Check that the power supply of therouter is correctly connected.2. Check that the power is being supplied.3. Contact your sales agent for help: thepower supply of the module may havebeen damaged or anomalies haveoccurred to the CPLD.ACTIVE LED remains off atdevice startup.The encryption processorfailed to initialize theconfigurations possiblydue to a system busproblem.1. Check that the module is securelyconnected to the host.2. Contact your sales agent for help: thehost or the module may be problematic.
