Post-Power Testing - Motorola PTP 600 Series User Manual

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.
If the above does not happen, possible causes may be
The 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 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 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.
The Ethernet LED flashes ten times but irregularly
Irregularly flashing, seen as a short gap followed by a long gap, indicates that the ODU has
booted in recovery mode. This may be due to either the installation wiring or a corrupted main
code image in the ODU.
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 10/100 BaseT, when 1000 BaseT was
expected
It is likely there is a fault with the wiring to pins 4&5 and 7&8.
