No Ethernet activity

If the Ethernet LED did flash 10 times but then went off, proceed as follows:
Procedure 8-8 Ethernet LED flashed 10 times then went out
1
Check that the RJ45 connection from the LAN port of the PIDU Plus to
the PC is working.
2 If the PC connection is working, remove and examine the cable that
connects the PIDU Plus to the LPU or ODU.
3
Check that the wiring to pins 1&2 and 3&6 is correct. For example, the
wiring to pins 1 and 3 may be crossed.
4 If this test fails, replace or repair the cable that connects the PIDU Plus
to the LPU or ODU.

Irregular Ethernet activity

The yellow Ethernet LED should blink randomly as normal traffic passes through. If
the Ethernet LED flashes irregularly, for example there is a short flash followed by a
long flash, this indicates that the ODU has booted in recovery mode. The causes may
be installation wiring or a corrupt ODU software load. For more information, see
recovery mode

If the Ethernet connection to the network is only 10/100 BaseT, when 1000 BaseT is
expected, proceed as follows:
