Link down
Link down
(operational
down) on one of
the Ethernet
interfaces
Line interfaces
(eth1,eth2,eth3,eth4):
1) Ethernet cable
disconnected or not
connected properly.
2) Ethernet interface
disabled (admin down).
3) Port settings mismatch
4) Interface HW fault.
Radio interface (eth0):
1) Low receive signal (due
to antenna mis-alignment
or rain fading).
2) Mismatch in rf
configuration between
sides or wrong
configuration.
3) Interference.
4) HW fault.
Line interfaces
(eth1,eth2,eth3,eth4):
1) Verify cable terminated and
connected properly.
2) Verify port configuration,
including auto-neg and
speed/duplex.
3) Replace ODU.
Radio interface (eth0):
1) Improve antenna alignment
and verify clear line of sight.
2) Verify RF configuration.
3) Change channel to verify no
interference.
4) Replace ODU.
Link Up
Link up
(operational up
on one of the
Ethernet
interfaces
Link down state cleared
and interface is up
(operational).
Link restored, no corrective
actions needed.
Modulation Change
RF link
modulation
changed to the
specified
modulation
profile
In adaptive mode:
Modulation changed (up
or down) due to change in
link RF link conditions.
In static mode:
Modulation changed
manually or when link
changed state to up or
down.
Verify if modulation change is
due to rain fading, mis-
alignment or interference.
1) Improve antenna alignment
and verify clear line of sight.
2) Verify RF configuration.
3) Change channel to verify no
interference.
4) Replace ODU.

1) Verify air-flow not
obstructed.
2) Verify ODU is installed in
