Card Types
The types of memory cards are described below. The card type is identified
by a preprinted, color-coded label.
Upgrade Card. This card is used for MERLIN LEGEND
Communication System software upgrades. The upgrade can be
performed by the system manager using the memory card and the
Maintenance option on the SPM Main Menu. See Maintenance and
Troubleshooting for information about this feature.
This card is identified by an orange label with black lettering.
Translation Card. The backup and restore procedures previously
available to system managers through SPM (using the PC and floppy
disks) can now be performed using the memory card and the new
Backup/Restore option on the System menu. A new automatic backup
feature permits you to set the system to perform automatic backups to
the memory card on a daily or weekly basis. See "Backup" and
"Restore" for more information.
This card is identified by a white label with black lettering.
Forced Installation. For use by qualified service technicians only, this
card is used when the system software has been corrupted and a re-
installation must be done at the customer site. The use of the card for
forced installation is reserved for emergency situations in which the
system software on the processor module has been damaged.
This card is identified by an orange label with black lettering. In
addition, black stripes are present on the card to distinguish it from an
upgrade card.
