ServSwitch Duo USB KVM Switch - 2 x 16

16 multiplatform servers can be accessed by 2 users with USB-style keyboards and mice.


Please call 877-877-2269 for a replacement product or part.
Extended Double Diamond™ Warranty Available (3 Additional Year)

Product Features

  • Supports Sun® USB-style keyboards and mice.
  • High video resolution support. Maximum resolution is 1920 x 1440 @ 100 Hz.
  • DCC support.
  • Can be cascaded with the ServSwitch Duo.


  • Built-in DDC support.
  • On-screen menus enable easy switching.
  • You can also switch ports via a three-button mouse, an IntelliMouse, hotkey sequences, or the front-panel push buttons.

  • USB keyboard and mouse users can access and control up to hundreds of servers with these KVM switches!

    With a ServSwitch Duo™ USB, 2 users can access 16 servers—or up to hundreds of servers—if you daisychain multiple ServSwitch Duo USB units together or in series with multiple ServSwitch Uno™, ServSwitch Uno USB, or ServSwitch Duo!

    Built-in DDC support.
    DDC support enables a control station's monitor to communicate with the attached servers' video cards and configure their video drivers automatically at bootup.

    The ease of on-screen menus.
    On-screen menus pop up on demand and make it simple to select a server. Give each server a name that makes sense to you. No software is required on your servers; their names are stored in the switch's memory.

    Plus, you can use the on-screen menus to control who can access each server. Set a user's level of access to exclusive use, shared use, or video only.

    Select servers at your fingertips, too.
    You can also switch between servers via a three-button mouse, an IntelliMouse®, hotkey sequences, or the front-panel push buttons.

    More compatibility than the basic Duo.
    Like the basic ServSwitch Duo, the ServSwitch Duo USB 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™.

    However, the ServSwitch Duo USB also works with USB keyboards and mice. Plus automatic mouse conversion means they work with all PS/2, IntelliMouse, and RS-232 mice. You can even mix both styles in one installation!

    For connecting remotely to your server room over IP, add the ServSwitch Wizard™ IP (ACR2004A) to control PC, Sun®, and Mac® servers.

    Scan servers at your own pace.
    Monitor all connected servers with autoscan. You can also scan only active servers attached to one chassis or selected servers attached to any chassis in your system. Program your preferred scan rate and view each server at your own pace.
