For safety reasons and to prevent accidental damage to a user supplied external bulk DC
Power Supply, it is recommended that pluggable Terminal Block connector TB1 be discon-
nected from the SCM until the entire unit has been wired, and hardware configured.
Sections 2.3.9.1 & 2.3.9.2 provide details on DC Power Connector TB1 wiring.

2.3.3 CPU Module & ECOM Module Configuration
To configure the CPU Module, Jumpers must be set (see Figure 2-9), DIP-Switches must be
set (see Section 2.3.3.1) and Communication Ports must be wired (see Sections 2.3.3.2
through 2.3.3.3). The CPU Module resides in Base Chassis Backplane Slot #2 (see Figure 2-
2). Backplane Slot #2 provides 44-pin female interface connector P2 on the bottom and 36-
pin female interface connector P3 on the top.
2.3.3.1 CPU Module Switch Configuration
ControlWave EFM CPU Module DIP-Switches must be set for the desired performance
options. Tables 2-2, 2-3 and 2-6 provide an overview of switch settings.
SW2-1 set OFF will disable the system from entering a watchdog state when a crash or
system hangup occurs. Setting SW2-1 OFF prevents the system from automatically
restarting.
SW2-2 set OFF prevents changing the Soft Switches, other configurations and FLASH files,
i.e., these items are locked. To change Soft Switch, configuration and FLASH files SW2-2
must be set to the ON position (see Section 2.4.4).
