Software Daughterboard

You must install the Software Daughterboard in its assigned connector on the
SSC card. The system and customer data is stored on the Software
Daughterboard. The Software Daughterboard is also used as a software
delivery card for new installations. Additional memory on the SSC card
temporarily stores and processes automated routines and user-programmed
commands. The SSC card also retains a copy of customer files, in the event
of data loss, in the Backup flash drive.
For Option 11C Mini fiber expansion, you must use an NTTK13 Software
Daughterboard with Release 24.24 or later software. The NTTK13 provides
48 Mb of memory.

Security Device

The NTDK20 SSC card has a socket where you install the Security Device.
A Security Device is shipped with each new system.
Note: You can use the Security Device that was on the Mini System
Controller (MSC) card.
