The power-on self-test beep codes indicate the detection of a problem.
– One beep indicates successful completion of POST.
– More than one beep indicates that POST detected a problem. Error messages
also appear during startup if POST detects a hardware-configuration problem.
See "POST beep code descriptions" on page 56 and the blade server Hardware
Maintenance Manual and Troubleshooting Guide on the IBM Documentation CD
that comes with the BladeCenter unit for more information.
The table in "ServerGuide problems" on page 58 lists problem symptoms and
steps to correct the problems.
The "Troubleshooting charts" on page 59 list problem symptoms and steps to
correct the problems.
Real Time Diagnostics tests the major components of the BladeCenter unit,
including the management modules, I/O modules, removable media drives, and
the blade servers, while the operating system is running. Real Time Diagnostics
can be plugged into an existing IBM Director environment or installed without
IBM Director present. For documentation and download information for Real Time
Diagnostics, see
http://www.ibm.com/servers/eserver/xseries/systems_management/xseries_sm.html.
Note: See the Hardware Maintenance Manual and Troubleshooting Guide for
your blade server type for more information.
Use light path diagnostics to identify system errors quickly. See the "Light path
diagnostics" on page 63 for more information.
