A VoIP switch includes a first input Ethernet port configured to receive electrical power from a first power sourcing equipment, and a second input Ethernet port configured to receive electrical power from a second power sourcing equipment. The VoIP switch may be configured such that the first input Ethernet port is powered by the first power sourcing equipment concurrently with the second input Ethernet port being powered by the second power sourcing equipment.
