Application
Use this procedure to replace an NTRX42 card in a modular supervisory panel
(MSP) that supports a Remote Switching Center Multi-access (RSC-M)
cabinet.
Note: In this section, RCO2 in the examples refers to RSC-M. When
software outputs messages to the MAP terminal, software does not
differentiate between the two types of RCO2.

Action
A connector removal tool is available to facilitate removal of the AMP Faston
receptacles. This tool facilitates removal of these receptacles from the power
input and output connectors of the MSP modules. This tool comes in two
lengths: P0746192 152 mm (6 in) and P0747552 254 mm (10 in). You can
use the shorter tool when access to the rear of the MSP is limited. For example,
limited access can be MSP modules located behind the cabinet bulkhead.
This tool is approximately 2 mm (0.090 in) thick and 17 mm (0.65 in) wide,
with a jaw-like cutout at each end. The cutout profile conforms to the shape of
the Faston receptacle. You can use the shorter tip of each profile to position
the receptacle in the tool.
The first connection point of the tool serves as the pivot point. To engage the
longer profile tip with the action-arm of the power connector, rotate the tool
around the pivot point. The longer tip of the profile is the tip that has a hook
on the end. As the tool presses the action-arm of the connector, the receptacle
disengages from the connector tab. To remove the receptacle, pull the tool
away from the connector with the receptacle trapped in the jaw of the tool. To
disengage the tool from the receptacle, rotate the hook of the tool off the
action-arm of the receptacle.
The cutout shape is the same on each tool end, but the orientation of the profile
is off by 15 degrees. This difference enables the use of the tool at different
