Power over Ethernet
Power over Ethernet is one of the key features of the ES7510-XT. The ES7510-XT is IEEE 802.3af and IEEE
802.3at compliant. The ES7510-XT supports up to eight PoE injectors ports, each port with the ability to
deliver 30W of power.

PoE Control
In WiMax systems, wireless applications, and high-end PoE applications, there are various types of powered
devices (PDs). To be compatible with different PDs, the ES7510-XT is designed with four powering modes,
including:
•
IEEE 802.3af mode
•
IEEE 802.3at 2-event mode
•
IEEE 802.3at LLDP classification mode
•
Forced powering mode to meet any PD type
The ES7510-XT supports Managed and Unmanaged Power Budget modes.
•
Managed Power Budget mode: If you select Managed for the Power Budget, the ES7510-XT uses port-b
ased
rules and priorities to manage PoE output power budget.
•
Unmanaged Power Budget mode: If you select Unmanaged for the Power Budget, the ES7510-XT disables
rules and system controls. The Power Budget fields are disabled.
IEEE 802.3at LLDP provides smart power budget control behavior to fulfill the needs of higher end setups
requiring exact high power delivery. By using the ongoing dynamic re-negotiation function of the IEEE
802.3at LLDP, the ES7510-XT can perform more intelligently by dynamically reallocating power to the PDs.
The ES7510-XT implements the 2 event and Link Layer Discovery Protocol (LLDP) PoE into the system for
efficient power budget negotiation between the PSE and the PDs.
The ES7510-XT also provides PD Status Detection. This provides automatic detection of a remote device
powered by the ES7510-XT. If the remote system crashes or is unstable, the ES7510-XT performs a system
reboot by turning off and on again to trigger the remote device.

If Forced mode is selected, power is provided even if no Ethernet cable is plugged in. Only use Forced mode
if you are attaching a device that is capable of receiving power through its Ethernet connection.
