Troubleshooting 47

Chapter 6. T

ROUBLESHOOTING

If your PCI ESCON Adapter fails to initiate successfully this chapter will provide you
with some general troubleshooting guidelines to help you identify and fix your
problem.

If after you have been through this troubleshooting chapter you are still unable to
make your adapter work properly please refer to the section titled “Help and Service
Information” on page 53 for information on obtaining help.

Hardware

The ESCON adapter includes two Light Emitting Diodes (LEDs) on the back edge of
the adapter. These LEDs are located just below the ESCON connector and can be
used to help isolate whether a problem is hardware or software related.

Each LED will illuminate in one of three colors. The top LED illuminates Red,
Yellow, or Green. The bottom LED illuminates Red, Orange, or Green. When the
server’s power is turned on both LEDs should always be illuminated. Table 6-1
summarizes the use of each LED.

Table 6-1. Status LED Summary

As soon as the system is powered on, under normal operation the ESCON adapter
executes it’s own Power On Self Test (POST) and then loads the emulation firmware.
Follow the steps below to determine if the adapter has powered on successfully and is
operational.
