Troubleshooting Cf Cards - H3C S7500E Series Installation Manual

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 may fail.
Follow these steps to troubleshoot the interface:
Check that the SRPU or LPU where the interface resides works properly. For more information, see

interface with an RJ-45 connector or an optical interface, see the chapter "Connecting your switch
to the network."
Check whether the cable is broken. Use the cable to connect two interfaces of the same type that
3.
work properly. 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 the chapter "Appendix D Cables."
If the interface uses a transceiver, check that the interface type is compatible with the transceiver
4.
and that the transceiver is compatible with the cable. For more information, see the chapter
"Appendix B Pluggable module ordering guide."
If the interface uses a transceiver, make sure that the current transceiver works properly by
5.
replacing a normal transceiver.
If the interface is a combo port (which contains an optical interface and an electrical interface),
6.
make sure that the interface used for connection is activated for the combo port. Then, use the undo
shutdown command to activate the port, and check the LED. For more information, see the chapter
"Hardware management and maintenance."
NOTE:
A combo port comprises an SFP interface and an RJ-45 Ethernet interface. Only one of them can be
•
activated at a time.
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 switch has an idle interface of the same type, you can plug the cable into
•
the idle interface.
Check that the speed and duplex settings of the interfaces of a link are the same. Make sure that
7.
two interfaces can work together.
If the failure still exists, contact the local agents or technical support engineers.

Troubleshooting CF cards

The SRPU provides a CFS LED. When the CF card works properly, the CFS LED is on.
If the CFS LED is off, the CFD card fails. Follow these steps to troubleshoot the CF card:
Check that the SRPU works properly. For more information, see
1.
If the CF card fails because you execute the umount command, you can execute the <Sysname>
2.
mount cfa0: command in user view to re-mount the CF card.
Check whether the CF card is fully seated.
