1. There is no power reaching the ODU because of a wiring fault
2. The ODU is faulty
3. The PIDU is faulty
4. The Ethernet network side is faulty
Look at the following table to check the LED response for power up, disconnect the power and
reapply and note what happens.
Differentiating between 1--3 and 4 can be achieved by removing the power for 1 second. Watch
the Ethernet indicator for 1 minute, if it never flashes then the problem is 1—3. Take the jumper
(J906) out of the 30/60 Mbps PIDU and check the current taken by the ODU. This should be
300mA to 1A when starting through to running normally.
If the Ethernet indicator flashes to begin with but then stops flashing then ODU is powered and
software loaded but Ethernet connectivity has been lost between the ODU and the users
connected equipment. All Ethernet connections should be rechecked.
