3.
Select a CS as the Master CS and press that CS's RESET switch.
The Master CS will flash red and green alternately, and other CSs (Slave CSs) will flash amber.
4.
After one hour, the color of the LEDs on Slave CSs indicates the diagnosis results.
Color
Diagnosis Result
Green
Completed successfully
Red
Completed unsuccessfully
Amber
Can be used under certain conditions
5.
If the LED of the CS is red or amber, connect the CS to a hub that has a CS with a green LED connected,
or a hub that has no CSs connected, and turn on the CS.
6.
If necessary, repeat the above procedure.
If repeating the procedure does not fix the problem, reconfigure the network according to
"5.3 Recommended Network Configuration", or consider air synchronization instead of LAN
synchronization.
If the result is still undetermined, a long-term diagnosis will start in the background automatically. The result
of this diagnosis can be obtained via IP Terminal Maintenance Console. Also, temporary results can be
obtained every hour by checking the LEDs.
For details about IP Terminal Maintenance Console, refer to "5.12 IP Terminal Maintenance Console".
Note
•
The CS set as the Master CS in advance diagnosis mode should be the first CS registered to the PBX
so that it becomes the Master CS in regular operation.
•
Long-term diagnosis can also be started by setting DIP switches. For details about setting the DIP
switches, refer to "Time Required for Long-Term Diagnosis" in "5.2 DIP Switch".
Long-term Diagnosis
1.
Turn on DIP switches no. 4 and no. 8 for each CS.
2.
Specifies the time required for long-term diagnosis by using DIP switches no.1-3, refer to "5.2 DIP
Switch".
3.
Connect each CS in turn to a nearby hub. If the hub does not support PoE (Power over Ethernet), connect
the CS to a power outlet using the AC adaptor.
During the diagnosis, the LED flashes green. If the LED flashes red or amber, a temporary result of
"Completed unsuccessfully" or "Undetermined result" has been reached.
4.
After 24 hours, the color of the LEDs indicates the diagnosis results.

hours in IP Terminal Maintenance Console.
For details about IP Terminal Maintenance Console, refer to "5.12 IP Terminal Maintenance Console".
