INTRODUCTION
This section explains what happens to the IMMFP12
Multi-Function Processor (MFP) Module during start-up, the
LED indicators and what they mean, how to stop or reset the
module, and the three modes of operation.
STARTUP
When power is applied to the MFP module, the module does an
internal hardware check, checks its configuration and builds
the necessary databases.
During start-up of primary modules, the front panel LEDs will
go through the following sequence:
1. All front panel LEDs will illuminate red.
2. The status LED will change from red to green.
3. LEDs 1 through 6 will turn off.
During start-up of secondary modules, the front panel LEDs
will go through the following sequence:
1. All front panel LEDs will illuminate red.
2. The status LED will change from red to green.
3. All LEDs will turn off.
4. LED 7 will illuminate red and then turn off.
5. LED 8 will illuminate red.
If the appropriate LEDs do not illuminate, refer to
for
more details.
LED INDICATORS
There are nine LEDs visible through the faceplate window.
Eight CPU LEDs reflect the on-board microprocessor status.
The status LED, located above the CPU LEDs, reflects the over-
all module status. Refer to Figure
for the exact location of
the LEDs.
