The SV841HDI empowers you to securely manage up to 8 computers remotely from almost anywhere using your LAN or the Internet. Unlike software solutions that require installation and work through your server's operating system, the SV841HDI gives you BIOS level control and full interaction with your system's boot process . Control does not come at the expense of security: SSH tunneling, SSL encryption, RADIUS authentication, and a configurable firewall are all included to ensure that your network stays secure. With both USB and PS/2 support, this switch easily handles a mixed platform environment to provide a central point of administration for all your servers. For added flexibility you can attach your existing KVM switches to the SV841HDI to remotely control up to 64 computers, and its standardized 1U rack-mountable metal chassis allows easy installation in your rack or cabinet.
