6  NTU POWER CONCEPT 

Each NTU is fed via the power supply Molex connector on the rear panel with 48 VDC.  The NTU 
converts these voltages to its onboard supply with its DC/DC converter. 
In  case  of  a  failure  of  the  NTU's  onboard  power  supply,  all  LEDs  on  the  front-panel  will  be 
extinguished. 
Units which support remote power can be powered remotely via xDSL. In case of remote powering 
wetting current acceptance should be switched off (remove jumpers -see figure below).
