PITTSBURGH, PENNSYLVANIA, April 1, 2008 - Black Box Corporation, provider of more than 118,000 networking products, introduces the ServSwitch - Secure (with USB) (SW2007A-USB, SW4007A-USB), two TEMPEST approved USB KVM switches that enable users to safely switch between secured and unsecured networks as well as those with multiple security classifications.

These high-security KVM switches feature individual I/O processors with high levels of port isolation, fully separating data on public and private networks. What's more, software tools and applications cannot be used to access any connected computer from another. Users can safely switch among as many as four computers operating at different classification levels.

The ServSwitch Secure (with USB), available with two or four ports, is built for today's USB computers. Both models feature unidirectional signal transmission so USB data cannot leak back through the switches. Plus, they prevent hacking via timing analysis, Trojans that might be stored on attachable USB drives, and forced overloads. The two switches feature heavy-duty, electronically bonded metal cases that ensure low emissions to minimize snooping risks.

Both switches also support DVI-I video, which is already differential, DC balanced, and encoded for security. Additionally, DVI-I video provides exact video quality and is backwards compatible with analog VGA monitors. The switches also offer true DDC video support, which can be disabled for installations requiring the highest security.
