Abstract

An administrator station for administering and maintaining a plurality of computer network and/or communications servers. A low profile clam-shell display and keyboard apparatus, as utilized in a portable notebook computer, is used to replace a rack mounted cathode ray tube video monitor, keyboard and cursor control devices, and an electromechanical switcher. An interface apparatus translates the video output, keyboard and mouse signals of a plurality of computer servers to a format that may be communicated to the administrator station either through a physical connection or by means of wireless communications such as infrared, cellular or spread spectrum radio. When not in use, the administrator station may be stored in a low profile rack panel located in a rack cabinet having a plurality of computer servers mounted therein. Alternatively, the administrator station may be moved from one rack cabinet of computer servers to another. The administrator station may also be comprised of a standard computer, either portable or desk top, and use a wireless or wired communication means adapted to communicate with a plurality of computer servers in different locations.
