11.3  Testing Your Installation 

If you have followed the above instructions you will have wired your system to the following 

diagram: 

 

11.3.1 Pre-Power 

Testing 

Before plugging in the RJ45 to the PIDU check the impedances at the RJ45 as described in 

11.3.2 Post-Power 

Testing 

The Correct Operation is as follows 

1. Connect the RJ45 to the PIDU and apply power to the PIDU, the power LED should 

illuminate continuously. 

2. 45 seconds after powering, the Ethernet LED should be observed starting with 10 slow 

flashes. 

3. If there is a network connection the Ethernet LED will then show Ethernet activity. 

Failure of the Ethernet LED to illuminate can be due to wiring to pins 4&5 and 7&8 being 

incorrect, for example if the wiring to pins 4 and 7 are crossed.
