connected properly to the unit.
Verify that the AC plug of the power cable is
connected properly to the mains power outlet.
Replace the IDU.
Verify that the IDU-ODU cable is connected
properly.
Try replacing the IDU. If the problem persists, try
replacing the IDU-ODU cable. If the problem
persists, try replacing the ODU.
If connected directly to PC-use a straight cable.
Otherwise-use a crossed cable. If the problem
persists, try replacing the cable.
If a hub or switch is installed between the PC and
the CPE, verify first the Ethernet connection integrity
between the hub/switch and the PC by checking the
Ethernet LEDs at the hub/switch and at the PC's
NIC card. If not ok, try replacing the cable.
Verify that the IDU-ODU cable is in order and
connected properly. Using SAU, verify that PWR
LED is on and ALRM LED is off.
Try replacing the IDU. If the problem persists, try
replacing the IDU-ODU cable. If the problem
persists, try replacing the ODU.
