Setting the Memory Switches
The memory configuration is set by Switches 1 and 2 (leftmost) of the
DIP switch bank shown in Figure 22. The four memory switch settings
(2, 4, 6, 8, and 10 MB of DRAM) are shown in Table 18. Figure 22
shows a 4 MB memory configuration (Switch 1=down, Switch 2=up).

If the memory configuration is different from the actual SIMMs installed, an LED error may be indicated during
the power on self tests. See Troubleshooting in this document.
* Memory switches are not used in the NCM350-8. The NCM350-8 comes with 8 MB memory.
NCSETUP for Windows Operating System (WNCSETUP)
NCSETUP for Windows operating system (WNCSETUP) is a
software utility that sets up and modifies the non-volatile RAM
(NOVRAM) configuration. It replaces the DOS version of NCSETUP.
WNCSETUP provides several status and diagnostic functions in
addition to storing the system paths by which a restarted NCM can call
data and applications from archive files.
WNCSETUP is also the utility that establishes to the system what type
of NCM (what program set - standard, security, S2 Migration) you are
commissioning.
You must have the Metasys system running on the OWS in order to
use WNCSETUP. For complete information on WNCSETUP, see the
NCSETUP for Windows Technical Bulletin (LIT-6360251d).
