certificate. This is the same for all DX
User IPs and won't match the network configurations applied to the card by its user.
The certificate's underlying secret key is also used for securing the SSL handshake.
Hence, this is a security risk (but better than no encryption at all).

You can generate and install a new certificate unique to a particular card. DX User
IP can generate a new cryptographic key and the associated Certificate Signing
Request that needs to be certified by a certification authority (CA). A CA verifies
you are who you claim to be and signs and issues a SSL certificate to you.

DX USER IP

43

To create and install a DX User IP SSL certificate:

1. From the Security Settings page choose Create your own SSL certificate. The

window appears as in Figure 35.

Figure 35 CSR

2. Fill in the fields:

Common name - Network name of DX User IP once installed in the user's network.
It is identical to the name that is used to access the card with a Web browser. In case
the name given here and the actual network name differ, the browser will pop up a
security warning when the card is accessed over HTTPS.

Organizational unit - Specifies which department within an organization DX User
IP belongs.

Organization/Locality/City/State/Province - Organization to which DX User IP
belongs + location.

Country - Use the 2 letter ISO code, e.g. DE for Germany.

BMC address - Hexadecimal Baseboard Management Controller address. Needed
for all types of communication to the IPMI-interface. Usually you can find this
address in the BIOS of the host system. The default and common value is 20.

IPMI over Serial - If your host system supports IPMI V1.5 and has an Intel EMP
(Emergency Management Port, usually COM2) connector, you can connect IPMI
through serial port 1 on DX User IP. Please note:

· Set the EMP port to Always enable and switch off the Restricted Mode.

· The BMC should accept a null username and a non-null password account

as login.

· Passwords are 4 -16 characters long.

· Use a null modem cable for connection

IPMI over LAN - You can connect the IPMI over a LAN connection. You need a
host system with IPMI V1.5 and a network adapter with a sideband connection to
the BMC (mostly on board). In the IPMI Settings, enter the IP-address of this host
system and the correct password for the LAN connection.

You can also access other IPMI systems when you enter their IP address.

Click the link to access the DX User IP data file. The file contains support
information, which will help us to troubleshoot your problem.

Include/modify custom HTML code

You can modify the HTML code of the Home page to include customized graphics
and text. You can’t save graphics on the DX User IP therefore the graphics should
be accessible on the Network. Define Primary and secondary DNS in the Network
settings if needed.

The system is now fully configured, you can now access the remote console.

USER GUIDE

54

41. Accessing the remote console

From the menu click Show Remote Console. The DX Login screen appears inside
the remote console. See Figure 44.

Figure 44 The DX Login screen inside the remote console

Go to the DX Operating Guide

Type the default username ‘admin’ and password ‘admin’.

To configure/manage the devices connected to the DX system see the DX Operating
Guide.

You can work on the remote console with the keyboard and mouse. The delay with
keyboard and mouse reactions - if any - depends on the line connection bandwidth.

42. Keyboard layout

Your host keyboard changes its layout to match the remote host system. So for
example if the host system uses a US English keyboard layout, special keys on a
German keyboard won't work but will function as US English keys.

To solve this problem, adjust the remote system keyboard to the same mapping as
your host one. Alternatively, use the Soft-Keyboard that is part of the Remote
Console applet.

DX USER IP

55

The Remote Console window is a Java Applet that tries to establish its own TCP
connection to DX User IP. The protocol that is run over this connection is not HTTP
or HTTPS but a protocol called RFB (Remote Frame Buffer Protocol). Currently
RFB tries to establish a connection to port number 443. Your local network
environment must allow this connection to be made, i.e. your firewall and, in case
you have a private internal network, your NAT (Network Address Translation)
settings must be configured accordingly.

In case DX User IP is connected to your local network environment and your
connection to the Internet is available using a proxy server only without NAT being
configured, the Remote Console is very unlikely to be able to establish the according
connection. This is because today's Web proxies are not capable of relaying the RFB
protocol. In case of problems, please consult your network administrator in order to
provide an appropriate network environment.

The Remote Console window shows the remote screen at its optimal size. However,
you can always resize the Remote Console window in your host window system.

Hint: The Remote Console window on your local window system is just one
window among others. To make the keyboard and mouse work, your Remote
Console window must have the local input focus.

43. The Control buttons /toolbar icons

The control buttons/toolbar icons have the following functions:

- Sends the `Control Alt Delete' key combination to the remote

system.

Auto adjust - Adjusts the screen to the best visual quality

Sync mouse - Synchronizes the host and remote mice. Necessary when
using accelerated mouse settings on the host system. There is generally no need to
change mouse settings on the host.

- Discussed on page 59.

Click the Options button to get the following options:

Monitor Only - When turned on, the Remote Console does not accept keyboard /

mouse input. The top right hand icon appears like this .

USER GUIDE

56

Exclusive access - If a user has the appropriate permission, he can force the Remote
Consoles of all other users to close. No one can open the Remote Console until this
user disables the Exclusive access or logs off.

Readability Filter - Turn the filter on in scaling mode to preserve most of the
screen details. Only available with a Java Virtual Machine version number of 1.3 or
higher.

Scaling - Scale down the Remote Console. Not all display details will be preserved.

Mouse handling - The submenu for mouse handling offers two options for

synchronizing the host and the client mouse pointer - explained on page 58. The
option for 'Fast Sync' shows the hotkey if you defined one using the Remote
Console Settings.

Local cursor - Choose a cursor shape for the host mouse. The number of available
shapes depends on the Java Virtual Machine, only version 1.2 or higher offers the
full list.

Chat Window - Opens the Chat window

Video Settings – To adjust the video settings.

Refresh video - Refreshes the video

Soft Keyboard - Opens the soft-keyboard menu:

· Click Show. The soft-keyboard appears.

· Click Layout. Choose layout

· Click Mapping. Choose the desired language and country

Local Keyboard - Used to change the language mapping of your browser machine
running the Remote Console Applet. Normally the Applet determines the correct
value automatically. However, depending on your particular JVM and your browser
machine settings this is not always possible. A typical example is a German
localized system that uses a US-English keyboard mapping. In this case you have to
change the Local Keyboard setting manually to the right language.

KVM keys – Each key represents a port. See page 26 to define hotkeys to switch to
each port. The keys also appear in the toolbar.

Hotkeys - Button Keys simulate keystrokes on the remote system that cannot be
generated locally. To define hotkeys see page 18.

Encoding – Choose the desired options from the Compression and Color Depth
drop down menus.

DX USER IP

57

Information bar - Shows the console and connection state and remote screen size.
The value in round brackets describes the connection to the remote system: Norm
stands for a standard connection without encryption; SSL stands for a secured
connection. Double click the bar to see a history of all the status information.

44. The Chat window

Use the Chat window to chat with others logged into the system. Figure 45
illustrates the Chat window.

Type here

Figure 45 Chat window

All messages are broadcast to ALL connected users. There is no option to direct a
message to a particular user only. There is no message history, so messages can only
be received after opening the Remote Console. Type your message and press Enter.
To end the Chat, close the Chat window.

45. The Video settings

From the Options menu choose Video Settings. The Video Settings box appears. See
Figure 46.

Figure 46 The Video settings

USER GUIDE

58

The parameters have the following functions:

Brightness - Brightness control.

Contrast Red/Green/Blue- RGB contrast control.

Clock - Sets the horizontal frequency for a video line, this depends on the video

mode. Different video cards may require different values. The default settings and
auto adjustment procedure should be adequate for all common configurations. If not
change this setting together with the sampling phase.

Phase - Sets the phase for video sampling.

Horizontal Offset - Moves the picture in a horizontal direction.

Vertical Offset - Moves the picture in a vertical direction.

Brightness and contrast affect all modes and KVM ports globally; the other settings
are changed specifically for each mode on each KVM port.

- Resets mode to factory defaults.

- Resets all modes to factory defaults.

- Saves changes.

- Undoes changes that have not yet been saved.

46. Video Settings access

In the User/Group Permissions section on page 33, it explained how to set access
levels for all parameters including Video Settings access. A Remote Console user
can always change Brightness, Contrast and picture positions, whatever his Video
Settings access rights. A user who has permission to change the Video Settings can
also change the Clock and Phase parameters and use the reset buttons.

Hint. Always press the Auto Adjust video button before operating the
computer. The screen should be inside the borders of Remote Control window. If the
video doesn’t synchronize properly or there is a lot of incoming traffic, reset all
modes and synchronize video again to improve video transfer.

47. Mouse synchronization

There are two ways to synchronize the host and remote mice:

Fast Sync - Choose Options / Mouse Handling / Fast Sync. This corrects a
temporary, but fixed skew.

DX USER IP

59

Intelligent Sync - If fast sync doesn't work or the mouse settings have been changed
on the host system use the Intelligent Sync option.

To do so:

1. Ensure the picture is correctly adjusted, Click Auto Adjust or manually correct

the picture using the Video Settings.

2. Choose Options / Mouse Handling / Intelligent Sync.

Pressing the button leads to a fast sync, except when the video mode
recently changed.

Note! For the intelligent sync to work, the picture MUST be correctly adjusted. Use
the auto adjustment function or the manual correction in the Video Settings panel to
adjust the picture. The video must also be of sufficiently good quality.

Single mouse mode

The information above applies to the Double Mouse Mode, where remote and host
mouse pointers are visible and need to be synchronized. There is also the Single
Mouse mode. In this mode only the client mouse pointer is visible.

Single Mouse mode needs a Sun Java Virtual Machine 1.3 or later.

Select the mode in the Remote console – see Figure 44.

From the Options menu choose Mouse Handling/Mouse Mode/ Single Mouse Mode.

Or press from the Control Buttons toolbar. The client mouse pointer can be
controlled directly.

To leave this mode, you must define a mouse hotkey in the Remote Console Settings
Panel – see page 18. Press this key to free the captured host mouse pointer.

Frequently Asked Questions

Q 1: The client mouse doesn't work or is not synchronized.

A: Ensure the DX User IP mouse settings match the mouse model. Also see page 58

Q 2: Bad video quality or grainy picture

A: Use the brightness and contrast settings - see page 57. Use the auto adjustment
feature to correct a flickering video.

Q 3: Login fails.

A: Was the correct user and password given? On delivery, the user "super" has the
password "smart". Configure your browser to accept cookies.

Q 4: I use the Mozilla Browser 0.9.x., Netscape 6.x and https (secure http). When I
try to open the Remote Console applet loading fails with Bad Magic Number
Exception.

A: This is a bug in some older versions of Mozilla. Don't use https, or upgrade your
Browser.

Q 5: The Remote Console window can't connect to DX User IP.

A: Maybe a firewall prevents access to the Remote Console. Ensure the TCP port
numbers 443 or 80 are open for incoming TCP connections.

Q 6: Cannot connect to DX User IP.

A: Check if the network connection is working (ping the IP address of DX User IP).
If not, check network hardware. Is DX User IP powered on? Check if the IP address
of DX User IP and all other IP related settings are correct. Also verify that all the IP
infrastructure of your LAN, like routers are correctly configured. Without a ping
functioning, DX User IP can't work.

Q 7: Special key combinations, e.g. ALT+F2, ALT+F3 are intercepted by the
console system and not transmitted to the host.

A: Define a so-called 'Button Key'. This can be done in the Remote Console
settings.

Q 8: In the browser the DX User IP pages are inconsistent or chaotic.

A: Ensure your browser cache settings are feasible, and are not set to something like
"never check for newer pages". Otherwise DX User IP pages may be loaded from
your browser cache and not from the card.

Q 9: Windows XP doesn't awake from standby mode

A: This is possibly a Windows XP problem. Try not to move the mouse while XP
goes into standby mode.
