Chapter 1: Introduction
Product Overview
The ARMC/3P is a manufacturer-independent remote administration system. The ARMC/3P works as an integrated solution on your server system. Based on an embedded operating system, the ARMC/3P provides both exceptional stability and permanent availability independent of the present state of the server’s operating system. As a system administrator, you have entire control and location-independent remote access to react upon both critical incidents and cases of necessary maintenance.

Product Features
The ARMC/3P defines a new class of remote access devices. It combines digital remote access via IP networks with comprehensive and integrated system management. The ARMC/3P offers convenient, remote KVM access and control via LAN or Internet. It captures, digitizes, and compresses video and transmits it with keyboard and mouse signals to and from a remote computer. Remote access and control software runs on its embedded processors only, but not on mission critical servers, so there is no interference with server operation or impact on network performance.
Furthermore, the ARMC/3P offers additional remote power management with the help of
optional available devices. Features of the ARMC/3P are:
- KVM (keyboard, video, mouse) access over IP or telephone line
- No impact on server or network performance
- Automatically senses video resolution for best possible screen capture
- High-performance mouse tracking and synchronization
- Port to connect a user console for direct analogous access to KVM device
- Local mouse suppression (only when using SUN’s Java Virtual Machine)
- Remote Power Management
- Remote Virtual Media

When the Server is up and running
The ARMC/3P gives you full control over the remote server. The Management Console allows you to access the remote server’s graphics, keyboard and mouse and to send special commands to the server. You can also perform periodic maintenance of the server. Using the Console Redirection Service you can do the following:
• Reboot the system (a graceful shutdown)
• Watch the boot process
• Boot the system from a separate partition or from Virtual Media
to load the diagnostic environment or install operating systems
• Run special diagnostic programs

When the Server is dead
Obviously, fixing hardware defects is not possible using a remote management device. Nevertheless, the ARMC/3P gives the administrator valuable information about the type of a hardware failure. Serious hardware failures can be categorized into five different categories with different chances to happen 1:
Table 1 Hardware Failures
Category Probability

Connecting with Front Panel Connector
There are motherboards which do not have separated pins for power on/off and reset. Both the reset and the power buttons are placed on the system’s front panel and connected to the motherboard via a common front panel connector. To allow the connection of the ARMC/3P’s remote reset and power on/off signals to those motherboards a special front panel adapter has to be placed between the front panel connector on the motherboard and the cable connector to the front panel. Please ask your local service center for assistance.
Connecting Power Supply
The ARMC/3P offers the possibility to be powered internally by the host system using the ATX Power Adaptor cable or powered externally using the external Power adaptor. (see Package Contents).
Connecting Power using ATX Power Cable Adaptor
If the host system provides an ATX 20 or ATX 24 (EPS) connection from the power supply to the motherboard, this cable can be extended with the delivered ATX Power Cable Adaptor. In that case the ARMC/3P is powered internally using the 5V Standby Power of the host power supply. There is no other external power supply necessary.
For connecting the ATX Power Cable Adaptor obey the following steps while referring to Figure 7.
1. Power off the host and disconnect it from the power line.
2. Find the ATX cable connecting the host system power supply and the motherboard and remove the cable.
3. Exchange the disconnected cable with the delivered 20-pole ATX Power Cable Adaptor or the 24-pole ATX Power Cable Adaptor (EPS) cable. Then, connect the male connector of the enclosed ATX Power Cable Adaptor to the power supply of the host system and connect the female connector of the enclosed ATX Power Cable Adaptor to the power connector of the motherboard.
4. Connect the ATX Power Cable Adaptor male connector on the ARMC/3P with the 5 pin female connector of the ATX Power Cable Adaptor. Refer to Figure 16 ARMC/3P Host Power pins
5. Check the cabling, finally.

Initial Configuration via DHCP Server
By default, the ARMC/3P will try to contact a DHCP server in the subnet to which it is physically connected. If a DHCP server is found, it may provide a valid IP address, gateway address and net mask. Before you connect the device to your local subnet, be sure to complete the corresponding configuration of your DHCP server. It is recommended to configure a fixed IP assignment to the MAC address of the ARMC/3P. You can find the MAC address on the outside of the shipping box and on the bottom side of the ARMC/3P. If this initial configuration does not meet your local requirements, use the psetup tool to adjust the values to your needs. The psetup tool can be found on your ARMC/3P CD. You can follow the procedure described below.
Initial Configuration via Serial Console
To configure the ARMC/3P via serial interface both a serial port replicator cable and a null modem cable are required. Using a serial terminal, the ARMC/3P has a serial line interface (rear bracket). This connector is compliant with the RS 232 serial line standard. To establish a serial connection use a standard NULL-Modem cable. The serial line has to be configured with the parameters given in Table 5. When configuring with a serial terminal, reset the ARMC/3P and immediately press the ESC key. You will see some device information, and a “=>” prompt. Enter config, press Enter and wait for a few seconds for the configuration questions to appear.

Mouse, Keyboard and Video configuration
Between the ARMC/3P and the host, there are two interfaces available for transmitting keyboard and mouse data: USB and PS/2. The correct operation of the remote mouse depends on several settings which will be discussed in the following subsections.
ARMC/3P USB interface
To use the USB interface a correct cabling between the managed host and the managing device is necessary. If the managed host has no USB keyboard support in the BIOS and you have connected the USB cable only, then you will have no remote keyboard access during the boot process of the host. Please see Chapter 5: Keyboard/Mouse for more details.
C
HAPTER 3: CONFIGURATION
23
ARMC/3P Keyboard Settings
The ARMC/3P settings for the host’s keyboard type have to be correct in order to make the remote keyboard work properly. Check the settings in the ARMC/3P front-end. See Chapter 5: Keyboard/Mouse for details.
Remote Mouse Settings
A common problem with KVM devices is the synchronization between the local and remote mouse cursors. The ARMC/3P addresses this situation with an intelligent synchronization algorithm. There are three mouse modes available on the ARMC/3P.
Auto Mouse Speed
The automatic mouse speed mode tries to detect the speed and acceleration settings of the host system automatically. See the section below for a more detailed explanation.
Fixed Mouse Speed
This mode just translates the mouse movements from the Remote Console in a way that one pixel move will lead to n pixel moves on the remote system. This parameter n is adjustable with the scaling. It should be noted that this works only when mouse acceleration is turned off on the remote system.
Single/Double Mouse Mode
This mode is described in the Section called Single and Double Mouse Mode.
Auto Mouse Speed and Mouse Synchronization
The automatic mouse speed mode performs the speed detection during mouse syn- chronization. Whenever the mouse does not move correctly, there are two ways for re-synchronizing local and remote mouse:
Fast Sync
The fast synchronization is used to correct a temporary but fixed skew. Choose this option from the Remote Console Options menu (entry: Mouse Handling). If defined you may also press the mouse synchronization hotkey sequence (see Chapter 4: Remote Console Control Bar details) .
Intelligent Sync
If the Fast Sync does not work or the mouse settings have been changed on the host system, use the Intelligent Synchronization, instead. This method adjusts the parameters for the actual movement of the mouse pointer so that the mouse pointer is displayed at the correct position on the screen. This method takes more time than the Fast Sync and can be accessed with the appropriate item in the Remote Console Option menu (entry: Mouse Handling).
The Intelligent Synchronization requires a correctly adjusted picture. Use the Auto Adjustment function or the manual correction in the Video Settings panel to setup the picture.
24 P
Furthermore, the shape of the mouse pointer has a significant influence on the pointer detection. We recommend to use a simple, but common pointer shape. In most cases, the detection and synchronization of animated pointer shapes is likely to fail. In general, pointer shapes that change during the pointer detection process are rather impossible to figure out in the transferred video picture. With the usage of a standard mouse pointer shape the detection is rather simple and the syncronization is at its best.
Figure 19 Remote Console Control Bar: Sync Button
The Sync Mouse button on top of the Remote Console can behave differently, depending on the current state of mouse synchronization. Usually pressing this button leads to a Fast Sync, except in situations where the KVM port or the video mode changed recently. See also Chapter 4: Remote Console Control Bar.
Note: At first start, if the local mouse pointer is not synchronized with the remote mouse pointer, press the Auto Adjust Button once.
RODUCT USER GUIDE
Host System Mouse Settings
The host’s operating system knows various settings for the mouse driver.
Important: The following limitations do not apply in case of USB and Mouse Type “MS Windows 2000 and newer”.
While the ARMC/3P works with accelerated mice and is able to synchronize the local with the remote mouse pointer, there are the following limitations which may prevent this synchronization from working properly:
Special Mouse Driver
There are mouse drivers which influence the synchronization process and lead to desynchronized mouse pointers. If this happens, make sure you do not use a special vendor-specific mouse driver on your host system.
Windows 2003 Server/XP Mouse Settings
Windows XP knows a setting named “improve mouse acceleration” which has to be deactivated.
Active Desktop
If the Active Desktop feature of Microsoft Windows is enabled, do not use a plain background. Instead, use some kind of wallpaper. As an alternative, you could also disable the Active Desktop completely.
See also the Section Recommended Mouse Settings for mouse mode recommendations.
C
HAPTER 3: CONFIGURATION
25
Navigate your mouse pointer into the upper left corner of the applet screen and move it slightly forth and back. The mouse will be resynchronized. If resynchronizing fails, disable the mouse acceleration and repeat the procedure.
Single and Double Mouse Mode
The information above applies to the Double Mouse Mode where remote and local mouse pointers are visible and need to be synchronized. The ARMC/3P also fea­tures another mode, the Single Mouse Mode, where only the remote mouse pointer is visible. Activate this mode in the Remote Console (see Chapter 4: Remote Console Control Bar) and click into the window area. The local mouse pointer will be hidden and the remote one can be controlled directly. To leave this mode it is necessary to define a mouse hotkey in the Remote Console Settings Panel. Press this key to free the captured local mouse pointer.
Recommended Mouse Settings
For the different operating systems on the host we can give the following advice:
MS Windows NT4
NT4 supports PS/2, only. Please choose the options PS/2 mouse and Auto Mouse Speed.
MS Windows 2000, 2003, XP (all versions)
In general, we recommend the usage of a mouse via USB. Choose USB without Mouse Sync. For a PS/2 mouse choose Auto Mouse Speed. For XP disable the option “enhance pointer precision” in the Control Panel.
Note: The remote mouse is always synchronized with the local mouse if selecting the option “MS Windows 2000 or newer”.
SUN Solaris
Adjust the mouse settings either via “xset m 1” or use the CDE Control Panel to set the mouse to “1:1, no acceleration”. As an alternative you may also use the Single Mouse Mode.
MAC OS X
We recommend using the Single Mouse Mode.
OS/2
We recommend using the Single Mouse Mode.
Linux
First, choose the option “Other Operating Systems” from the the Mouse Type selection box. Second, choose the option Auto Mouse Speed. This applies for both USB and PS/2 mice.
Note: For connecting a PS/2 mouse the PS/2 system cable is required.

Video Modes
The ARMC/3P recognizes a limited number of common video modes. When run­ning X11 on the host system please do not use any custom modelines with special video modes. If you do, the ARMC/3P may not be able to detect them. We recom­mend using any of the standard VESA video modes instead. Please refer to Appendix B: ARMC/3P Video Modes for a list of all supported video modes.

Prerequisites
The ARMC/3P features an embedded operating system and applications offering a variety of standardized interfaces. This chapter will describe both these interfaces and the way to use them in a more detailed manner. The interfaces are accessed using the TCP/IP protocol family, thus they can be accessed using the built-in Ethernet adapter or a modem, too.
The following interfaces are supported:
HTTP/HTTPS
Full access is provided by the embedded web server. The ARMC/3P environment can be entirely managed using a standard web browser. You can access the ARMC/3P using the insecure HTTP protocol or using the encrypted HTTPS protocol. Whenever possible use HTTPS.
Telnet
A standard Telnet client can be used to access ay device connected to the ARMC/3P’s serial port via a terminal mode.
SSH
The ARMC/3P also offers SSH (Secure Shell) access as a secure alternative to Telnet.
The primary interface of the ARMC/3P is the HTTP interface. This is covered extensively in this chapter. Other interfaces are addressed in subtopics.
In order to use the Remote Console window of your managed host system, the browser has to come with a Java Runtime Environment version 1.1 or higher. If the browser has no Java support (such as on a small handheld device), you are still able to maintain your remote host system using the administration forms displayed by the browser itself.
Important: We recommend to install a Sun JVM 1.5.
For an insecure connection to the ARMC/3P we can recommend the following web browsers:
- Microsoft Internet Explorer version 5.0 or higher on Windows 98,
Windows ME, Windows 2000 and Windows XP
- Netscape Navigator 7.0, Mozilla 1.6 and Mozilla Firefox on Windows 98,
Windows ME, Windows 2000, Windows XP, Linux and other UNIX-like Operating Systems
In order 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 a key length of 128 Bit. Some of the old browsers do not have a strong 128 Bit encryption algorithm.

Managing the ARMC/3P with a CommandCenter
If you use CommandCenter Secure Gateway to manage your devices, then you can add your ARMC/3P to CC-SG´s management domain to enable all CommandCenter features for ARMC/3P. This includes single sign on and central user management and will allow you to operate and configure the ARMC/3P directly from the CommandCenter. Please consult your CommandCenter manual for further information on this topic.
While the ARMC/3P is managed by a CommandCenter no local access is possible. Access and Authorization will only be granted through the CommandCenter.
Releasing the ARMC/3P from managed mode should be done with the CommandCenter. Should the CommandCenter not be available for some reasons, then the ARMC/3P will automatically reenable local logins after a defined time. The administrator can then manually release the ARMC/3P from CommandCenter.
The Remote Console
General Description
The Remote Console is the redirected screen, keyboard and mouse of the remote host system that the ARMC/3P controls.
The Remote Console window is a Java Applet that tries to establish its own TCP connection to the ARMC/3P. The protocol that is run over this connection is neither HTTP nor HTTPS, but RFB (Remote Frame Buffer Protocol). Currently RFB tries to establish a connection to port #443. Your local network environment has to 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 have to be configured accordingly.
32 P
RODUCT USER GUIDE
In case the ARMC/3P 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 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.
Figure 27 Remote Console
Main Window
Starting the Remote Console opens an additional window. It displays the screen content of your host system. The Remote Console will behave exactly in the same way as if you were sitting directly in front of the screen of your remote system. That means keyboard and mouse can be used in the usual way. However, be aware of the fact that the remote system will react to keyboard and mouse actions with a slight delay. The delay depends on the bandwidth of the line which you use to connect to the ARMC/3P.
With respect to the keyboard, the very exact remote representation might lead to some confusion as your local keyboard changes its keyboard layout according to the remote host system. If you use a German administration system and your host system uses a US English keyboard layout, for instance, special keys on the
C
HAPTER 4: USAGE
33
German keyboard will not work as expected. Instead, the keys will work like their US English counterparts. You can circumvent such problems by adjusting the keyboard of your remote system to the same mapping as your local one.
The Remote Console window always tries to show the remote screen with its optimal size. That means it will adapt its size to the size of the remote screen initially and after the screen resolution of the remote screen has been changed. However, you can always resize the Remote Console window in your local window system as usual.
Important: In difference to the remote host system, the Remote Console window on your local window system is just one window among others. In order to make keyboard and mouse work, your Remote Console window must have the local input focus.
Remote Console Control Bar
The upper part of the Remote Console window contains a control bar. Using its elements you can see the status of the Remote Console and influence the local Remote Console settings. A description for each control follows.
Ctrl+Alt+Delete
Special button key to send the “Control Alt Delete” key combination to the remote system (see also Chapter 5: KVM Settings for defining new button keys).
Drive Redirection button
Menu Button for opening the Drive Redirection menu and choosing between two virtual media options at the same time (see also Chapter 5: Drive Redirection).
Note: The “Drive Redirection” window with the two drives for selection opens only if the client system is using Windows 2000 or higher and if the Remote Console user has an administrator status on Windows. In case the client system is using a LINUX OS the “Drive Redirection Selection” window will not be displayed.

Mouse Handling
The submenu for mouse handling offers two options for synchronizing the local and the remote mouse pointer as explained in Chapter 3: Mouse, Keyboard and Video configuration.
• Fast Sync The fast synchronization is used to correct a temporary but fixed skew.
• Intelligent Sync Use this option if the fast sync does not work or the mouse settings have been changed on the host system.
• Mouse Mode Use this option to choose between Single Mouse or Double Mouse Mode, see Section: Remote Console Control Bar.
Important: This method takes more time than the fast one and requires a correctly adjusted picture. To setup the picture you may use either the auto adjustment function or the manual correction in the Video Settings panel.

Important: Any message sent to the Chat will be broadcasted to all connected users, which are using the Remote Console at the time the message was sent. There is no option to direct a message to a particular user only. The Chat has no message history. That means, messages will be received only after opening the Remote Console. Messages that possibly have been sent among other users will be lost for a user who opens up his Remote Console afterwards.
Video Settings
Opens a panel for changing the ARMC/3P video settings. The ARMC/3P features two different dialogs which influence the video settings.
Video Settings through the HTML Frontend
Select this option to enable local video port. This option decides if the local video output of the ARMC/3P is active and passing through the incoming signal from the host system.
The option Noise Filter defines how the ARMC/3P reacts to small changes in the video input signal. A large filter setting 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 filter 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). All in all the default setting should be suitable for most situations.

Refresh Video
Use this option to refresh the video picture. The video data for the Remote Console is updated completely.
On startup of the Remote Console, the ARMC/3P transmits the entire video picture from the remote host. Subsequently, the parts of the video picture that did not change are filtered and not transmitted, again. This leads to less video data to be transmitted. It may happen that there are parts of the video picture that are not updated correctly (video noise, compression errors). You may use this option to initiate an entire refresh, manually.
Soft Keyboard
The Soft Keyboard simulates an entire keyboard that is connected to the remote system. It is necessary in case your remote system runs with a completely different language and country mapping than your administration machine. By selecting the appropriate button(s) you can send key codes and also key sequences to the remote system and act as if you would work with a keyboard that is directly connected to the remote system.
In order to open the Soft Keyboard select the entry “Soft Keyboard” from the Options menu. You can send single key strokes like F as well as combinations of keys such as Ctrl+C or AltGr+Shift+F4.
For a single key stroke you can click on the button with the appropriate character. Single keys such as regular characters and numbers are sent immediately. Special keys like Ctrl, Shift as well as the function keys F1 to F12 have to be selected twice. The first press sends the signal “key is pressed”, the second press sends the signal “key is released” to the remote system. After the first press the button will change its color to indicate that the appropriate key is pressed, currently. After the second press the button will appear as usual and indicate that the key was sent.
To send the key combination Ctrl+C select the button Ctrl first. The button will change its color. Press the button C. The following key (C in our example) will be combined with the previously selected key. Both the buttons Ctrl and C are released and the key combination will be sent to the remote system. The button Ctrl will appear as normal (color change).
In order to send the key combination Ctrl+F5 three steps have to be taken. Select the button Ctrl once and the button F5 twice. The last press will release both buttons and send the key combination to the remote system.
In order to send the key combination AltGr+Shift+F4 four steps are required. First, select the button AltGr once. Second, select the button Shift. Finally, choose the button F4 twice. The last press will release all the buttons and send the key combination to the remote system.

Encoding
These options are used to adjust the encoding level in terms of compression and color depth. They are only available unless “Transmission Encoding” is determined automatically (see Chapter 5: Transmission Encoding).
• Predefined This option Predefined offers optimized data for transmission. It depends on the bandwidth of the chosen connection.
Figure 38 Remote Console Options Menu: Encoding - Predefined
• Compression level You may select a value between 1 and 9 for the desired compression level with level 1 enabling the fastest compression and level 9 the best compression. The most suitable compression level should always be seen as a compromise between the network bandwith that is available, the video picture to be transferred, and the number of changes between two single video pictures. We recommend to use a higher compression level if the network bandwidth is low. The higher the compression level the more time is necessary to both pack and unpack the video data on either side of the connection. The compression quality depends on the video picture itself, e.g.
C
HAPTER 4: USAGE
43
the number of colors or the diversity of pixels. The lower the compression quality, the more data have to be sent and the longer it may take to transfer the whole video picture.
If level 0 is chosen the video compression is disabled, completely. The option Video Optimized has its advantages if transferring high-quality
motion pictures. In this case the video compression is disabled, completely and all video data is transferred via network as full-quality video snippets. Therefore, a high amount of bandwidth is required to ensure the quality of the video picture.
Figure 39 Remote Console Options Menu: Encoding - Compression
• Color Depth Set the desired color depth. You may select between 8 or 16 bit for Video Opti- mized/compression level 0, or between 1 and 8 bit for compression level 1 to 9. The higher the color depth, the more video information has to be captured and transferred.
44 P
Figure 40 Remote Console Options Menu: Encoding – Color Depth
RODUCT USER GUIDE
Note: If displaying motion pictures on a connection with low speed you may achieve an improvement regarding the video transfer rate by lowering the color depth and disabling the option “Video Optimized”. As a general result, the data rate is reduced (less bits per color). Furthermore, the ARMC/3P will not have to do any video compression. In total, this will lead to less transfer time of the motion picture.
• Lossy Toggles the Lossy filter on or off. If the filter is switched on there will be less data transmitted but no frames/pictures lost. That means a higher frame rate with fewer details.
Remote Console Status Line
The status line shows both console and the connection state. On the left the size of the remote screen is displayed.

Optimizing the Video Picture
To achieve an optimal video picture for the Remote Console follow the steps as given here:
1. Press the Auto Adjust button once (see the Section Remote Console Control Bar for details).

RODUCT USER GUIDE
2. Choose the option Video Settings from the Options Menu of the Remote Console. Press the button Reset this Mode.
Figure 43 Remote Console Video Settings: Reset this Mode
3. Again, press the Auto Adjust button once.
4. The ARMC/3P detects the video mode with 8 bits (256 colors) automatically. To improve the picture quality you may select 16 bit (True Color) from the Options Menu of the Remote Console, sub menu “Encoding”, entry “Color Depth” (see the Section Encoding for details).
5. Finally, if the the Remote Console transfer rate is too high you may do an adjustment using the Noise filter. The higher the filter level the more information is filtered from the transferred video picture (see the Section called Video in Chapter 6 for details) and the data rate is reduced.
Currently, the video picture with the best quality can be achieved with the settings “16 bit (High Color)” in the Remote Console or “LAN (High Color)” in the web frontend. This option can also be preset in Chapter 5: User Console. The sub menu “Compression” from the Options menu has no influence on the picture quality but on the data rate of the picture that is transferred to the Remote Console.
Reducing the Noise of the Video Picture
To reduce the noise from the video picture for the Remote Console you may adjust the Noise filter. Prior to that we recommend optimizing the video picture as described in the Section called Optimizing the Video Picture.
In most cases the rate of transferred data indicates the noise level. The higher the transfer rate, the higher the noise of the video picture. You may do an adjustment using the Noise filter. The higher the filter level the more information is filtered from the transferred video picture (see Chapter 5: Video details) and the data rate is reduced.

HAPTER 4: USAGE

Using the ARMC/3P with low bandwidth
The network connection of the ARMC/3P has an important influence on the time between two single video pictures. On a connection with low bandwidth it takes longer to transfer the video data from the ARMC/3P to the Remote Console on the local host. If the remote screen has changed a new picture is sent.
In terms of transfer time there is no difference between text screens and screens in graphics mode. The video picture is taken as graphics data no matter what the screen looks like and which video mode is chosen. In terms of transferred data there can be an improvement. The compression plays an important role here. You can choose a compression level from the sub menu Compression in the Options menu of the Remote Console.
Please note that the video will be compressed on the ARMC/3P, transferred to the Remote Console and unpacked in a Java environment. Depending on the remote host and on the local machine this procedure may take some time and may result in a slowly updated picture in the Remote Console.
To improve the speed you may also set the picture quality in the Remote Console to either “8 bit” or even to grayscale. Due to less video data to be processed this is likely to be more effective than the highest compression level.

RODUCT USER GUIDE
Figure 45 Power Control Overview
Internal Power Control via ATX wires
The power button is the representation of the ATX power button on your host system. It is used to switch on and off the power supply. The ATX power button knows two operation modes: pressing it shortly and pressing it for about 4 seconds.
Short Press
A short press on the ATX button is normally caught by the running operating system that tries to initiate a controlled shutdown.
Usually this should always be the first action you try in case you would like to power off your system. Only in case this is not working you should try the long press button.
Please note that after you have pressed this button the power state displayed in the administration panel will not immediately reflect the requested change. A controlled shut down of the system may take some minutes. You can observe the action caused by your button press using the Remote Console window or by reloading the Server Power Control panel.
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.
Reset
Pressing this button is similar to pressing the Reset button directly on the remote system. Be aware that pressing the Reset button will result in an unconditional and immediate cold start of the system. This might damage open files and the file system itself.

Telnet Console
The ARMC/3P firmware features a Telnet gateway that enables a user to connect to the ARMC/3P via a standard Telnet client. For connecting to the ARMC/3P via Telnet protocol you may use a terminal program such as xterm, TeraTerm or Putty. As an alternative you may also enter the telnet command on the command line or use the “Run” dialog from the Windows Start Menu. As an example you may type the following sequence:
telnet 192.168.1.22
Replace the IP address by the one that is actually assigned to the ARMC/3P. This will prompt for user name and password in order to log into the device. The creden­tials that need to be entered for authentication are identical to those of the web interface. That means the user management of the Telnet interface is entirely controlled with the comparable functions of the web interface.
Once you have successfully logged into the ARMC/3P a command line will be presented and you can enter the necessarry management commands.
In general, the Telnet interface supports two operation modes: the command line mode and the terminal mode. The command line mode is used to control or display some parameters. In terminal mode the pass-through access to serial port 1 is acti-

The specified image file is supposed to be accessible from the ARMC/3P. The in­formation above has to be given from the point of view of the ARMC/3P. It is important to specify correct IP addresses and device names. Otherwise, the ARMC/3P may not be able to access the referenced image file properly, leave the given file unmounted and it will display an according error message, instead. So, we recommend to state correct values and repeat this step if necessary.
Figure 53 The Image File on the Share
Furthermore, the specified share has to be configured correctly. Therefore, admin­istrative permissions are required. As a regular user you may not have these per­missions. You should either login as a system administrator (or as “root” on UNIX systems) or ask your system administrator for help to complete this task.

Drive Redirection
The Drive Redirection is another possibility to use a virtual disc drive on the remote computer. With Drive Redirection you do not have to use an image file but may work with a drive from your local computer on the remote machine. The drive is hereby shared over a TCP network connection. Devices such as floppy drives, hard discs, CD ROMs and other removable devices like USB sticks can be redirected. It is even possible to enable a write support so that for the remote machine it is possible to write data to your local disc.
Figure 56 Drive Redirection
Please note that Drive Redirection works on a level which is far below the operating system. That means that neither the local nor the remote operating system is aware that the drive is currently redirected, actually. This may lead to inconsistent data as soon as one of the operating systems (either from the local machine, or from the remote host) is writing data on the device. If write support is enabled the remote computer might damage the data and the file system on the redirected device. On the other hand, if the local operating system writes data to the redirected device the drive cache of the operating system of the remote host might contain older data. This may confuse the remote host’s operating system. We recommend to use the Drive Redirection with care, especially the write support.

Drive Selection
Figure 58 Selecting the desired Drive
Select the drive you would like to redirect. All available devices (drive letters) are shown here. Please note that the whole drive is shared with the remote computer, not only one partition. If you have a hard disc with more than one partition all drive letters that belong to this disc will be redirected. The Refresh button may be used to regenerate the list of drive letters, especially
for an USB stick.
Write Support
Figure 59 Selection Write Support
This feature may be enabled here. Write support means that the remote computer is allowed to write on your local drive. As you can imagine, this is very dangerous. If both the remote and the local system try to write data on the same device, this will certainly destroy the file system on the drive. Please use this only when you exactly know what you are doing.
Virtual Drive and Device Authentification
Figure 60 Device Authentification
To use the Drive Redirection, you have to authenticate on the ARMC/3P using a valid username and password. A permission to change the virtual disc configuration is necessary .
With the offered Double Virtual Media feature of the ARMC/3P you have to select the drive you want to use.

Navigation Buttons
Connect/Disconnect
To establish the drive redirection press the Connect button once. If all the settings are correct, the status bar displays that the connection has been established, the Connect button is disabled and the Disconnect button is enabled.
On an error, the status line shows the error message. The drive redirection software tries to lock the local drive before it is redirected. That means that it tries to prevent the local operating system from accessing the drive as long as it is redirected. This may also fail, especially if a file on the drive is currently open. In the case of a locking failure, you will be prompted if you want to establish the connection anyhow. This should not be a serious problem when the note above is respected. If the write support is enabled, a drive which is not locked might be damaged by the Drive Redirection.
With the Disconnect button, a connection via Drive Redirection connection is stopped.
Exit/Hide
If the Exit button is pressed, the Drive Redirection software is closed. If a Drive Redirection connection is active, the connection will be closed before the application terminates.
Using the Hide to Tray button the application is hidden, but not terminated completely. That means that an active connection will be kept active until it is closed explicitly. You can access the software by its tray icon. The tray icon also shows whether a connection is established or not. A double click on the icon shows the application window, or with a right click you may access a small menu (see Figure 62).

Creating an Image
Floppy Images
UNIX and UNIX-like OS
To create an image file make use of “dd”. This is one of the original UNIX utilities and is included in every UNIX-like OS (UNIX, Sun Solaris, Linux). To create a floppy image file copy the contents of a floppy to a file. You can use the following command:
dd [ if=/dev/fd0 ] [ of=/tmp/floppy.image ]
dd reads the entire disc from the device /dev/fd0 and saves the output in the spec- ified output file /tmp/floppy.image. Adjust both parameters exactly to your needs (input device etc.)
MS Windows
You can use the tool “RawWrite for Windows”.
Select the tab Read from the menu. Enter (or choose) the name of the file in which you would like to save the floppy content. Click on the Copy button to initiate the image creation process. For related tools you may have a look at the homepage of the fdos project (http://www.fdos.org/ripcord/rawrite/).

dd reads the entire disc from the device /dev/cdrom and saves the output in the specified output file /tmp/cdrom.image. Adjust both parameters exactly to your needs (input device etc.).
MS Windows
To create the image file use your favourite CD imaging tool. Copy the whole contents of the disc into one single ISO image file on your harddisk. For example, with “Nero” you choose “Copy and Backup”. Then, navigate to the Copy Disc section. Select the CD ROM or DVD drive you would like to create an ISO image from.

User Management
The configurable settings of the ARMC/3P are split into user settings (basically authentication and user information) and group settings (authorization).
There is one predefined user "admin" and two predefined group "admin" and "<unknown>", which cannot be renamed or deleted.
Each user may be member of one group and inherits permissions set for this group. If a user is not member of a group, permissions can be set exclusively for that user. The user “admin” is always member of admin group which has full system access. The <unknown> group initially does not have any permissions, but is modifiable.
Users can authenticate against a remote authentication service (such as LDAP or RADIUS). If this remote authentication service returns an invalid or no group assignment, the user is considered to be member of the <unknown> group.
Upon delivery, the account for the user “admin” has the password “password”. Make sure to change the password immediately after you have installed and first accessed your ARMC/3P.
A full list of available options follows. This list can only be seen by the admin.
Existing users

To create a user or a group press the Create button. The Modify button changes the displayed user settings. To delete an user or group press the Delete button.
Note: The ARMC/3P is equipped with an host-independent processor and memory unit which both have a limitation in terms of the processing instructions and memory space. To guarantee an acceptable response time we recommend not to exceed the number of 25 users connected to the ARMC/3P at the same time. The memory space that is available onto the ARMC/3P mainly depends on the configuration and the usage of the ARMC/3P (log file entries etc.). That’s why we recommend not to store more than 150 group profiles.

This selection box displays the user ID for which the values are shown and for which the changes will take effect. Select the desired user from the selection box and press the Update button. This will result in displaying the according user settings below.
Note: You are allowed to change the settings of other users only if you have the necessary access rights for this task. For a regular user without the correct permissions it is not possible to change the settings for any other users.
Transmission Encoding
The Transmission Encoding setting allows changing the image-encoding algorithm that is used to transmit the video data to the Remote Console window. It is possible
to optimize the speed of the remote screen depending on the number of users working at the same time and the bandwidth of the connection line (Modem, ISDN, DSL, LAN, etc.).
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
The pre-configured settings deliver the best result because of optimized adjustment of compression and color depth for the indicated network speed.
Manually
Allows to adjust both compression rate and the color depth individually.
C
HAPTER 5: MENU OPTIONS
71
Depending on the selected compression rate the data stream between the ARMC/3P and the Remote Console will be compressed in order to save bandwidth. Since high compression rates are very time consuming, they should not be used while several users are accessing the ARMC/3P simultaneously.
The standard color depth is 16 Bit (65536 colors). The other color depths are intended for slower network connections in order to allow a faster transmission of data. Therefore compression level 0 (no compression) uses only 16 Bit color depth. At lower bandwidths only 4 Bit (16 colors) and 2 Bit (4 gray scales) are recommended for typical desktop interfaces. Photo-like pictures have best results with 4 Bit (16 gray scales). 1 Bit color depth (black/white) should only be used for extremely slow network connections.

plug-in is not yet installed on your system, it may be downloaded and installed automatically. However, in order to make the installation possible, you still have to answer the according dialogs with “yes”. The download volume is around 11 Mbytes. The advantage of downloading Sun’s JVM is the usage of a stable and identical JVM across different platforms. The Remote Console software is optimized for this JVM version and offers a wider range of functionality when run in SUN’s JVM.
Important: If you are connected over a slow connection to the Internet you can also pre-install the JVM on your administration machine.
Miscellaneous Remote Console Settings
Start in Monitor Mode
Sets the initial value for the monitor mode. By default the monitor mode is disabled. In case you switch it on, the Remote Console window will be started in a read only mode.
Start in Exclusive Access Mode
Enables the exclusive access mode immediately at Remote Console startup. This forces the Remote Consoles of all other users to close. Nobody else can open the Remote Console at the same time again until you disable this feature or log off.
Mouse Hotkey
Allows to specify a hotkey combination which starts either the mouse synchronization process if pressed in the Remote Console or is used to leave the single mouse mode.
Remote Console Button Keys
Button Keys allow simulating keystrokes on the remote system that cannot be generated locally. The reason for this might be a missing key or just the fact that the local operating system of the Remote Console is unconditionally catching this keystroke already. Typical examples are “Control+Alt+Delete” on Windows and DOS, that is always caught, or the key sequence “Control+Backspace” on Linux that can be used for terminating the X-Server.
In order to define a new Button Key or to adjust an existing one have a look at the rules that describe the setting for a key. In general, the syntax for a key is as follows:
[confirm] <keycode>[+|-|<[*]<keycode>]* A term in brackets is optional. The star at the end means that you add further keys
as often as required for your case. The term “confirm” adds an confirmation dialogue that is displayed before the key strokes will be sent to the remote host.
The “keycode” is the key to be sent. Multiple key codes can be concatenated with either a plus, a minus, or an “<” sign. The plus sign builds key combinations - all
C
HAPTER 5: MENU OPTIONS
73
the keys will be pressed until a minus sign or the end of the combination is encountered. In this case all pressed keys will be released in reversed sequence. So, the minus sign builds single, separate keypresses and keyreleases. The “<” sign releases the last key, only. The star inserts a pause with a duration of 100 milliseconds.
As an example, the key combination of Ctrl, Alt and F2 is represented by the sequence
Ctrl+Alt+F2
For a full list of key codes and aliases please refer to the Appendix C: Key Codes.

LAN Interface Settings
This entry field displays the current settings for the Ethernet/LAN interface of the ARMC/3P. You may choose between auto negotiation and a fixed setting for the Ethernet transceiver settings “interface speed” and “duplex mode” in case auto negotiation does not work correctly.
LAN interface speed
Depending on your network connection you may select an according speed value for this interface. To adjust the interface automatically choose “autodetect” (default value). If this selection results in misbehavior of the interface, choose one of other speed options to work with. The interface will transmit and receive data with that fixed speed.
LAN interface duplex mode
If necessary you may also select a specific duplex mode. The default value is set to “autodetect” which leads to an automatic setting of the duplex mode depend- ing on your network (recommended). As an alternative you may explicitly set the interface to either “half duplex” or “full duplex” mode.
These settings may also be configured via serial console. See Chapter 3: Initial Configuration via Serial Console for details.

Dynamic DNS
Figure 79 Dynamic DNS
A freely available Dynamic DNS service (dyndns.org) can be used in the following scenario (see Figure 80 Dynamic DNS Scenario):
Figure 80 Dynamic DNS Scenario
82 P
RODUCT USER GUIDE
The ARMC/3P is reachable via the IP address of the DSL router which is dynami­cally assigned by the provider. Since the administrator does not know the IP address assigned by the provider, the ARMC/3P connects to a special dynamic DNS server in regular intervals and registers its IP address there. The administrator may contact this server as well and pick up the same IP address belonging to the card.
The administrator has to register an ARMC/3P that is supposed to take part in the service with the Dynamic DNS Server and assign a certain hostname to it. He will get a nickname and a password in return from the registration process. This account information together with the hostname is needed in order to determine the IP address of the registered ARMC/3P.
You have to perform the following steps in order to enable Dynamic DNS:
• Make sure that the LAN interface of the ARMC/3P is properly configured.
• Enter the Dynamic DNS Settings configuration dialog as shown in Figure 79.
• Enable Dynamic DNS and change the settings according to your needs
(see below).
Enable Dynamic DNS
This enables the Dynamic DNS service. This requires a configured DNS server IP address.
Dynamic DNS server
This is the server name where ARMC/3P registers itself in regular intervals. Currently this is a fixed setting since only dyndns.org is supported for now.
Hostname
This is the hostname of the ARMC/3P that is provided by the Dynamic DNS Server (use the whole name including the domain, e.g. testserver.dyndns.org, not just the actual hostname).
Username
You have registered this username during your manual registration with the Dynamic DNS Server. Spaces are not allowed in the Nickname.
Password
You have used this password during your manual registration with the Dynamic DNS Server.
Check time
The ARMC/3P card registers itself in the Dynamic DNS server at this time.
Check interval
This is the interval for reporting again to the Dynamic DNS server by the ARMC/3P.

Unblocking Users
There are two possibilties to unblock a blocked user.
• A parent user may go to the user management settings (see User Management) and press the Unblock button for the user.
• It is also possible to use the serial console for the initial configuration (see Table 4) and login as the user “unblock”. The ARMC/3P will ask for the superuser password ans present a list of blocked users which may be unblocked.

Login Limitations
Single Loging Limitation
If this option is enabled, the user can access the ARMC/3P only from one IP adress with one connection. It is not possible to access the ARMC/3P from different IP addresses or web browsers with the same login at the same time. You have to be logged out or the session has to be timed out to get a new connection on a different IP address on the ARMC/3P with this login.
Password Aging
If this option is enabled after a defined interval a reminder will request a new password for the user. The set interval displays how many days the password is active.
Certificate
The ARMC/3P uses the Secure Socket Layer (SSL) protocol for any encrypted net­work traffic between itself and a connected client. During the connection establish­ment the ARMC/3P has to expose its identity to a client using a cryptographic certificate. Upon delivery this certificate and the underlying secret key is the same for all ARMC/3P ever produced and certainly will not match the network con­figuration that will be applied to the ARMC/3P cards by its user. The certificate’s underlying secret key is also used for securing the SSL handshake. Hence, this is a security risk (but far better than no encryption at all).
However, it is possible to generate and install a new base64 x.509 certificate that is unique for a particular ARMC/3P card. In order to do that, the ARMC/3P is able to generate a new cryptographic key and the associated Certificate Signing Request
(CSR) that needs to be certified by a certification authority (CA). A certification au­thority verifies that you are the person who you claim you are and signs and issues a SSL certificate to you.

Figure 82 Certificate Settings
To create and install a SSL certificate for the ARMC/3P the following steps are necessary:
• Create a SSL Certificate Signing Request using the panel shown in Figure
82. You need to fill out a number of fields that are explained below. Once this is done, click on the Create button which will initiate the Certificate Signing Request generation. The CSR can be downloaded to your administration machine with the Download button (see Figure 83).
• Send the saved CSR to a CA for certification. You will get the new certificate from the CA after a more or less complicated traditional authentication process (depending on the CA).
• Upload the certificate to the ARMC/3P using the Upload button as shown in Figure 83.

After completing these three steps the ARMC/3P has its own certificate that is used for identifying the card to its clients.
Important: If you destroy the CSR on the ARMC/3P there is no way to get it back! In case you deleted it by mistake, you have to repeat the three steps as described above.
Common name
This is the network name of the ARMC/3P once it is installed in the user’s network (usually the fully qualified domain name). It is identical to the name that is used to access the ARMC/3P with a web browser but without the prefix “http://”. In case the name given here and the actual network name differ, the browser will pop up a security warning when the ARMC/3P is accessed using HTTPS.
Organizational unit
This field is used for specifying to which department within an organization the ARMC/3P belongs.
Organization
The name of the organization to which the ARMC/3P belongs.
Locality/City
The city where the organization is located.
