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
10.1.3.
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.
The Ethernet LED does not flash 10 times
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.
