Interface Module Failure; Interface Failure - H3C CR16000-M Installation Manual

1. Verify that the power system is operating correctly. For more information, see
failure".
2. Remove and reinstall the MPU to make sure it is installed securely.
3. Press the reset button on the MPU to reset the MPU. After the MPU is reset, verify that the RUN
LED is on.
4. If the router has an empty MPU slot, install the MPU in the empty MPU slot, and verify that the
MPU can operate correctly.
5. If the issue persists, contact H3C Support.

Interface module failure

When an interface module is operating correctly, the RUN LED on it flashes at 0.5 Hz.
Symptom
The RUN LED on an interface module is off or steady red.
Solution
To resolve the issue:
1. Verify that the MPU is operating correctly. For more information, see
2. Verify that the interface module is compatible with the system software. Upgrade the system
software if it does not support the interface module.
3. Calculate the total power consumption, and make sure a sufficient number of power supplies
are installed. For more information, see H3C CR16000-M Routers Hardware Information and
Specifications.
4. Ensure that the interface module is installed securely. Remove the interface module, reinsert it
into the slot, and then rotate inward the ejector levels until ends of the ejector levers touch the
front panel of the interface module tightly.
5. If the router has an empty interface module slot, install the interface module in the empty
interface module slot. If the interface module operates correctly, the previous slot is faulty.
6. If the issue persists, contact H3C Support.

Interface failure

MPUs and interface modules provide a LED for each interface. The LED is on if the interface is
operating correctly.
NOTE:
A management Ethernet port has two LEDs, LINK and ACT. When the LINK LED is off, the
management Ethernet port fails.
Symptom
The LED for an interface is off.
Solution
To resolve the issue:
1. Make sure the MPU or interface module where the interface resides operates correctly. For
more information, see
2. Verify that the cable is connected correctly for the interface. For information about how to
correctly connect a cable to an RJ-45 interface, "Connecting a twisted pair cable." For
