1. Connect the RJ45 to the PIDU and apply power to the PIDU, the power LED should illuminate
continuously.
2. 30 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.
If the system does not operate corrctly, refer to the fault finding below.
The PIDU Green power LED does not illuminate
Unplug the ODU connection from the
PIDU and check the power LED illumination. If the power LED still does not light then check the
power source.
The PIDU Green power LED flashes
A flashing power LED indicates that there is a short
circuit on the output of the PIDU. Check that pins 4&5 and 7&8 are not crossed with pins 1&2
and 3&6 on the RJ45, and also greater than 100K ohms between pins 1&8.
The Ethernet LED flashes ten times but does not show Ethernet activity
Failure of the
Ethernet LED to show Ethernet activity can be due to wiring to pins 1&2 and 3&6 being incorrect,
for example if the wiring to pins 1 and 3 are crossed.
The Ethernet connection to the network is only 10/100BaseT, when 1000BaseT was
expected
It is likely there is a fault with the wiring to pins 4&5 and 7&8.
