PROJECT 25 ERROR AND WARNING MESSAGES
L-1
ERRORS
Project 25 errors fall into two categories:
EMC/Encryption Key Errors and Project
25 Errors. Error messages are defined
as: "Messages displayed to alert the user
to failures which affect system or test
functionality." A summary of
EMC/Encryption Key and PROJ 25
Errors follows.
L-1.1 EMC/Encryption Error
Messages
The following errors occur when there
has been an error or failure that prevents
encryption decode or encode from
operating correctly. The probable cause
for the error, along with a recommended
solution is presented.
(qwdId: quick, what do I do?)
Hardware Failure- Perform Encrypt
Reset
This message indicates that the
Hardware Encryption Modules have
failed. The system has either been
unable to communicate with one or
both of the modules or the module
has indicated that is has experienced
a startup error.
qwdId:
Perform encrypt reset from the
Special Function window. If the
problem persists, contact the Service
Representative.
Appendix L
Warning-External Key Lost
This message is displayed when a
Powerup Configuration Failure has
occurred. This is most likely due to
a Password Validation Failure. In
this case, all previously stored keys
and passwords have been erased as
part of the hardware recovery
process.
qwdId:
If an External Key is required, it
must be reloaded using a DX type
KVL or any KVL 3000 with the
ASN option.
Key Invalid-Verify Key Loaded
The user has attempted to use an
External Key which is not available
for the selected algorithm or
encryption type.
qwdId:
This error can be cleared in one of
two ways. You can either test using
the TEST KEY or you can load an
External Key using a DX type key
loader, or any KVL 3000 with the
ASN option. To continue testing
using the TEST KEY, select the
correct algorithm from the SET UP
menu. Select the TEST KEY
softkey. To test using the External
Key in the SET UP menu, select the
correct algorithm and then select the
load ext key softkey. Connect a DX
key loader, or any KVL 3000 with
the ASN option, which matches the
selected algorithm to the R625.
