Faults Indicated with LEDs

Begin troubleshooting at the ONT by checking to see if all LEDs are in their normal state,
shown in Table
on the SFU circuit board. If the LEDs are in their normal state, refer to "LEDs in Normal State"
on page 41. If the LEDs are in a fault state, refer to "LEDs in Fault State" on page 41.

LEDs in Normal State

If the LEDs are in the normal state but you are still having problems, perform the following
troubleshooting steps:
1.If the trouble is of a random or intermittent nature, check for loose or broken connections
2. If the trouble is solid, remove the Customer Provided Equipment (CPE) wiring and

LEDs in Fault State

Descriptions of each LED are listed in Table
conditions. A flow chart for troubleshooting the problem for each fault condition is provided
in "ONT Trouble Isolation".

ONT Trouble Isolation

This section describes how to isolate problems based on faults reported through LEDs:
• "UPS Power LEDs" on page 42
• "Network Status LED Off" on page 42
• "POTS Troubleshooting" on page 43

9 on page 39. There are separate LEDs for each Ethernet RJ‐45 jack that appear
at the common mounting platform.
perform the following tests:
• POTS tests described in "Test for POTS Line Faults" on page 39.
• Ethernet tests described in "Provision Ethernet Interface at OLT" on page 40. Verify the
OLT can run and pass the loop‐back tests for the Ethernet port.
If the above tests are successful, the indication of the trouble is directed back toward the
CPE wiring/equipment.
