ETHERNET DEVICE CAPABLE OF INDICATING STATUS AND METHOD THEREOF

摘要

A method for an Ethernet device indicating a number of states in relation to electrical power available and the good or bad status of electrical connections detects connections between terminal devices and connection ports of the Ethernet device. An indication unit displays no indication signal in the absence of any connection and detects the good or bad status of any connections which are detected. If a connection is bad, the indication device is controlled to produce an indication signal but in the absence of any bad connections, obtains and quantifies a residual power of a power module to determine the number of terminal devices which the Ethernet can be deemed able to support, the different numbers of supportable terminal devices being indicated by different signals.

主权项

1. An Ethernet device capable of indicating status, comprising:
a power module configured to provide power; a plurality of connect ports configured to connect to different types of terminal devices; an indication unit; a processing unit configured to control the indication unit to produce indication signal; and a power management module connected to the power module, the plurality of connect ports, the indication unit, and the processing unit, and configured to distribute power from the power module to the plurality of connect ports, the processing unit, and the indication unit, and to detect a residual power of the power module; wherein, the processing unit is further configured to obtain residual power of the power module detected by the power management unit, and determine a quantity of the terminal devices that can be powered by the residual power of the power module, to control the indication unit to produce a first indication signal after determining that the quantity of the terminal devices can be powered by the residual power of the power module is not greater than one, and to control the indication unit to produce a second indication signal after determining that the quantity of the terminal devices can be powered by the residual power of the power module is greater than one.
