Chapter 4. Solving Problems
This chapter provides troubleshooting information to help you solve problems that might occur
while you are setting up the IBM Flex System FC5022 16Gb SAN Scalable Switch.
If you cannot locate and correct a problem by using the information in this section, see

Appendix A“Getting Help and Technical Assistance” .
Running POST
The switch processes a series of tests during power-up or a restart (power-on self-test, or POST) to
ensure that it is fully operational. These tests take approximately one minute to complete. The
CMM 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 fails POST, the amber
error LED on the switch and the system-error LED on the chassis are lit. An event is stored in the
event log in the system status panel of the CMM. The specific failure is displayed on the system
status I/O panel of the CMM.
For the locations and descriptions of the switch LEDs, see “Locating the information panel, LEDs,
and external ports” on page 22.
POST errors
Two types of errors can result: noncritical and critical. A noncritical error applies to one port, and
the switch is operational. You can continue to operate the switch; however, you must replace it as
soon as possible. When critical errors occur, the switch does not operate. To view POST results,
complete the following steps:
1. Log in to the CMM as described in the IBM Flex System Chassis Management Module
Command-Line Interface Reference Guide . If necessary, obtain the IP address of the CMM
from your system administrator. The login window opens.
2. Turn off the power to the switch; then, turn it on again.
3. After POST is completed, the CMM displays the results. Refresh the window to view the POST
results. If a critical error occurs, replace the switch. If a noncritical error occurs, see the switch
error log for additional details.
Table 12 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 CMM 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
