Fault Finding
133
Differentiating between 1-3 and 4 can be achieved by removing the power for 1 second. Watch
the Ethernet indicator for 1 minute while power is removed, if it never flashes then the problem is
1-3. Take the jumper (J905) out of the PIDU Plus and check the current taken by the ODU. This
should be 300mA to 1A when starting to run normally.
If the Ethernet indicator flashes to begin with but then stops flashing, the 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.

10 seconds from power on

Off while switch pressed. Approximately 30 seconds
after releasing the switch, flashes twice per second
regularly for 10 seconds, then boots in “Recovery
Mode” While in “Recovery Mode” the unit will only
be accessible via the IP address 10.10.10.10 or
169.254.1.1.

Checking your wiring
If the above procedures fail to diagnose the issue you may have a wiring fault. Unplug the RJ45
from the PIDU+ and check the following resistances at the RJ45:
1. Check the cable resistance between pins 1 & 2, 3 & 6, 4 & 5 and 7 & 8 at the RJ45.
2. Check against column 2 in
. Resistances for each pair should be within 1 ohm of each
other.
