Server 95 - Advanced Diagnostics hang

Applicable to: AP-S, Canada, LA, United States

Source: RETAIN tip H124054

Abstract: Advanced Diagnostics hang

SYMPTOM:
The system hangs while loading diagnostics after the "Control- A" command at the Main Menu, followed by the "System Checkout" selection. All models of the 8595 and 9595 are affected.

PROBLEM ISOLATION AIDS:
If the parallel port is set to "Disabled" and the model 90/95 Diagnostic Diskette version is below version 2.20, hangs may occur.

1. To determine if the parallel port is disabled:

Enter the System Partition, then from the Main Menu, choose "Set configuration." Next, select "View configuration" to determine the setting of the "System board parallel port B" for 9595 systems (which has two parallel ports), or the "System board parallel port" for 8595 systems. Make a note of the customer's parallel port configuration.

2. To determine the Diagnostic Diskette version being used:

Return to the system partition "Main Menu" and select "Display Revision Levels" to determine the Diagnostic diskette version. (This screen may be found under "Other Utilities" at the Main Menu on some systems.)

The following screen will be seen:

Revision level	X.
Reference Diskette version	X.XX
Diagnostic Diskette version	?.?? (Below 2.20 affected)
Diagnostic Version	X.XX
Config. util. version	X.XX

(The information shown as "X" does not matter.)

FIX:
This condition will be corrected in the next IML (Reference and Diagnostic Diskette) update.

Workaround:
Before using the following procedure, save the customer's configuration settings with "Save Configuration". This will allow restoring the original configuration by use of the "Restore Configuration" option.

Before running the Advanced Diagnostics, change the configuration of parallel port B to the default settings (use auto-config.). When testing is completed, reconfigure to the customers original settings by setting it manually or using "Restore Configuration."
