Defect security switches. If all compartments and devices are installed and security error
will not authorize, replace DCI security switches.
Malfunction Signal Backplane. If switch replacement is not the solution, then replace
Signal Backplane. See "Replacement of the signal back plane", page 231.
The Security Log Error indicates that there is no more room to write log entries in the link
decryptor log file.
When this error is active, the DCI compliant Server needs to extract the log data (via
ASM/TLS session) from the link decryptor Security Log. Reads of the security log by any
other entity/means will not impact this error. This error will remain active until the Server
reads enough log entries to create room for 512 log entries. This can take some time.
Playback will be prohibited (black image) as long as this error is active.
The battery of the link-decryptor is low. Leave the projector on for some time to recharge
the battery.
The security log warning indicates that there are less than 512 log entry locations
available in the link decryptor log before the log is full. The attached server needs to
read the log which will clear the log of the projector.
When this warning is active, the DCI compliant server needs to extract the log data (via
ASM/TLS session) from the link decryptor Security Log. This can take some time. Reads
of the security log by any other entity/means will not impact this warning.
Solution
Replace link decryptor. See "Replacement of the Link Decryptor", page 243.
