Troubleshooting
IMPORTANT:
The barcode stuck on the router chassis contains production and servicing information. Before you return
a faulty router for serving, provide the barcode information of the router to your local sales agent.
MPU failures
RUN LED is off
When the RUN LED of the MPU is off, it indicates that the MPU is powered off or faulty. For more
information about the RUN LED, see " Appendix C LEDs ."
To troubleshoot the MPU failure:
1. Check whether the MPU is plugged in a right slot.
{
An RPE-X1 MPU must be plugged in slot 0 or slot 1.
{
An RSE-X1 MPU must be plugged in slot 1 or slot 2.
{
An MCP-X1/X2 must be plugged in slot 1 or slot 2.
2. Check whether the router is powered on normally. A green POWER LED indicates that the router
is powered on normally.
3. If the cause cannot be located in the steps above and the problem persists, contact your local sales
agent.
RUN LED fast flashes
Five minutes after the router is powered on or the MPU is plugged into the router, if the RUN LED of the
MPU still fast flashes at 8 Hz, it indicates that the MPU application program fails to start or the MPU is
faulty.
To troubleshoot the MPU failure:
1. Verify that the terminal display is correct.
2. Verify that the application program file properties are correct in the BootWare menu.
3. If the cause cannot be located in the steps above and the problem persists, contact your local sales
agent.
ALM LED is steady on or flashes
If the ALM LED of the MPU is steady on or flashes, it indicates that the router is faulty.
For example, the ALM LED is on when the system is over-temperature. In this case, the system displays the
following output:
