7-2
8) Connect the two ends of the optical fiber to the TX and RX ends of the same optical transceiver to
check connectivity of the optical interfaces. If the optical interfaces still cannot connect to the
network, connect the optical fiber in the same way to the optical interfaces that work normally. If the
optical interfaces still cannot connect to the network, the optical transceiver is faulty. Use the other
optical transceiver or replace it with another one, and then perform the same test.
9) The length of the optical fiber does not exceed the distance supported by the optical transceiver.
10) If the problem still exists, contact the service engineer.
10-GE Interface Card Problem of the WX3024
Symptom
After you insert the 10-GE interface card to the WX3024, the card cannot work.
Solution
Check that:
1) The AC starts up completely and you can see the user prompt.
2) Enter the oap connect slot 0 command in user view on the WX3024.
3) You have properly installed the 10-GE interface card to the MOD slot of the WX3024, and fastened
the captive screws.
4) The installation prompt is printed at the terminal upon insertion of the interface card. If not, insert
the card to another MOD slot. If the problem still exists, the 10-GE interface card is faulty.
5) If the MOD LED of the slot installed with the 10-GE interface card on the front panel blinks yellow,
the interface card is faulty. Replace it with another one.
6) The 10-GE interface card is supported by the WX3024. For optical transceivers supported by the
WX3024, see Appendix A Specifications of Optional Interface Modules in the installation manual
supplied with the WX3024.
7) The optical fiber is correct and works well. Otherwise, replace it with another one.
8) Insert an optical transceiver to the 10-GE interface card. Then connect the TX and RX ends of the
optical transceiver with an optical fiber, and check the MOD LED on the front panel. If the LED is
not steady green, use another optical transceiver to do the same test. If the optical transceiver
works normally on other interface cards, the 10-GE interface card is faulty.
9) Contact the service engineer after the above steps.
Over-Temperature Alarm
Symptom
The AC prompts an over-temperature alarm, and the status LED or alarm LED indicates an alarm. For
description of the LED statuses, see the LED description in the installation guide supplied with the AC.
Solution
Check that:
1) The AC starts up completely.
2) The operating temperature of the AC falls in the range 0°C to 45°C (32°F to 113°F).
3) All fans run normally.
4) Execute the display environment [ cpu ] command to check the temperatures of relevant
components of the AC.
