Chapter 10. Solving problems
This section provides basic troubleshooting information to help you solve some problems that
might occur while you are setting up the switch module.
If you cannot locate and correct a problem by using the information in this section, see Appendix A,
“Getting help and technical assistance,” on page 43.
Running POST
To ensure that it is fully operational, the switch module processes a series of tests during power-up
or a restart (power-on self-test, or POST). These tests take approximately 1 minute to complete. The
management module reads the test results and displays them for you. During normal operation,
these tests are completed without error, and the green OK LED is lit. However, if the switch module
fails POST, the amber switch module error LED and the system-error LED on the BladeCenter unit
are lit. An event is stored in the event log in the system status panel of the management module.
The specific failure is displayed on the system status I/O module panel of the management
module.
Note: For the locations and descriptions of the switch module LEDs, see , “Chapter 5. Information
panels, LEDs, and external ports” on page 23 .
POST errors
There are two types of errors: noncritical and critical. A noncritical error applies to one port, and the
switch module is operational. You can continue to operate the switch module; however, you must
replace it as soon as possible. When critical errors occur, the switch module does not operate. To
view POST results, complete the following steps:
1. Log on to the management module as described in the IBM BladeCenter Advanced
Management Module Command-Line Interface Reference Guide . If necessary, obtain the IP
address of the management module from your system administrator. The login window opens.
2. Turn off the power to the switch module; then, turn it on again.
3. After POST is completed, the management module displays the results. Refresh the window to
view the POST results. If a critical error occurs, replace the switch module. If a noncritical error
occurs, see the switch module error log for additional details.
Table 7 describes the basic critical and noncritical failures. This abbreviated list is representative; it
is not an exhaustive list. An error code is associated with each failure. Error codes are displayed on
the Management Module Switch Information window. Be sure to note the applicable error code and
corresponding failure. You might have to provide this information when you call for service. For
details, see
“Appendix A. Getting help and technical assistance” on page 45.
