Solving Problems
This chapter provides troubleshooting information to help you solve problems that might occur
while you are setting up the IBM Flex System EN4023 10Gb Scalable Switch.
If you cannot locate and correct a problem by using the information in this section, see
Appendix A"Getting Help and Technical
Running POST
The switch processes a series of power-on self-tests (POSTs) during power-up or a restart to ensure
that it is fully operational. These tests take approximately one minute to complete. The IBM Chassis
Management Module (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
and external ports"
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
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

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
