3.13.5 Troubleshooting

1)Symptom 1: The STATUS LED stays off after turning on the router.

Troubleshooting: The STATUS LED should stay solid on after powered on. The OFF status indicates that the Router NDEC2 Encryption Accelerator MIM or some hardware is not powered on properly. Check the connection of the power supply.

If the device is powered on, the failure may due to the damaged power supply of the module, or abnormal operation of CPLD (Complex Programmable Logic Device). In these circumstances, contact our agents for support.

2)Symptom 2: The ACTIVE LED stays off when powering on the router.

Troubleshooting: When powering up the device, the ACTIVE LED should flashing for two seconds before turning off, which indicates the encryption processor of the Router NDEC2 Encryption Accelerator MIM has been configured and is ready for work. If the ACTIVE LED stays on when powering up the device, this means the initialization of the processor fails and the system bus does not work normally. Check the connection between the Router NDEC2 Encryption Accelerator MIM and the host. If the connection is good, the abnormal status may due to the host or the Router NDEC2 Encryption Accelerator MIM, contact our agents for support.

3)Symptom 3: The ACTIVE LED stays on or off when the Router NDEC2 Encryption Accelerator MIM is running.

Troubleshooting: The ACTIVE LED should be blinking when the Router NDEC2 Encryption Accelerator MIM runs the encryption service. The solid on or off indicates the system bus works abnormally. Check the connection between the Router NDEC2 Encryption Accelerator MIM and host. If the connection is good, the abnormal status
