If you cannot locate and correct the problem using the information in this section,
refer to the " Solving problems" section on the IBM Netfinity Documentation CD and the
"Support for Netfinity Servers" flowchart in the front of this booklet.
POST beep code descriptions
Post be ep code descript ions POST emits one beep to signal successful completion. If POST detects a problem
during startup, other beep codes might occur. You can use the following beep code
descriptions to help identify and resolve problems that are detected during startup.
Note: See the "Solving problems" section of the User’s Reference on the IBM Netfinity
Documentation CD for more information about the POST beep codes.
