	MIM-2VE1 Module 117
Table 77 Description of the LEDs on the MIM-HNDE panel
LED	Indication
STATUS	ON (green): The MIM-HNDE module is
	powered on properly.
	OFF: There is no power supply, damaged
	power supply, or sever hardware failure.
ACTIVE	OFF after flashing yellow for two seconds:
	Initialized the MIM-HNDE module.

Blinking continuously: The MIM-HNDE module operates normally and there is data transmission with the host.

OFF: MIM-HNDE module runs normally and no data transmission exists with the host.

Troubleshooting

1Symptom 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.

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.

2Symptom 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.

3Symptom 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.
