ESCON 2

- Troubleshooting Guidelines
The ESCON Adapter includes a Light Emitting Diode (LED) Display on the back
edge of the adapter. This LED Display is located on the top half of the ESCON card
and can be used to help isolate whether a problem is hardware or software related.
Depending on the state of the card, the scrolling message on the LED Display will
vary. When the 2074’s power is turned on, the LED Display should always be
illuminated. The following table illustrates the meaning of the scrolling LED Display
messages.

As soon as the system is powered on, under normal operation, the ESCON adapter
executes its 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:
Steps
1. If the LED Display is off, power down your 2074, remove the adapter, and
re-install it. Make sure the adapter is properly seated in the slot. Power the
2074 back on. If the LED Display remains unlit, replace the ESCON adapter. If
you have already replaced the ESCON adapter, contact the next level of
service.
2. When your 2074 is first powered on, the LED Display will scroll through the
Power on Self Test (POST) messages. Once this completes, the LED Display
will scroll through the firmware level message and the
″
Adapter closed
″
message. This sequence will persist until the ESCON adapter device driver is
loaded during OS/2 boot-up. If the POST sequence on the LED Display gets
stuck at one point for at least 5 minutes, then power down the 2074 and
reinstall the adapter. If the condition repeats itself, replace the ESCON adapter.
If you have already replaced the ESCON adapter, contact the next level of
service.
