Interface Failure - H3C S12500 Installation Manual

When the two LEDs are not in the states mentioned above, the switching fabric module fails. Follow these
steps to troubleshoot the switching fabric module:
Check that the MPU works properly. For more information, see
Step1
Use the display device command to check whether the software version is compatible with the switching
Step2
fabric module in the current slot. If the software version is incompatible with the switching fabric module,
upgrade the software to a compatible version.
Calculate the overall power consumption, and make sure that your power supply can provide enough
Step3
power.
Check whether the switching fabric module is fully seated. You can unplug the switching fabric module,
Step4
plug it again, and make sure that the switching fabric module is fully seated.
If the switch has empty switching fabric module slots, plug the switching fabric module into an empty slot,
Step5
and check whether the switching fabric module can work properly.
If the failure still exists, contact the local agents or technical support engineers.
Step6

Interface failure

Both the MPU and LPU provide the LINK LEDs indicating the interface status. When the link of an
interface is present and works properly, the corresponding LINK LED is on.
If the LINK LED of an interface is off, the interface or the connecting cable may fail. Follow these steps to
troubleshoot the interface:
Check that the MPU or LPU where the interface resides works properly. For more information, see
Step1
failure" or "LPU
Check the cable connection of the interface. For how to correctly connect the cable to an Ethernet
Step2
interface with an RJ-45 connector or an optical interface, see the chapter "Connecting your switch to the
network."
Check whether the cable is broken. Use the cable to connect two interfaces of the same type that work
Step3
properly. If the LEDs of the two interfaces are on, the cable is normal. Otherwise, the cable fails. Use a
compliant cable to connect the interface.
If the interface uses a transceiver module, check that the interface type is compatible with the transceiver
Step4
module and that the transceiver module is compatible with the cable. For more information, see the
chapter "Appendix C Transceiver modules."
If the interface uses a transceiver module, make sure that the current transceiver module works properly
Step5
by replacing a normal transceiver module.
Use the display interface command to check whether the interface is UP. If the interface is not UP, use the
Step6
undo shutdown command to bring up the interface.
Check that the speed and duplex settings of the interfaces of a link are the same. Make sure that two
Step7
interfaces can work together.
If the failure still exists, contact the local agents or technical support engineers.

NOTE:
When an interface fails, if the switch has an idle interface of the same type, you can plug the cable into the
idle interface.
