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.
