ServSwitch Wizard (Rear-Access Chassis), 2-Port

A professional 2-port desktop KVM switch designed with your laptop in mind.


Please call 877-877-2269 for a replacement product or part.

Product Features

  • Control two PS/2® computers with just one PS/2 keyboard, PS/2 mouse, and VGA monitor.
  • 1600 x 1280 maximum resolution.
  • Push button, hotkey, or mouse switching.
  • Great for users requiring access to desktop computers and laptops.


  • Plug-and-play—no configuration required!
  • Space-saving design eliminates desktop clutter in small office/home office (SOHO) environments.
  • Supports Microsoft® Windows® operating systems.
  • To enable push-button switching away from the keyboard and mouse, order the optional Remote Control Module (see "Related Products").
  • Front-panel LED makes the active port easy to identify.
  • The AutoScan function enables port scanning at 2- to 60-second intervals.
  • Supports all standard VGA resolutions from 640 x 480 to 1600 x 1280.
  • Supports standard keyboard layouts of up to 104 keys and Microsoft IntelliMouse® or compatible mice.
  • Provides robust keyboard and mouse emulation to prevent lockups.
  • Supports burst/prompt mode, making it compatible with laptops.
  • Switch between a mix of PCs, including desktop PCs, laptops—even Sun—with the ServSwitch Wizard™ (Rear-Access Chassis).

    Switching is easy: Switch locally using the switch's front-panel push button, a hotkey sequence, or a three-button mouse. You can also switch remotely through the serial port using a serial device or by ordering an optional ServSwitch Remote Control Module.

    Compatible with all types.
    The adaptable ServSwitch Wizard (Rear-Access Chassis) includes built-in PS/2® and PC/AT® compatibility with support for Microsoft IntelliMouse plus support for both both burst-mode and prompt-mode mouse communications. The switch automatically restores keyboard and mouse states when channel is changed.

    The ServSwitch Wizard is compatible with all popular PC operating systems. It's also compatible with laptops that have USB connectors, IBM® ThinkPad® notebooks with "Y" cables, IBM RS/6000®, Compaq® Alpha®, SGI™, and Sun computers. When your system expands, you can cascade multiple units to control up to 64 computers!

    The sharpest image.
    The ServSwitch Wizard (Rear-Access Chassis) features 1600 x 1280 video resolution at 100 Hz to support even your high-end monitors. Support for Display Data Channel (DDC/DDC1/DDC2) PC-to-monitor communications ensures that your video cards are always "on the same page" as your monitor. You can even pair two ServSwitch Wizard switches to control computers with dual-video outputs (for details, contact our FREE Tech Support).

    Low-cost switching, high-end features.
    The ServSwitch Wizard (Rear-Access Chassis) features flash memory that makes future firmware upgrades a snap. Plus this switch is secure—password security prevents its unauthorized use.

    Cable it up!
    Make computer connections by using standard PC-style connectors. The ServSwitch Wizard (Rear-Access Chassis) has built-in variable scanning and supports extended-distance computer connections.

    To connect a PS/2 computer, order our coax PS/2 Computer Cable (EHN408). To connect an IBM compatible computer with USB connectors, choose the PS/2 to USB Flash Cable (EHN428). (You can also use the EHN428 cable to connect to a Sun computer with USB connectors.) To connect a Sun computer with an 8-pin mini DIN keyboard and mouse connector, order the PS/2 to Sun Flash Cable (EHN429).

    In most applications, the ServSwitch Wizard (Rear-Access Chassis) can draw all the power it needs from its attached computers. However, for cascading, high-end video, or for use as a video-only switch, you may need a supplemental power supply (PS649-R2).
