Problem Possible Solutions
The POWER LED is off
Make sure the power cable connector is properly seated in
the B-FOCuS O-4F2P power input.
Verify that the power adapter is plugged into a live AC
outlet.
Check the power cable for shorts or breaks.
Check the status of the POWER Button. If it is lit in red,
push and release the button to turn on the power.
Disconnect the power input connector at the B-FOCuS O-
4F2P and use a voltmeter to verify that the proper voltage
level is present on the 12 V pin (power and power return)
from the power adapter.
The ALARM LED is red
flashed or in red solid
Power cycle the B-FOCuS O-4F2P by unplugging it from
the power adapter, then plugging it back in. If the B-
FOCuS O-4F2P fails the self test a second time, replace
the unit.
The OPTICAL LED is in
red solid
Check the optical path.
Reset the B-FOCuS O-4F2P by reset button. If the B-
FOCuS O-4F2P fails again, replace the unit.
The OPTICAL LED is
always green flashed
This is normal at boot-up and may take up to 1 minute to
turn green. If this state persists, contact the NOC
(Network Operation Center) to verify that the B-FOCuS
O-4F2P serial number, password, and vendor ID match
those provisioned in the network database.
If provisioning is correct, have the NOC determine
whether there are alarms on the PON feeding the B-
FOCuS O-4F2P. If no alarms exist, use an optical power
meter to troubleshoot the fiber network.
The UPDATE LED is in
red solid
Contact NOC.
The POTS LED is off
when telephone off-hook
Check the telephone connection, or voice service is
disabled. Contact NOC for verification.
