Chapter

Troubleshoot the Switch

This chapter provides these topics for troubleshooting the switch.

Obtain Troubleshooting

Information

The status indicators on the front panel provide troubleshooting information

about the switch. They show power-on self-test (POST) failures,

port-connectivity problems, and overall switch performance. You can also get

statistics from the browser interface, the command-line interface (CLI), or a

Simple Network Management Protocol (SNMP) workstation.

Verify Switch POST Results

As power is applied to the switch, it begins the POST, a series of tests that runs

automatically to ensure that the switch functions properly. It might take several

minutes for the switch to complete POST.

POST starts with status indicator tests that cycle once through the EIP Mod, EIP

Net, Setup, Pwr A, and Pwr B status indicators. While POST proceeds, the EIP

Mod status indicator blinks green, and all the other status indicators remain off.

If POST completes successfully, the System status indicator changes to solid

green, and the other status indicators display their normal operating status. If the

switch fails POST, the System status indicator turns red.
