PoE-Plus Capability: 30W High Power
In addition to IEEE802.3af standard, Korenix also supports IEEE802.3at pre-standard high power PSE solution for PDs which power requirements are greater than 15.4W. JetPoE switch series delivers up
to 30 watts of high power, which can be used in high end demanding applications.

Forced Powering
Korenix provides advanced forced powering control to deliver power to those non-standard PoE devices
that cannot be detected as valid PD’s. In the early days PoE products that were circulating the market
prior to the ratification of PoE standard 802.3af did not comply with the current standard and did not
support PD detection and classification. The PoE switch cant recognized the PD, thus, it will not
forward the power. The forced powering ability solves this problem and enables all your PD’s

Manual Power Limitation
Korenix allows users to manually configure the power limitation of the attached PD that doesn’t support PD
classification. This can be used to prevent over-power drawing by a non-standard PD and also provides over-heat protection in the event that power forwarding has been exceeded.

Redundant Power Supply
Korenix supports power input redundancy on your PSE, flexible solutions for those applications where a reliable power supply is critical. The backup power input will be enabled when the main input fails.
