Press any other key to abort the Manual Scan. NOTE: The Scan Type setting will determine whether computers must be eye-marked to be included in the scan.
Chapter 5 How to Remotely Control the Host Computer(s) A. Accessing the VNC Interface There are three ways to communicate with the Digital KVM via IP in order to control the host computer(s). Web interface: The integrated Web server includes a Java-based VNC client. This allows easy browser-based remote control. II. Native VNC client: There are several third-party software programs that use the standard VNC protocol, available in open source and commercial VNC clients. III.
You may need to upgrade or download your Java (http://www.java.com) support in your browser before using the VNC screen to remote control the host computer(s); however, most modern browsers come with a version of Java that is compatible with this application. The Java VNC client makes a connection back to the KVM control over IP module over port 5900 (by default) or 15900, if encrypted.
B. Using the VNC Menu One of the unique features of this product is the VNC menu system. Whenever you see a window with a dark blue background and grey edges, this window has been inserted into the VNC data stream so that it is effectively laid over the existing video. These menus allow you to control the many features of the Digital KVM via IP without using the web interface or a custom client. Welcome Window When you initially connect to the system, a window similar to the above one will be shown.
Bandwidth: Indicates current average bandwidth coming out of the Digital KVM via IP. The second number measures round trip time (RTT) of the connection when it was first established. Resync: Re-aligns the remote and local mouse points so they are on top of each other. Redraw: Redraws the entire screen contents; occurs immediately. Video Adjust: Adjusting the video phase automatically. PS/2 Reset: Resets the PS/2 keyboard and mouse emulation.
PS/2: This area will show PS/2 (as in this example) to indicate if keyboard and mouse are PS/2 signals. If Autosync appears beneath this indicator, the mouse pointers on the local mouse and the VNC session will be synchronized automatically. [1][A][S]: These flags show the state of the keyboard lights, NumLock, ShiftLock and ScrollLock respectively. Other items: If the server's screen is larger than 1024x768, additional buttons will be shown to the right of the above listed items.
Take Control: When multiple users are connected to the same system, use this button to take control away from another user. Only one user may control the keyboard and mouse at any time. All users see the same picture. Thumbnails: Switch to smaller thumbnail size screen images (click anywhere on thumbnail to restore it). Each button corresponds to a different sized image, from half size to one-sixteenth. Logout: End the VNC login session and disconnect.
F. How to Use the Video Tuning Menu This menu is used to fine-tune the video picture. Auto Everything: use this button to automatically fine-tune all three adjustments. If the test pattern for Color Offset calibration is not present on the screen, then the Color Offset adjustment is skipped. Changes/frame: it indicates the number of 16x16 blocks of video that are being sent, on average, for every frame of video. With a static image being displayed by the server, this number will be zero (shown as -nil-).
Appendix A Troubleshooting If you are experiencing trouble with your devices, first make sure that all cables are connected to their proper ports and are firmly seated. How to bring up the IP-OSD menu? Please use your paperclip or pen to press the “IP SETUP” button once to bring up the IP-OSD menu.

Appendix G Using Optional Serial Supervisor Module (IPMI supported) with the R-Port (For DS-11215, DS-13215, DS-14215 only) Background The Digital KVM via IP offers a unique way to expand the functionality of the base product. Using RPort on the rear panel of Digital KVM via IP, you can add up to 16 Serial Supervisors serial devices using a specialized daisy-chain technology.
#: You can assign a value (1 ~ 99) to each attached serial device. This does not affect the configuration or operation of the device in any way, but is simply a means to sort this list for ease of management. Name/Description: An identifier for the Serial Supervisor device. assignment, it is for ease of administration only. Like the number Baud (bps): This is the communication speed for the device, and the setting here must match the setting on the device itself (see below).
You are now connected to the Serial Supervisor device. Commands you type will be echoed on the terminal screen. It offers a simple menu system that allows you to change its configuration settings. To access the menu press Ctrl + Shift + Space (underscore) on the keyboard to access the menu.
IPMI (Intelligent Platform Management Interface) Function Background To offer a more complete remote server control solution, the DIGITAL KVM VIA IP offers an optional power management feature that allows remote hardware restarts and the ability to power the host computer on and off. You may be able to take advantage of this feature if the host computer you are managing supports IPMI (Intelligent Platform Management Interface).
Have your model and serial number on hand. When asked, supply the technician with the code listed under Purchase Options at the bottom of the Firmware and flash memory management page. Once the order is processed, the technician will provide you with an Unlock code. Enter that code in the space provided, and click Submit. The system will update itself to allow IPMI configuration.
You will be presented with the IPMI Status menu (see above). Make the following changes to enable IPMI: Enable IPMI (Intelligent Platform Management Interface) via serial port: select Enabled. Select which serial port to use: select Front serial port (DTE pin out) since the Digital KVM via IP has DTE serial port only. Select baud rate to use: select a value from the menu between 9600 bps and 115,200 bps based on the configuration on the host computer’s IPMI settings.
From the VNC interface: click IMPI from the Bribar at the bottom of the VNC window Examples: VNC Status Report Accessing IPMI Controls There are two ways to access power controls for the managed computer. The first is through the Home screen on the Web interface. The second is through the Bribar during an active VNC session.
Once IPMI is enabled and functioning correctly, a set of controls will appear immediately under the thumbnail image of the host computer on the Home screen on the Web interface. NOTE that you must be logged in as admin to use this feature. From here, you have four options: Hard Reset: Equivalent to pressing the RESET button on the managed computer. The computer will restart.
Appendix H Using Optional Modem Feature λ Background The modem option allows the Digital KVM via IP to act as an Internet connection server for increased security and flexibility in connecting with the managed computers. Unlike the TCP/IP connection used with the standard Web configuration and VNC clients, the modem creates a one-to-one connection between the Digital KVM via IP and the computer you are using to manage your network that is essentially private, as it bypasses the public Internet completely.
λ Connecting a Modem The Digital KVM via IP will work with virtually any Hayes-compatible modem that recognizes the standard AT command set.
Init string: leave as ATE0S0=1&K3 (see below). The baud rate dictates the connection speed between the Digital KVM via IP’s serial port and the modem, and does not affect the connection speed between the local and remote modems, as they will negotiate their own connection speed when a connection is made. It is highly recommended that this setting be left at the default for best performance.
• • • • • PPP (Point-to-Point Protocol) must be used; no other authentication methods are supported. TCP/IP must be installed/enabled on the computer making the connection, and must be used for the dial-up connection. The connection must be configured to obtain a dynamic IP address. The user name/password must match a user currently configured on the Digital KVM via IP. For best performance and to simplify the troubleshooting process, firewall software should not be used with the dial-up connection.
Modem init chat script failed The modem did not respond to the initialization string from the Digital KVM via IP. You may need to change the init string or verify the cabling and modem status. Modem init okay The modem has responded appropriately to the init string. Saw PPP startup from client A PPP authentication has occurred and a session has started. Phone line rings! An incoming call has been detected by the modem.
