POST
Use this information for more about POST self-test errors for the blade server.
When you turn on the blade server, it performs a series of tests to check the
operation of the blade server components and some optional devices in the blade
server. This series of tests is called the power-on self-test, or POST.
1. If a power-on password is set, you must type the password and press Enter,
2. If POST is completed without detecting any problems, a single beep sounds,
3. If POST detects a problem, more than one beep might sound, or an error

BladeCenter HS12 Type 8014, 8028 or 1916: Problem Determination and Service Guide
Time Diagnostics, see http://www.ibm.com/systems/management/. For more
information about diagnostic programs and error messages, see the Problem
Determination and Service Guide for your blade server.
The IBM Dynamic System Analysis (DSA) diagnostic programs are the primary
method of testing the major components of the blade server. The diagnostic
programs are available in the preboot environment by pressing F2 during the
boot process. The Preboot DSA diagnostic programs are stored in integrated USB
memory and collect and analyze system information to aid in diagnosing blade
server problems. The diagnostic programs collect the following information
about the blade server:
– System configuration
– Network interfaces and settings
– Installed hardware
– Light path diagnostics status
– Vital product data, firmware, and BIOS configuration
– Storage drive health
– Baseboard Management Controller logs
The diagnostic programs create a merged log that includes events from all
collected logs. The information is collected into a file that you can send to the
IBM Support Center. Additionally, you can view the blade server information
locally through a generated text report file. You can also copy the log to
removable media and view the log from a Web browser.
Note: If you are unable to find the system-error logs in the blade server
firmware code, view the system-event log in the BladeCenter management
module.
Use light path diagnostics LEDs on the system board to diagnose system errors.
If the system-error LED on the system LED panel on the front or rear of the
BladeCenter unit is lit, one or more error LEDs on the BladeCenter unit
components also might be lit. These LEDs help identify the cause of the
problem. Blade server error LEDs are described in the Problem Determination and
Service Guide for your blade server.
