Product Features

  • Single-user KVM switch provides server management—plus USB keyboard and mouse support.
  • Enables a single USB keyboard and mouse user to access eight CPUs.


  • Supports a wide range of IBM® compatible computers, including PS/2® and PC/AT® keyboards and mice.
  • Compatible with our ServSwitch.
  • Flash upgradable via the serial port.
  • High-quality video resolution with DDC support.
  • Password security.
  • On-screen menus provide easy switching. Or switch from the front panel, with hotkeys, or from a three-button mouse.
  • Cascadable to support more CPUs.
  • Supports a three-button mouse or IntelliMouse®.
  • Are you looking for exceptional server management capabilities in a single-user KVM switch? Then take a look at the ServSwitch Uno USB. It's perfect for the IT professional who wants flexibility but doesn't require multiuser or remote access.

    The ServSwitch Uno USB gives you access to eight CPUs or servers. It supports the USB interface, so you can use the latest keyboards and mice.

    Use alone or cascade.
    Use this switch to control 8 CPUs. Or string multiple switches together to control hundreds of servers. It's also compatible with the ServSwitch Duo, ServSwitch Duo USB, and ServSwitch Quadro for use in large installations.

    The autoscan feature makes monitoring CPUs or servers easy. Scan only the active CPUs or servers attached to one chassis, or scan selected CPUs or servers attached to any chassis in your system. You can even program your preferred scan rate and view each CPU or server at your own pace.

    Easy switching.
    KVM switching isn't an unwieldy operation either. On-screen menus pop up on demand and make it easy to select a CPU or server. You can even give each CPU or server a name that makes sense to you. No software is required on your CPUs or servers because their names are stored in both switches' memory.

    You can also switch between CPUs or servers using a front-panel push button, a hotkey sequence, or a three-button mouse.

    Lock out unauthorized users.
    Set up individual user profiles with separate passwords. You can control who can access each CPU or server. For extra security, lock the front-panel controls.

    A selectable screen-saver mode puts the switch to sleep and blanks the screen after a set period of inactivity. Plus, the switch automatically locks itself when it goes into sleep mode.

    Plays well with others.
    Compatibility is no problem. The switch supports a wide range of PC-compatible hardware and software platforms, including some high-end IBM® PS/2 compatible computers such as IBM RS/6000®, Compaq®, Alpha®, and SGI™. It works with both PC/AT serial and PS/2 mice and keyboards. Automatic mouse conversion means they work with all PS/2, IntelliMouse, and RS-232 mice. The ServSwitch Uno USB also works with USB keyboards and mice.

    The switch handles mouse communications in the stream mode used by desktop PCs and in the prompt mode used by laptops such as the IBM ThinkPad® so you can use it with nearly any IBM compatible laptop.

    Installation options.
    Use standard CPU Cables (EHN408) to connect PS/2 CPUs. For PCs or Sun® computers with USB connections, use PS/2 to USB Flash Cables (EHN428).

    With PS/2 to Sun Flash Cables (EHN429), you can access legacy Sun CPUs with 8-pin connectors. Macintosh® connections vary widely—to get the right cables for your Mac® application, call our FREE Tech Support.

    To connect workstations to your switch, just use the cables that came with your keyboard, monitor, and mouse.
