Security
CHAPTER 1: BEFORE YOU START
The D20MX can be retrofitted into either a D20 3U single-node VME chassis or D20 3U non-
VME chassis. In a single-node VME chassis, this one processor module replaces the
previous D20 M, M++, ME, and MEII CPU cards.
Due to aging printed circuit board assembly and mechanical constraints, only certain
chassis from 2002 and onward can be used with a D20MX. This comprises the following
chassis:
• D20 VME chassis 500-0280 Release 08 or higher,
• D20 Non-VME chassis 500-0305 Release 18 or higher
A solid partition between the Main processor bay and accessory bay prevents access to
the harness from the fiber card to D20MX card (only applicable to the 526-3005LF fiber
card version).
The D20MX provides many new security improvements over its predecessors. To take
advantage of these improvements, refer to the WESMAINT II+ for the D20MX Configuration
Guide (B014-1NCG) for details on configuration of these security features of the D20MX.
D20MX applications
Table 2 lists the automation applications used on the D20MX. Notice that the application
versions are different in the SAN0001 and SAN0002 columns (for example, see application
ID B021N).
