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 Gigabit Ethernet
switch module. The Cisco Intelligent Gigabit Ethernet Switch Modules Software
Configuration Guide provides more details about troubleshooting the Gigabit
Ethernet switch module.
If you cannot locate and correct the problem using the information in this
section, see Chapter 7, "Getting help and technical assistance," on page 37.
Running POST
To ensure that it is fully operational, the Gigabit Ethernet 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 Gigabit Ethernet switch module fail POST, the amber Gigabit
Ethernet switch-module 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 Gigabit Ethernet switch module
LEDs, see "LEDs" on page 11.
POST errors
There are two types of errors: noncritical and critical. Noncritical errors apply
to one port, and the Gigabit Ethernet switch module is operational. You can
continue to operate the Gigabit Ethernet switch module; however, you must
replace it as soon as possible. When critical errors occur, the Gigabit Ethernet
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 BladeCenter
Management Module User's Guide. If necessary, obtain the IP address of the
management module from your system administrator. The login window
opens.
2. Turn off the Gigabit Ethernet switch module; then, on again.
