A keyboard/video/mouse (KVM) switching protocol is disclosed in which KVM information is applied to a network of workstations. At least one data converter communicates on the workstation network and retrieves KVM information from the workstation network that is addressed to a server assigned to the converter. The converter places the KVM information in a format suitable to the assigned server and applies the converted KVM information to the appropriate standard device ports of the server. The system provides motherboard access to the servers that is characteristics of KVM switches but provides essentially unlimited scalability not known in traditional KVM switches.

Network based KVM switching system

An apparatus, method, and system for providing control, status, and security functions in a peripheral switch for connecting one or more computers to one or more user stations. Information from a remote terminal is transferred on a network in a packet where the switch information in the packet uses a standardized management protocol. When the packet is received by a network interface card in the peripheral switch the switch information is translated to a proprietary protocol. The peripheral switch then responds to the switch information by performing a control function, providing status information to the remote terminal, or by changing security information. In addition to the transfer of peripheral information from the remote terminal, the peripheral switch is capable of transferring switch information from one of the user stations.

A data communication system 10 has a controller 14 for managing the system. A controller backup unit (CBU) 24 contains configuration information for the controller 14. If controller 14 is replaced, the new controller 14 obtains the configuration information from the CBU 24.
