System Security
System security is maintained by comparing identification codes contained
in the Security Block device attached to the VisionMaster PC (see System
Startup) with the codes contained in the system configuration file.
The following rules govern system security:
In order for the system to operate effectively, a Security Block
device must be properly programmed by Sperry Marine and
attached to the PC. On a two-node system both nodes have a
Security Block attached.
If the Security Block becomes damaged or detached while the
system is running, an Authorization Failure alarm is given. The
system will continue to operate but will revert to a degraded state
after a period of 7 days. If the Security Block is damaged the
operator should contact their supplier Sperry Marine to apply for a
replacement.
If on startup an invalid system identification code is found in the
configuration file, the system will shut down. No grace period is
provided.
While the Security Block is broken or detached, installation of
charts is prohibited. This is true even if the user has obtained a
temporary security password.
