Troubleshooting list

For I2C communication and
MOSFET failure, BC dumps
EEPROM log.
For FPGA configuration failed,
BC may rebooting again and
again.
If 1 fan fails, BC will move to fan
table C.
If 2 fan fails, BC will move to
fan table D and fan will rotate
on 100% PWM.
If 1 fan fails, BC will move to fan
table C.
If 2 fan fails, BC will move to
fan table D and fan will rotate
on 100% PWM.
Troubleshooting list
Root cause
1 MAC address missed or
incorrect.
2 Ethernet link is down.
3 Wrong fan table file.
4 FPGA image is wrong.
5 FPGA configuration failed.
6 Mosfet failed.
7 I2C communication failed.
1 or more than 1 fans become
absent from left group of 6 fans
(fan no: 1~6).
1 or more than 1 fans become
absent from right group of 6 fans
(fan no: 7~12).
1 MAC address missed or
incorrect.
2 I2C communication fail.
Different Infrastructure property
between BC and MC (G5/G5.5).
Different Infrastructure property
between IM and MC (G5/G5.5).
Different Infrastructure property
between IM, MC and BC (G5/
G5.5).
Troubleshooting step
1 Check HTPB.
2 Check G5.5 FW version in
IM/MC/BC.
3 Check "llcDebug" command.
1 Ensure fan table and FPGA
image s correct.
2 LAN connection is fine.
3 Ensure MAC address is
correct and present.
4 Ensure there is no HW
damage.
Ensure all fans insert in fan wall
properly.
Ensure all fans insert in fan wall
properly.
1 Set MAC address using
llcDebug command if its
incorrect or missed.
2 Ensure there is no HW
damage.
Ensure both BC and MC have same
Infrastructure property.
Ensure both IM and MC have same
Infrastructure property.
Ensure IM, MC and BC have same
Infrastructure property.
