Troubleshooting the SRPUs

The status LEDs on the SRPU show the status of a card in the corresponding slot. According to the slot
number of an SRPU, you can check the corresponding LEDs for the SRPU.
When the SRPU works properly, the RUN LED blinks, and the ALM LED is off. When the RUN LED is off,
the SRPU fails. Follow these steps to troubleshoot the SRPU:
Check that the power module works properly. For more information, see
1.
power supply
Check that the SRPU model is compatible with the chassis. For more information, see the chapter
2.
"Appendix B Pluggable module ordering guide."
Press the RESET button of the SRPU to reset the SRPU. After the SRPU is reset, check whether the
3.
corresponding RUN LED is on.
Check whether the SRPU is fully seated. You can unplug the SRPU, plug it again, and make sure
4.
that the SRPU is fully seated.
If the switch has empty SRPU slots, plug the SRPU into an empty SRPU slot, and check that the SRPU
5.
can work properly.
If the failure still exists, contact the local agents or technical support engineers.

Troubleshooting the LPUs

The status LEDs on the SRPU show the status of a card in the corresponding slot. According to the slot
number of an LPU, you can check the corresponding LEDs for the LPU.
When the LPU works properly, the RUN LED blinks, and the ALM LED is off. When the RUN LED is off, the
LPU fails. Follow these steps to troubleshoot the LPU:
Check that the SRPU works properly. For more information, see
1.
Check whether the console terminal prompts that the software version is incompatible with the LPU
2.
in the current slot. An LPU is compatible with a specific software version. If the software version is
incompatible with the LPU, upgrade the software to a compatible version.
Calculate the overall power consumption, and make sure that your power module can provide
3.
enough power. For more information, see the chapter "Appendix B Pluggable module ordering
guide."
Check whether the LPU is fully seated. You can unplug the LPU, plug it again, and press the ejector
4.
levers inward until the ejector levers touch the panel tightly.
If the switch has empty LPU slots, plug the LPU into an empty LPU slot, and check whether the LPU
5.
can work properly.
If the failure still exists, contact the local agents or technical support engineers.
