Diagnosing a problem
Before you contact Unisys or an approved warranty service provider, follow these
procedures in the order in which they are presented to diagnose a problem with your
server:
1. Determine what has changed.
Determine whether any of the following items were added, removed, replaced, or
updated before the problem occurred:
• Hardware components
• Device drivers and firmware
• System software
• Server firmware
• System input power or network connections
If possible, return the server to the condition it was in before the problem occurred.
2. View the light path diagnostics LEDs and event logs.
