Abstract: A method of creating an IT-network representation including automatically discoverable active elements and not automatically discoverable, passive elements. A logical discoverable-elements representation of the IT network is produced, by running a network auto-discovery tool. The representation includes the automatically discoverable active elements and a discoverable-elements network topology. Representations of not automatically discoverable elements are manually inserted, by a user by means of a network-element editor, between automatically discovered elements into said discoverable-elements representation. Thereby a combined logical representation is created which models the IT network with its automatically discoverable elements and non automatically discoverable elements.

Abstract: An underfloor cable junction unit for installation in a raised-floor system used as cooling air supply duct for devices arranged on the raised floor and having floor panels with cooling air outlets has a top side. The top side or at least a major part of it is open to enable the passage of cooling air through the top side toward a floor panel with cooling air outlets.

Abstract: A system for tracking cables is disclosed includes a cable socket and a radio frequency identification (RFID) tag placed near an end of at least one of the cables, where the end of the at least one cable is configured to be inserted into the cable socket. The system also includes a reader device having at least one antenna positioned near the cable socket and being configured to transmit a radio frequency (RF) signal to interrogate the RFID tag and thereby track the cables.
