Solving problems, Running POST, POST errors

Chapter 8. Solving problems

This section provides basic troubleshooting information to help you solve some problems that might occur while you are setting up the GbE switch module. The Nortel 10 Gb Uplink Ethernet Switch Modules for IBM Bladecenter Application Guide provides more details about troubleshooting the GbE switch module.

If you cannot locate and correct the problem using the information in this section, see Chapter 9, “Getting help and technical assistance,” on page 41.

Running POST

To ensure that it is fully operational, the GbE 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 GbE switch module fails POST, the amber error (fault) LED and the system-error LED on the BladeCenter unit is 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 location and description of the GbE switch module LEDs, see “LEDs” on page 6.

POST errors

There are two types of errors: noncritical and critical. Noncritical errors apply to one port, and the GbE switch module is operational. You can continue to operate the GbE switch module; however, if necessary, you must replace it as soon as possible. When critical errors occur, the GbE switch module does not operate. If a critical error occurs, the switch will try complete the startup sequence and initialization process. To view POST results, complete the following steps:

1.Log on to the management module as described in the User’s Guide or the Command Line Interface Reference Guide for your management module. 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 GbE 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 GbE switch module. If a non-critical error occurs, see the GbE switch module error log for additional details.
