Abstract
An adjustable-voltage Power-over-Ethernet (PoE) switch provides data signals and output electrical powers to a multiple number of output PoE ports. The adjustable-voltage PoE switch has an output voltage-adjusting interface, allowing a user to select a specific power level or a specific output voltage for the particular output PoE port. The adjustable-voltage PoE can also include a conventional IEEE 802.3af-compliant power mode for further utilizing PoE in communicating and powering up external devices. A plurality of light indicators corresponding to the multiple number of output PoE ports provides further convenience by indicating a specific power level or a specific output voltage for a particular output PoE port using a particular color in each color-changing light indicator.
