Chapter 7. Solving problems
Use these instructions to resolve any problems you may encounter while installing the blade
server.
If you install the blade server in the Blade Chassis and the blade server does not start,
perform the following actions:
•
Make sure that the Blade Chassis is correctly connected to a power source.
• Reseat the blade server in the Blade Chassis (see Installing the blade server in a Blade
Chassis on page 62 ).
•
If the power-on LED is flashing slowly, turn on the blade server (see Turning on the
blade server on page 15 ).
• If you have just added a new optional device or component, make sure that it is
correctly installed and compatible with the blade server and its components. If the
device or component is not compatible, remove it from the blade server, reinstall the
blade server in the Blade Chassis, and then restart the blade server.
If the blade server does not start after you have performed the preceding actions, see the
Problem Determination and Service Guide for your blade server on the Resource DVD .
7.1 Diagnostic tools overview
The following tools are available to help you diagnose and solve hardware-related
problems:
• POST codes, error messages, and error logs
The POST error codes indicate the detection of a problem. See the Problem
Determination and Service Guide for more information.
•
Troubleshooting tables
The troubleshooting tables list problem symptoms and actions to correct the problems.
See the Problem Determination and Service Guide for your blade server.
• Light path diagnostics
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 Blade Chassis is
lit, one or more error LEDs on the Blade Chassis 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.
•
Dynamic System Analysis (DSA) Installable and Portable Edition diagnostic program
DSA tests the major components of the Blade Chassis, including the management
modules, I/O modules, removable-media drives, and the blade servers, while the
operating system is running. For more information about diagnostic programs and
error messages, see the Problem Determination and Service Guide .
Note If you are unable to find the system-error logs in the blade server firmware
code, view the system-event log in the Blade Chassis management module.
