Powering Up

Single-Port Power Over Ethernet Adapter User’s Guide 2-3

Powering Up

Simply plug one end of the power cord or power supply into the 
unit, and the other end into a grounded AC power source. Units 
are typically connected to a power strip or other power outlet 
that may be cycled on and off. An uninterruptible power supply 
(UPS) may be used.

Power-up Sequence

Upon power‐up, all 3 LEDs will light for 2 seconds, as part of the 
self‐test for the internal microprocessor software. After the end of 
the 2 seconds, the “ON” LED will illuminate green, signifying 
that the DC output voltage is available for powering a compliant 
load (to the 802.3af PoE standards).
