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 MIM-HNDE module or some hardware is not powered on
properly. Check the connection of the power supply.
status indicates that the MIM-HNDE module 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.

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 MIM-HNDE module 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 MIM-HNDE module and the host. If the connection is good, the
abnormal status may due to the host or the MIM-HNDE module, contact our
agents for support.

3 Symptom 3: The ACTIVE LED stays on or off when the MIM-HNDE module is
running.
Troubleshooting: The ACTIVE LED should be blinking when the MIM-HNDE
module runs the encryption service. The solid on or off indicates the system bus
works abnormally. Check the connection between the MIM-HNDE module and
host. If the connection is good, the abnormal status may due to the host or the
MIM-HNDE module, contact our agents for support.
