11.3.2 Post‐Power Testing
Connect the RJ45 to the 30/60 Mbps PIDU and apply power. The power LED should be
illuminated continuously. If the power LED does not illuminate unplug the ODU connection
from the 30/60/Mbps PIDU and check the power LED illumination. If the power LED still
does not light then check the power source.
The Ethernet LED should be observed starting with 10 slow flashes, 30 seconds after
powering. This confirms that the ODU has the correct power connections, if the Ethernet
LED does not light check the wiring to pins 4 & 5 and 7 & 8.
If a computer, switch or router is connected to the LAN side of the 30/60 Mbps PIDU then
the Ethernet LED should flash with network activity. If the Ethernet LED does not show
Ethernet activity then the network equipment and the Ethernet cables need to be checked,
specifically continuity through to the ODU of pins 1 & 2 and 3 & 6.
