may be out of order. In such a case and you should contact your Service
representative.
After Startup, All LEDs Remain On.
After startup, all LEDs should once, which indicates that the processor of the
module is in operation. If all LEDs are on, the module's system bus is not operating
normally or the CPLD is out of order.
The RUN LED Remains On.
When the module is in operation, the RUN LED should blink, rather than remain
on. If the RUN LED remains on, the module is powered on, but not operating
normally. It is possible that the module has been forced to reset. If there are other
LEDs that remain on simultaneously (for example, the ACT, SPEED, or DENY LEDs),
the encryption card may be faulty. If the encryption card is operating normally, the
faults may have occurred in the host.
The RUN LED Blinks Rapidly During Sartup
The rapid blinking of the RUN LED indicates that the module is initializing. During
this period, if the DENY LED blinks occasionally, there is a memory fault. In this
case, contact your Service representative to check the module. If, during
initialization, the SPEED LED is occasionally on, the booting of the module system
has failed. In this case, check the system configuration or contact your Service
representative.
The RUN LED Blinks Slowly After Startup
The slow blinking of the RUN LED indicates that the module is in offline. Check
whether the router host is properly configured and supports the encryption card.
The ACT LED Remains On.
When the ACT LED is flashing green, the module is upgrading the firmware. If the
ACT indictor remains on, the software upgrade has failed and the software should
be upgraded once again. If the ACT LED remains on after a second attempt to
upgrade, contact your Service representative.
The DENY LED Blinks during Normal Operation
When the DENY indictor blinks during normal operation, the module performance
or capacity is not adequate for encryption demands. This situation is not a
software or hardware failure. It is results from the technical specification limit of
the existing encryption module version. If necessary, contact your Service
representative to upgrade the encryption module with greater processing
capability.
