3.2 MP20S MODULES
This section describes the procedures for setting switches, installing optional daughter
boards, and installing the boards in a slot.
The OfficeServ 7200-S MP20S (Main Control Processor) controls the system operation. The
MP20S is required for all configurations and goes in slot 0 of the cabinet.
3.2.1 Setting Switches on the MP20S
The MP20S processor card does not have a memory backup switch because it uses volatile
NAND flash memory to store the database.
See Section 9.2, Database Management on the
MP20S and use of the RESET button
. There is a set of dip switches designated as S3 (see Figure
3.3b, MP20S Switch Settings) used to customize the user requirements and system
configuration at start up. The description of each setting is described below.
On the MP20S set the switches for the required configuration. The description for the settings
is described below.
