Switching fabric module failure
The switching fabric module provides SLOT10 and SLOT 11 LEDs to indicate the operating status of the
corresponding switching fabric modules. If the LED is not flashing green, the switching fabric module is
faulty.
To troubleshoot the switching fabric module:
1. Verify that the power system is operating correctly. For more information, see " Power module
failure ."
2. Verify that the switching fabric module is correctly installed. Remove the switching fabric module
and reinstall it to make sure the module is correctly installed. For more information, see "
Installing
switching fabric modules for the S9810 switch ."
Before you remove the switching fabric module, remove the fan tray immediately above it.
3. Press the RESET button on the switching fabric module.
4. If the problem persists, contract H3C Support.
LPU failure
When the LPU is operating correctly, the SLOT LED is flashing green. When the SLOT LED is not flashing
green, the LPU is faulty.
To troubleshoot the LPU:
1. Verify that the switch software version is compatible with the LPU. If it is not, upgrade the software
to a compatible version.
2. Calculate the total power consumption, and make sure the power modules can provide enough
power. For more information, see "
Appendix A Chassis views and technical specifications ."
3. Verify that the LPU is fully seated by removing and reinstalling the LPU. For more information about
installing an LPU, see "
Installing an LPU ."
4. If the switch has empty card slots, install the card into another slot. If the card can operate correctly,
the previous slot is faulty.
5. If the problem persists, contract H3C Support.
Interface failure
The switch provides an LED for each interface on LPUs. When an interface connected to the network is
operating correctly, the LED is steady on.
