Chapter 5. Solving Problems

This section provides basic troubleshooting information to help you solve some

problems that might occur while you are setting up the switch. The

Application

Guide

for the switch provides more details about troubleshooting the switch.

If you cannot locate and correct a problem by using the information in this section,

see

“Getting Help and Technical Assistance” on page 49

Running POST

To ensure that it is fully operational, the switch processes a series of tests during

power-up or a restart (Power-On Self-Test, or POST). These tests may take up to

two minutes to complete. The Lenovo Flex System 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 switch Power LED is lit.

However, if the switch fails POST, the yellow 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 module panel of the CMM.

Note:

For the locations and descriptions of the switch LEDs, see

“Locating the

Information Panels, LEDs, and External Ports” on page 28

POST Errors

There are two types of errors: 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 on to the CMM Command-Line Interface (CLI) as described in the CMM

documentation. If necessary, obtain the Internet Protocol (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.
