Possible Cause Judgment Criterion Troubleshooting Method
A rogue ONU (such as a
continuous-mode ONU)
exists on the network and
affects other ONUs.
NOTE
If a rogue ONU exists, the
ONU that fails to go online
may be a normal one and
the ONU that can go online
may be a rogue one.
If either of the following two
situations occurs, a rogue ONU
exists.
l The 0x2e314021 There are
illegal incursionary rogue
ONTs under the port
alarm is generated on the
OLT.
l The 0x2e314022 The ONT
is rogue ONT alarm is
generated on the OLT.
l Connect the optical fiber of
the OLT port to the optical
power meter for
measurement. If a value can
be read from the optical
power meter, a continuous-
mode ONU or irregular-
mode ONU exists.
Replace the rogue ONU with a
normal one.
The information (SN) for
ONU authentication
conflicts; hence, the
power-on ONU fails to
go online.
The 0x2e305015 The
authentication information
of the ONTs conflicts alarm is
generated on the OLT.
Replace the ONU with
conflicted SN.
The ONU hardware is
faulty.
If either of the following two
situations occurs, the ONU
hardware is faulty.
l The LEDs of the ONU are
off when the ONU is
powered on.
l After the ONU is replaced
with another ONU, the new
ONU is auto discovered by
the OLT.
Replace the faulty ONU or the
optical module of the ONU.
