5.
If the router has empty fabric module slots, install the module in an empty fabric module slot. If
the module operates correctly, the previous slot is faulty.
You can install fabric modules only in slots 10 to 15.
6.
If the issue persists, contract H3C Support.
Interface module failure
Symptom
The RUN LED on the 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 your power supplies can provide
enough power. For more information, see
H3C CR19000-8 Core Router Hardware Information
and Specifications
.
4.
Remove and reinstall the interface module to make sure it is installed securely. For more
information about installing an interface module, see "Installing interface modules."
5.
If the router has empty interface module slots, install the interface module in an empty interface
module slot. If the interface module operates correctly, the previous slot is faulty.
You can install interface modules only in slots 0 to 3 and slots 4 to 7.
6.
If the issue persists, contact H3C Support.
Interface failure
Symptom
The LED for the interface is off.
NOTE:
A management Ethernet port has a LINK/ACT LED. When the LINK/ACT LED is off, the
management Ethernet port fails.
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 how to correctly connect a cable, see
"Connecting cables."
3.
Verify that the cable is in good condition. Use the cable to connect two interfaces of the same
type that operate correctly. If the LEDs of the two interfaces are on, the cable is in good
condition. If the LEDs are off, the cable is faulty. Replace the cable.
4.
If the interface uses a transceiver module, perform the following tasks:
a.
Make sure the transceiver module is compatible with the interface and the cable.
b.
Replace the transceiver module.
5.
Verify that the speed and duplex settings of the interfaces on the two ends are the same.
