SECTION 5 - TROUBLESHOOTING
INTRODUCTION
This section contains IMMFP03 Multi-Function Processor
(MFP) Module troubleshooting information. Included is infor-
mation on module error codes, troubleshooting flowcharts,
diagnostic routines available, and the module status sum-
mary. Refer to Table
for MFP error codes, their meanings
and appropriate corrective action. Table
shows all other
LED states. The flowcharts in Figures
and
provide a
quick look at hardware associated problems that may occur
during module installation and start-up.
Diagnostic tests help determine if there is a problem with
module components or circuitry. They are useful for testing
the module when the system is down or there is some other
means of controlling the process. For example, use the
backup module (if redundant modules are installed) to con-
trol the process while testing the primary module. The mod-
ule status summary is a 16-byte module status record that
provides summary flags for error conditions, module type,
and firmware revision level.
