Switching Fabric Module Failure; Technical Support - H3C CR16000-M Installation Manual

information about how to correctly connect a cable to an optical interface, see "Installing a
transceiver module and connecting optical fibers."
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. For more information, see
H3C CR16000-M Routers Hardware Information and Specifications.
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.
6. If the issue persists, contact H3C Support.
NOTE:
• If an interface is brought down by the
command to bring up the interface.
• After an interface fails, you can use an idle interface of the same type (if any) on the router to
replace it.

Switching fabric module failure

A switching fabric module uses a RUN LED and ALM LED to indicate its operating status. When the
switching fabric module is operating correctly, the RUN LED flashes at 0.5 Hz and the ALM LED is off
Symptom
The RUN LED on a switching fabric 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 switching fabric module is compatible with the system software. Upgrade the
system software if it does not support the switching fabric module.
3. Calculate the total power consumption, and make sure your power supplies can provide
enough power. For more information, see H3C CR16000-M Routers Hardware Information and
Specifications.
4. Ensure that the switching fabric module is installed securely. Remove the switching fabric
module, reinsert it into the slot, and then rotate inward the ejector levels until the ejector levers
touch the front panel of the switching fabric module tightly.
5. If the router has an empty switching fabric module slot, install the module in the empty switching
fabric module slot. If the module operates correctly, the previous slot is faulty.
6. If the issue persists, contract H3C Support.
