    Get some distance.
    The ServSwitch Duo has a built-in local extender, so if you want to connect a keyboard, monitor, and mouse up to 656.1 feet (200 m) away, just order the Receiver (Remote) Module (ACU5011A). The ServSwitch Duo has one RJ-45 port. Both the local and remote ports share server access on a timeout basis.

    Up-front and personal switching.
    On-screen menus make these switches exceptionally easy to use. The 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 because their names are stored in the switches' memory. You can also switch between servers via on-screen menus, a three-button mouse, an IntelliMouse, hotkey sequences, or the front-panel push buttons.

    Good in crowds, and very friendly.
    This switch handles large installations, too. Daisychain it to control hundreds of servers!

    Compatibility is no problem either. It 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®.

    The ServSwitch Duo works with PC/AT serial and PS/2 mice and keyboards. Automatic mouse conversion means it works with all PS/2, IntelliMouse, and RS-232 mice. You can even mix both styles in one installation. Sun compatibility is available using EHN428 for USB and EHN429 for legacy support.

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

    Keep an eye on your servers.
    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.

    More good stuff.
    Standard connectors enable the use of ordinary PC cables for close connections of only a few feet. If you want more robust signaling and ease of use, we recommend our economical Control Station Cables.

    The ServSwitch Duo supports PC keyboard modes 1, 2, and 3, making them compatible with all PC/AT® and PS/2® style keyboards.

    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.
