The benefits of PoE are numerous from both a network efficiency standpoint as well as a cost standpoint. Consider some of the following benefits: Flexible and more efficient network designs, simplified, faster, and lower cost installations, eases and accelerates adds, moves, and changes or temporary deployments, enables centralized power management. There are getting more and more advanced functions in IP camera, such as PTZ, IR…etc., it means that the device needs to consume more power. The standard 802.3at can provide maximum 30W power output; there should be smart design to enable the power device to allocate the power with the most efficient arrangement.

IEEE 802.3at can provide maximum 30W power output. ORing’s PoE+ switch features intelligent power managed functions, including power scheduling and power device alive checking. In addition, it also supports IEEE 802.3at high power output and LLDP MED features.

IEEE has been listening to the concerns that expressed by the PoE user community and is currently working on defining a new standard — often referred to as HiPoE, PoE+, or PoE Plus — that will support the needs of more advanced technologies.

The foremost difference from the current standard is the proposed near-doubling of power that can be distributed over the network to enable devices that require more current to benefit from PoE. In particular, the new IEEE 802.3at specifications call for delivering 30 watts of power via two twisted pairs — a significant boost from the previous standard. Even going beyond 30 watts using all four twisted pairs has been discussed as a potential future revision on the new standard. Some of the other proposed improvements include backwards compatibility with IEEE 802.3af devices. IEEE 802.3at also proposes embedding intelligence via a newly defined data link layer (layer 2) protocol. This Link Layer Discovery Protocol (LLDP) will allow the power source equipment to discover devices on the network and communicate with those powered devices to enable dynamic allocation of power levels and even putting a device in sleep mode.

Power schedule function is a great benefit to our earth and has contribution in making the planet greener by setting the power schedule around the clock. The users can set the desired power policy accordingly. For example, the factory wireless PoE access point only need to be powered on during work hours. Thus the network administrator can enable the power output from 6 AM to 10 PM and disable the power output from 10 PM to 6 AM.

ORing’s managed/lite-managed PoE Switch could be configured to monitor the real-time status of connected power devices (P.D.s). ORing’s managed/lite-managed PoE Switch could send alive-checking packets to assure the connected P.D.s are in working state. If the connected P.D.s fail to response, ORing’s managed/lite-managed PoE switch could reactivate the connected P.D.s to assure the reliability of the network.
