NDEC Modules of H3C Series Routers

I.          Preface

Network data encryption card module is primarily used for router data flow encryption. It implements IPSec with encryption feature, where encryption service is enabled by the encryption card.

II.        Introduction to Modules

NDEC is the short of Network Data Encryption Card. NDEC supports IPSec protocol and provides high performance and high reliable encryption feature for routers through the encryption process of hardware expedited IP packets.

When inserting NDEC module, router main process unit fulfills the routing and forwarding of IP packets, and enables VPN with encryption feature. The encryption is performed by the encryption card.

VI.     Troubleshooting Modules

Symptom 1: All indicators extinguished constantly after started.

Solution: all indicators should fast light one time when starting. If not, this means the module or some hardware on the module did not power on. Please examine whether the system power is connected correctly.

If system power works, the fuse may burn out or CPLD (Complex Programmable Logic Device) may wrong. Please contact Huawei-3Com agent.

Symptom 2: All indicators light constantly after started.

Solution: all indicators should fast light one time when starting, and then extinguished immediately. This means the module processor works. If all indicators is lighting, it means the system bus did not work or CPLD is exceptional.

Symptom 3: RUN indicator lights constantly.

Solution: RUN should flash, not light constantly when the module works. If so, this means the module powers on but did not work. The module may be forced to reset. If there is other 1-2 indicators lighting (If ACT lights, or SPEED lights or DENY lights)，this indicates the encryption card failed. Or the host failed. RUN becomes lighting after flashed several times, this means initiation failed.

Symptom 4：RUN is fast flashing when starting.

Solution: RUN fast flashing means the module initiates. And it is fast flashing until the initiation is completed. At this point if DENY flashes occasionally, this means memory failure, please contact Huawei-3COM agent. If SPEED lights occasionally during this period, this means system boot failure, please examine system configuration or contact Huawei-3Com agent.

Symptom 5：RUN is slow flashing after started.

Solution: RUN slow flashing means the module gets into an offline state. You should examine whether the router configuration is right and supports encryption card.

Symptom 6：ACT lights constantly.

Solution: ACT flashing means the module upgrades firmware. ACT lighting means software upgrade failed, you should upgrade software again. If the problem still exists, please contact Huawei-3COM agent.

Symptom 7：DENY flashes when operation.

Solution: DENY flashing means the module performance or the capacity cannot meet the encryption requirement at the moment. This is due to the technology specification limitation of the current version of encryption module, not a hardware/software fault. Please contact Huawei-3Com agent as required, upgrading to encryption module with higher processing capability.
