Is the passive filter relay connector connected?
Is a passive filter normal?
Is jumper setup of outdoor I/F P.C. board correct?
(Jumpers 7, 8, 9 ON)
Is there no disconnection of communication line
between IPDU and I/F P.C. board?
Is communication connector between IPDU
and I/F P.C. board connected?
Is there voltage fluctuation between
4 and 5 pins of CN600 on I/F P.C. board.
(Measurement by tester: DC0 to 5V, 5 pin GND)
Is the electric fuse of a
Power supply P.C. board for FAN normal?
F500 10A 250V~
Is there voltage fluctuation between
3 and 5 pins of CN600 on I/F P.C. board.
(Measurement by tester: DC0 to 5V, 5 pin GND)
Is the output voltage of a
Power supply P.C. board for FAN normal?

3. TROUBLESHOOTING (Passive Filter Circuit)
n Diagnosis procedure for each check code
<SMMS Series (A03-009, A04-008) >
Check code name
[L29] / [CF]
(d07 / AI-NET)
Check code name
IPDU quantity error
Cause of operation
1. Incorrect model setup in service for I/F P.C. board
2. Communication error between IPDU, fan IPDU and I/F
3. IPDU, fan IPDU, I/F P.C. board error
4. Passive filter error
Sub-code:
01: IPDU1 error 02:IPDU2 error
03: IPDU1, 2 error 04:Fan IPDU error
05: IPDU1, fan IPDU error 06:IPDU2, fan IPDU error
07: All IPDU error, Disconnection of communication line between IPDU-I/F P.C. board,
“I/F control P.C. board” error, “Power supply P.C. boad for FAN” error, “Passive filter” error
