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
ON (green): The Router NDEC2 Encryption Accelerator MIM is powered on
properly.
OFF: There is no power supply, damaged power supply, or sever hardware
failure.
OFF after flashing yellow for two seconds: Initialized the Router NDEC2
Encryption Accelerator MIM.
Blinking continuously: The Router NDEC2 Encryption Accelerator MIM
operates normally and there is data transmission with the host.
OFF: Router NDEC2 Encryption Accelerator MIM runs normally and no data
transmission exists with the host.
