2.7.1 PoE Power Rating and Forwarding Specification
This section describes power forwarding capabilities of the LPS1000. In IEEE 802.3af
standards, it specifies 15.4 watts of power budget for a powered device system. In many
applications, 15.4 watts is not sufficient to power the more demanding PoE equipment. The
LPS1000 is designed to support high power output, up to 100 watts of total power and up to 30
watts of PoE power per port at 48VDC. The following information reflects important PoE
power forwarding capabilities of the LPS1000.

WARNING
•
THE LPS1000 IS DESIGNED TO SUPPLY UP TO 100 WATTS OF TOTAL POWER AT
THE RATED 70ºC TEMPERATURE SPECIFICATION. OPERATING THE LPS1000
OUTSIDE OF THE TOTAL POWER AND TEMPERATURE MAY HINDER THE POWER
DEVICE OPERATING AND/OR DAMAGE THE LPS1000 DEVICE.
•
POWER OVER ETHERNET DEVICES NOT RATED TO BE POWERED OVER CAT5, 5E,
OR 6 CABLES SHALL NOT BE USED WITH THE LPS1000.
•
PLEASE USE CAT5 OR HIGHER RATED CABLES TO ENSURE POWER RATED
POWER LEVELS ARE DELIVERED TO THE POWERED DEVICE.
•
DO NOT EXCEED THE POWER FORWARDING CAPABILITY OF THE LPS1000.
DOING SO MAY RISK OPERATING THE LPS1000, POWERED DEVICE, AND POE
CABLES AT HAZARDOUS LEVEL. IT MAY ALSO CAUSE FIRE DANGER. INSCAPE
DATA IS NOT RESPONSIBLE FOR DAMAGES CAUSED TO THE POWERED DEVICE
