Fault 2: The AC power module does not work.
[Fault Description]
The Status LED of each line card is OFF, the Power LED of the fan tray is OFF, and the fan does not work.
The LED on the panel of the power module is OFF. The fan does not work.
[Troubleshooting]
First place the switches of all the power modules to OFF. Check if the cables of the cabinet have been correctly connected.
Check whether the power cables are tightly connected to the cabinet power sockets and power modules. Check whether
the power modules are installed correctly. If necessary, pull out the power modules and check whether the connectors on
the backboard of the power system are tightened.
Fault 3: An exception occurs to the LEDs when line cards are powered on.
[Fault Description]
The Status LED of the line card is OFF, blinking, or RED. The Link/ACT LED of the line card is solid ON when no network
cable or fiber is plugged.
[Troubleshooting]
Check if the line card is firmly inserted. If so, install the line card again and ensure that it is inserted into position before
you tighten the fastening screws. If the line card still does not work, check if the connector of the slot on the backplane is
loose. If yes, insert the board to another slot for a try. If the slot and connection are not the cause, return the line card for
repair.
Fault 4: The LED is abnormal after a line card works for some time.
[Fault Description]
The Status LED of the line card is OFF or RED. The Link/ACT LED of the line card is solid ON when no network cable or
fiber is plugged. The fault remains after restart.
[Troubleshooting]
Check if the board gets loose. If so, install the line card again and ensure that it is inserted into position before you tighten
the fastening screws. If the line card still does not work, check if the connector of the slot on the backplane is loose and
check if the guide rail of the slot is deformed. If so, insert the board to another slot for a try. If the slot and connection are
not the cause, return the line card for repair.
Fault 5: The LED of the management board is abnormal.
[Fault Description]
The LED of the management board becomes abnormal after the board is powered on or works for some time. For
example, the Status LED is blinking or OFF, and the Alarm LED is red.
[Troubleshooting]
Check if the management board gets loose. If so, install the management board again and ensure that it is inserted into
position, before you tighten the fastening screws. If the management board still does not work, check if the connector of
the slot on the backplane is loose and check if the guide rail of the slot is deformed. If yes, insert the board to another slot
for a try. If the slot and connection are not the cause, return the management board for repair.
When the Alarm LED is red, the cause may be the fault of another module in the system, in which case you can check
other modules (for example, line card, fan, power, and overheating) for any alarm. If yes, you should first handle the faults
of other modules. You can also identify the faults by logging in to the management software.
Fault 6: The fan tray does not work.
[Fault Description]
After the system starts, the fans in the fan tray do not work or the Power LED is OFF.
[Troubleshooting]
Check if the connection between the fan tray and the backplane is secure and if the connector gets loose. If the
connection is secure, you need to replace the fan tray.
Fault 7: The serial port console has no output.
