4. Installing the Converter 
 
4.1 POE120 converter connected to a Power Sourcing Equipment
Device (PSE) 
 
1. Connect the copper cable to your IEEE 802.3af compliant PSE device.
The POE120 can also work as a standard media converter and 
connect to a non POE device. (power supply is optional) 
 
2. Connect the fibre cable to your connecting device.
 
Note: 
- Please make sure that the 802.3af power is being supplied from a PSE
device to the PD Media Converter.
- In case there is no 802.3af PSE available or the PSE device power
fails, you may install an AC-DC adapter as a backup solution. Do not 
connect the PSE Copper port and a AC-DC adapter at the same time. 
(the power options are not designed in a redundant configuration)
