    1. Product Overview Introduction ComboXCAT-IP redirects local keyboard, mouse and video data to a remote administration console. It allows you to control one or many computers locally at the server site or remotely via the Internet using a standard browser. You can securely gain BIOS level access to systems for maintenance, support, or failure recovery over the Internet.

  • Page 8: When Controlled Servers Are Up And Running

    When Controlled Servers are Up and Running ComboXCAT-IP gives you a full control over the remote servers. The Management Console allows you to access the remote servers' graphics, keyboard and mouse and to send special commands to the servers.

    Default IP address: 192.168.0.70 Default Net Mask: 255.255.255.0 If DHCP mode is enabled (IP auto configuration = DHCP), ComboXCAT-IP 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.
  • Page 10 DHCP server. It is recommended to configure a fixed IP assignment to the MAC address of ComboXCAT-IP. You can find the MAC address labeled on the bottom side of the metal housing. There is a Network Setup Software tool (ComboXCAT-IP-Setup) for setting up the network configuration (IP address, Subnet mask, DHCP, etc).

    3.3.5 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. ComboXCAT-IP also features another mode, the Single Mouse Mode, where only the remote mouse pointer is visible.

  • Page 17: Video Modes

    ComboXCAT-IP recognizes a limited number of common video modes. When running X11 on the host system, please do not use any custom mode lines with special video modes. If you do, ComboXCAT-IP may not be able to detect them. We recommend using any of the standard VESA video modes, instead.
