Abstract
An Uninterruptible Power System (UPS) powered by Power over Ethernet (PoE) is equipped with a power sourcing equipment (PSE) supplying a direct current (DC) voltage to a powered device (PD) through Ethernet cables, and an Ethernet switch which includes a packet switching controller including a central processing unit (CPU) controlling the ON/OFF states of at least one pair of DC voltage output and the onset of an initialization process of the PSE; the Ethernet switch further includes a non-volatile memory storing a firmware which provides a reboot process of the CPU such that when the UPS powered by PoE is undergoing the reboot process, the PSE can continue to supply the DC voltage. A first parameter PersistentPoE and a second parameter PPoE_flag are used for setting the ON/OFF states of DC voltage output of PoE.
