Testing and Diagnostics
Loopback tests, periodically sent from the processor modules, are
used to test the health of the I/O transceiver modules.
All detected failures produce an I/O module error indication on
the processor modules and a module fault indication on the I/O
transceiver module.
Front Panel Indicators
Figure 2 shows the physical features of the I/O transceiver
modules. The front panel of each module contains active and fault
status indicators.
Active and Fault Status Indicators
These green and red LEDs indicate the overall health of the
module. During normal operation the green ACTIVE indicator is
on. If a module fault occurs the red FAULT indicator turns on and
the green ACTIVE indicator turns off.
