5.
If the switch has empty SRPU slots, plug the SRPU into an empty SRPU slot, and verify that the SRPU
can operate correctly.
6.
If the failure persists, 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 examine the corresponding LEDs for the LPU.
When the LPU is operating correctly, the RUN LED flashes, and the ALM LED is off. When the RUN LED
is off, the LPU fails.
To troubleshoot the LPU:
1.
Verify that the SRPU is operating correctly. For more information, see "
."
2.
Verify that the console terminal prompts that the software version is compatible with the LPU 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.
3.
Calculate the overall power consumption, and make sure your power module can provide enough
power. For more information, see "Appendix B Pluggable module ordering guide."
4.
Verify that the LPU is fully seated. You can unplug the LPU, plug it again, and press the ejector
levers inward until the ejector levers touch the panel tightly.
5.
If the switch has empty LPU slots, plug the LPU into an empty LPU slot, and verify that the LPU is
operating correctly.
6.
If the failure persists, contact the local agents or technical support engineers.
Troubleshooting interfaces
The interfaces provided by SRPUs and LPUs all have corresponding LEDs. When an interface connected
to the network is operating correctly, the corresponding LED is on.
NOTE:
A management Ethernet interface, SFP+ interface, or XFP interface each has two LEDs, LINK and ACT. The
LED mentioned in this section for such an interface refers to the LINK LED. Each interface of any other type
has only one LED.
If the LED of an interface connected to the network is off, the interface or the connecting cable might fail.
To troubleshoot the interface:
1.
Verify that the SRPU or LPU where the interface resides is operating correctly. For more information,
see "
."
2.
Verify the cable connection of the interface. For how to correctly connect the cable to an Ethernet
interface with an RJ-45 connector or an optical interface, see "
."
3.
Verify that the cable is not broken. Use the cable to connect two interfaces of the same type that are
operating correctly. 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. For more information about the
compliant cables, see "
