STROMVERSORGUNG EINER ETHERNET-KARTE DURCH EIN ENDGERÄT ODER EIN LOKALES NETZWERK (LAN)

摘要

The card has a control module for controlling a coupling module and connected logically to main and auxiliary supply modules. The control module controls the coupling module to electrically decouple an internal bus (PCI2) from an internal bus (PCI1) to permit the card to operate independent of a micro-computer (UE) when the card is supplied by the auxiliary module and the computer is not supplied by the main module.
