Troubleshooting the HNDE Module
1) Symptom 1: The STATUS LED stays off after turning on the V100-E.
Solution: The STATUS LED should stay solid on after powered on. The OFF status indicates that the
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.
2) Symptom 2: The ACTIVE LED stays off when powering on the V100-E.
Solution: When powering up the device, the ACTIVE LED should flashing for two seconds before
turning off, which indicates the encryption processor of the 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
HNDE module and the host. If the connection is good, the abnormal status may due to the host or the
HNDE module, contact our agents for support.
3) Symptom 3: The ACTIVE LED stays on or off when the HNDE module is running.
Solution: The ACTIVE LED should be blinking when the HNDE module runs the encryption service. The
solid on or off indicates the system bus works abnormally. Check the connection between the HNDE
module and host. If the connection is good, the abnormal status may due to the host or the HNDE
module, contact our agents for support.
