2.
Check whether the console terminal prompts that the software version is incompatible with the card
in the current slot. If the software version is incompatible with the card, upgrade the software to a
compatible version.
3.
Calculate the overall power consumption, and make sure that your power supplies can provide
enough power. For more information, see the chapter “Appendix B FRUs and compatibility
matrixes.”
4.
Check whether the card is fully seated. You can unplug the card, plug it again, and press the
ejector levers inward until the ejector levers touch the panel tightly.
5.
If the switch has empty card slots, plug the card into an empty card slot, and check whether the
card can work properly.
6.
If the failure still exists, contact the local agents or technical support engineers.
Interface failure
The interfaces provided by MPUs and LPUs all have corresponding LEDs. When an interface connected
to the network works properly, the corresponding LED is on.
NOTE:
A management Ethernet 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.
To troubleshoot the interface:
1.
Check that the MPU or LPU where the interface resides works properly. For more information, see
“
MPU failure
” or “
LPU and switching fabric module failure
.”
2.
Check 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 the chapter “Connecting your switch
to the network.”
3.
Check whether the cable is broken. Use the cable to connect two interfaces of the same type that
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.”
4.
If the interface uses a transceiver, check that the interface type is compatible with the transceiver
and that the transceiver is compatible with the cable. For more information, see the chapter
“Appendix B FRUs and compatibility matrixes.”
5.
If the interface uses a transceiver, make sure that the current transceiver works properly by
replacing a normal transceiver.
6.
If the interface is a combo interface (which contains a fiber and a copper port), make sure that the
port used for connection is activated for the combo interface. Then, use the
combo enable
{
copper
|
fiber
} command to activate the port, and check the LED.
