TECHNICAL MANUAL
3.2 MP40 AND LP40 MODULES
This section describes the procedures for setting switches, installing optional daughter
boards, installing the boards into slots, and how to connect between the MP40 and
LP40 boards.
The OfficeServ 7400 MP40 (Main Control Processor) controls the system operation.
The MP40 is required for all configurations and goes in slot 3 of the main cabinet. The
LP40 goes in slot 0 of the MAIN cabinet and each OS7400 expansion cabinet. If the
expansion cabinet happens to be an OS7200 cabinet, then slot 0 must have an
OS7200 LCP card NOT the LP40 card.
The LP40 is a secondary processor that communicates with the MP40 and manages
the boards in the expansion cabinets.
3.2.1 Setting Switches
The MP40 board includes switches used for optimizing the board to the user
requirements and system configuration.
On the MP40, set the switches for the required configuration. The description for the
settings is described below.
• (S1): SRAM Memory Backup Switch: When set to ON, it allows the SRAM to store
information such as Call Logs, Alarms, UCD call stats, program logs and traffic
reports. SRAM is backed by the Super Capacitor on the MP40. If the switch is ON,
data can last up to 12 hours without main system power. This switch is also used to
default the system.
