Power over Ethernet-prioritized active splitter
First Claim
1. A network for providing both data transmission and electrical power to hardware devices connected over the network, comprising:
- a plurality of network hardware devices connected over the network, wherein the network provides both data transmission and electrical power from a main electrical power supply to the plurality of network hardware devices, the network hardware devices comprising high priority network devices that are more critical devices of the network and low priority network devices that are less critical devices of the network;
an uninterruptible power supply (UPS) coupled to the network to supply electrical power over the network to the network hardware devices in the event of a failure of the main electrical power supply;
at least one prioritized active splitter coupled between the network and at least one low priority network device, the at least one prioritized active splitter providing electrical power from the UPS over the network to the at least one low priority network device with a low priority level and disconnecting the at least one low priority network device from receiving electrical power from the network in the event of a failure of the main electrical power supply, to reduce the power load on the UPS, with the high priority network devices remaining connected to receive electrical power from the network.

Abstract
A POE (power over Ethernet)-prioritized active splitter is disclosed for a prioritized network having different priorities such as a network security system that uses an intelligent POE power supply with a prioritized back-up response, allowing a lower cost UPS (uninterruptible power supply) system to be used, and also providing a longer back-up time period by the UPS system for more critical components of the security system. A simple embodiment operates with only two priority levels, a high priority level for more critical components of the, such as the cable modem, the system router, fire alarm devices, local warning devices and the alarm communicator, while less critical components are supplied with electrical power at the low priority level. In the event of a power outage or disconnection, the critical high priority components remain connected to the Ethernet network to be supplied with electrical power by the UPS system and also to communicate over the twisted wire pairs of the Ethernet network.
