3.
Calculate the total power consumption, and make sure your power modules can provide
enough power. For more information, see
H3C S12500G-EF Switch Series Hardware
Information and Specifications
.
4.
Remove and reinstall the fabric module to make sure the module is installed securely. You also
need to verify that the ejector levers are locked securely in place. For more information, see
"Installing FRUs."
5.
If the device has empty fabric module slots, install the module in an empty fabric module slot. If
the module operates correctly, the previous slot is faulty.
6.
If the issue persists, contract H3C Support.
Interface failure
Symptom
The LED for an interface is off.
Solution
To resolve the issue:
1.
Make sure the MPU or service 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 your device to the network."
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. Otherwise, the cable is faulty. Use a compliant cable to connect the interface. For
more information, see
H3C S12500G-EF Switch Series Hardware Information and
Specifications
.
4.
If the interface uses a transceiver module, perform the following tasks:
a.
Make sure the interface type is compatible with the transceiver and that the transceiver is
compatible with the cable. For more information, see
H3C S12500G-EF Switch Series
Hardware Information and Specifications
.
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
shutdown
command, use the
undo shutdown
command to bring up the interface.
•
After an interface fails, if the device has an idle interface of the same type, you can connect
the cable to the idle interface.
Technical support
Before contacting H3C Support, prepare the following information:
•
Arrival time of the device.
•
Serial number of the chassis (on the label at the right of the rear panel).
•
Software version, which you can view by using the
display version
command.
•
Maintenance agreement or warranty card.
•
Brief issue description.
