INTRODUCTION
This section contains faceplate LED error codes, edge connec-
tor pinouts, cable connector pinouts, and explains the use of
diagnostic tests.
LED DISPLAY
The IMCPM02 module has one two-color status LED on the
faceplate to indicate the execute or failed status of the
IMCPM02 module (see Figure
). It has eight red status LEDs
on the faceplate for diagnostic purposes and as an activity indi-
cator. The LEDs are arranged vertically and numbered from
one through eight, top to bottom. Refer to Table
.
In normal operation, the LEDs indicate activity through either
the CTT or EWS port. When the IMCPM02 module is in a failed
state, LEDs 1 through 8 display a code indicating the error
condition (refer to
