1. Verify that the Power LED is on.
2. The 20 Port LEDs are initially red. These LEDs indicate that a loss of signal has
occurred.
3. Press the Reset button on the front panel of the Analyzer. All 20 Port LEDs
change to green.
If any port has a signal level below the threshold, either continuously or
momentarily, the corresponding Port LED changes to red. Refer to
Troubleshooting Using the Output Fault
on diagnosing faults using the Analyzer.
When testing is completed, remove the Analyzer from the slot. Return the Analyzer
to the unpowered storage slot. Do not leave the Analyzer installed in an active slot.

Troubleshooting Using the Output Fault Analyzer

Non-Redundant Modules
If the Analyzer does not indicate a fault (even though a fault is indicated elsewhere),
an improper or incorrect signal may be present. The Output module could be faulty.
If the Analyzer indicates a fault, inspect the wiring on the indicated port.
Redundant Modules
If the Analyzer does not indicate a fault, an improper or incorrect signal may be
present. If both Output modules indicate a fault before installing the Analyzer, install
the Analyzer and inspect the wiring on the indicated port. If only one Output module
indicates a fault before installing the Analyzer, then the Output module with the fault
could be defective.
