iSCB Module PCBA Replacement (CS400-AC)

Prerequisites

● 002-00374C - iSCB module
● 22901-0225-00 - iSCB serial port cable assembly
● 22302-0313-01 - PCBA I/O network board
● 22309-00005-04 - PCBA CPU board

About this task

This procedure describes how to replace either of the two printed circuit board assemblies (PCBAs) in an iSCB
module. Reverse the process to replace the PCBAs.

Note:

 The two PCBAs are connected by a 28-pin connector as shown in the figure below. The CPU PCBA must

be removed first, before the I/O, network PCBA can be removed.
