    Expand your system.
    Switch between four servers from a single console. To expand your switching platform to include additional servers, simply cascade units in a master-slave configuration to control up to 16 servers. The ServSwitch EC KVM Switch is plug-and-play, so you can add or subtract servers almost as quickly as you can plug and unplug cables.

    Eight-port and 16-port models are also available, as are other models for PS/2 and/or USB switching; see the "Similar Products" tab for details.

    Tight quarters.
    Ideal for applications where you have a limited amount of space, the 1U-high ServSwitch EC KVM Switch can be used on the desktop or mounted in a rack or cabinet.

    To save more space, the keyboard, monitor, and mouse circuitry is concentrated in a single HD15 connector at the server end. This way, you have fewer cables to install when making server connections.

    Very switchable.
    A simple yet well-designed on-screen display makes these switches very easy to use for managing server connections. You can assign 14-character server names that make sense to you.

    Switch between servers using front-panel buttons or hotkeys. Or you can let the switch do it automatically with its autoscan function. The ServSwitch EC KVM Switch will scan and switch between servers, one by one, at an interval that you determine. When autoscan detects any keyboard or mouse activity, it suspends the scanning until activity stops, and then resumes with the next computer in sequence.

    Set it and forget it.
    System settings and name entries are stored in nonvolatile memory so you don't have to worry about a power outage wiping out your information. The ServSwitch EC also saves your keyboard settings for each server and restores them when you come back to that machine.

    Check it.
    The front panel includes port LEDs, which light with the corresponding active port when you switch between servers. You can also use the on-screen display to view the connection status on each port and lock servers from unauthorized users.

    Digital quality.
    With video enhancement technology that ensures superb quality and resolutions up to 1920 x 1440, the ServSwitch EC KVM Switch is DDC2B compatible, so it can be used with the latest digital monitors. What's more, the switch is operating-system independent and transparent to all applications.
