5.4 Troubleshooting of MPU Card
S12800 routing switch supports two MPU card (control card) slots. If two MPU cards are
inserted, one is active and the other is standby. In the normal working state, the SYS indicator
on the MPU card panel is in the flashing state. If the SYS indicator is off or on, it indicates that
the MPU card is faulty. Please refer to the following steps for troubleshooting.
Step 1:
Check whether the power module works normally. For details, refer to

.
Step 2:
Check whether the MPU card is installed well. You can pull out the MPU card and
insert in again to ensure that the MPU card is installed well. After the MPU card
is started, view whether the SYS indicator of the MPU card flashes.
Step 3:
Insert the MPU card to another MPU card slot and view whether the working
state is normal. If yes, it indicates that the previous MPU card slot may be
damaged.

the configuration terminal.
If the fault still cannot be located by the preceding steps, please contact the agent or local
technical service engineers.
