    Installation Device Connection 1. Connect the USB keyboard, mouse, and VGA monitor to the console connectors on the IP KVM Switch. 2. Connect a Cat5 Ethernet cable to the LAN port. 3. Power up the monitor followed by the IP KVM Switch. The IP-OSD menu should come up automatically.
  • Page 10 Select the “Network Setup Wizard” and press <Enter> to go to the next menu. The IP KVM can have its IP address assigned dynamically, or it can be given a fixed IP address. If you are unaware of the IP address, obtain it from the network administrator.

  • Page 11: Mouse Setting (Optional)

    Mouse Setting (optional) Many operating systems offer a feature called mouse acceleration that allows the user to adjust the responsiveness of the cursor on the screen to the physical movements of the mouse. While this is usually a beneficial interface enhancement, it can interfere with the operation of the unit and should be disabled on the managed computers before a remote session is attempted.

  • Page 12: Using The Web Interface

    Using the Web Interface The Web interface is the most intuitive way to configure the IP KVM Switch, offering a Java-based VNC client that can be used to control the host computer from a remote location, as well as support for any industry-standard HTML Web browser. You can access the Web interface by opening your Web browser and entering the IP address of the IP KVM Switch you wish to access/configure.

  • Page 13: Web Interface Introduction

    Web Interface Introduction After the initial login screen, the Name screen is divided into several sections, a number of which will remain on the screen at all times while viewing the Web Interface: Name: At the top of the screen, the name of the machine being controlled is displayed Main Menu: At the left-most side...

    Snapshots: The Snapshots screen allows you to view and save a screenshot of the controlled computer in its current state. This screenshot will update periodically (automatically). Saved image files are stored in PNG format. Logout: Clicking on Logout will terminate your Web Interface section. To re-initiate the Web Interface, you will be required to re-enter your username and password.

CD-ROM Mode: The IP KVM does not store any data in this mode. Instead, it emulates a USB CD-ROM drive with a disk inserted.

  • Page 16: Network Configuration

    If the host computer’s BIOS supports USB boot devices, it is possible to boot from the emulated CD-ROM or floppy - allowing complete operating system replacement without any on-site intervention. The first step is getting a bootable disk image onto the emulated floppy or CD-ROM. For CD-ROM images, you will need an .ISO image from a disk that contains special bits to enable booting (“El Torito”...

  • Page 19: Compatibility

    The Compatibility menu offers features that may provide enhanced functionality with certain KVM and power products, such as StarTech.com’s Remote Power Switch (PCM8155HNA). These can be left at their default values if you are not connecting the unit to a KVM or power management device.

  • Page 23: Using The Terminal Interface Via Serial Port

    Using the Terminal Interface via Serial Port The terminal interface can be accessed via the serial port (or through SSH using the setup command) for configuration of the basic settings of the IP KVM. While not intended to be a substitute for the Web interface, it does allow you to configure some of the same functions.

    • The port number “15900” is arbitrary in the above example and can be any number (1025...65535). It is the port number used on your client machine to connect your local SSH instance with the VNC client. If you want to tunnel two or more systems, you will need to use a unique number for each instance on the same SSH client machine.

    • KVM: Sends the KVM “hotkey” sequence. This function is only enabled when you have configured the unit to expect a particular brand of KVM downstream. It sends the key sequence to launch the KVM’s on-screen display (OSD) menu. This button is only present when a KVM model is selected in the Web interface.
  • Page 27 The main menu window may be moved by clicking and dragging on the title bar. It can be closed by pressing Escape, or by clicking on the red X in the top right corner. Here is a guide outlining various fields from the Main Menu. Most of the functions operate immediately.

    Optimizing video performance Choose the best video mode • We recommend using 60Hz refresh rate and 1024 x 768 resolution. Using a smaller resolution like this allows you to fit multiple windows on your remote desktop. Higher refresh rates stress the video card’s quality and do not provide any additional information or benefit.

    Hotkey Menu When you hit the left <CTRL> key twice within two seconds, the Hotkey Menu appears displaying a list of hot-key commands if the option is On. The Hotkey Menu can be turned Off, if you prefer not to see it when the left <CTRL> key is hit twice. The non-volatile memory stores the Hotkey Menu setting.

  • Page 37: Changing Your Configuration

    Selecting a Computer To select a computer by hot-key command you need to know the device’s channel address, which is determined by the KVM connection. For a computer connected to the switch, the address is represented by the PC port number (1~4). For example, to access the PC plugged into port 4 of the Master KVM switch, type: left <Ctrl>...

    Can I prevent the warning from occurring? Yes. You have two options that may prevent the warning from occurring. First, if the Web browser you are using offers the option to ignore the warning for future visits, the browser will no longer generate a warning if that option is selected. Second, if you install the certificate from the IP KVM onto the host computer (see below) and if the unit is configured with a domain name ending in .com, .net, .org, .gov, .edu, .us, .ca, .uk, .jp, or .tw (i.e.
