Introduction

For information about troubleshooting the entire fabric, refer to the Fabric OS Troubleshooting and Diagnostics Guide.

The Brocade DCX 8510-4 includes a number of diagnostic aids to assist with troubleshooting, including LEDs on the hardware, commands that display current status, diagnostic tests for hardware and software, and error messages. In addition, a number of managing and monitoring features are available, such as Fabric Manager, Web Tools, Fabric Watch, and Advanced Performance Monitoring.

If the Brocade DCX 8510-4 does not operate as expected, the following steps can be taken to diagnose the problem:

•Check the LEDs and see the LED tables (Chapter 4, “Monitoring System Components”) for interpretation and recommended actions.

•Review the results of the last POST run by the Brocade DCX 8510-4 (“Interpreting POST and boot results”).

•Review the error logs. (Refer to the Fabric OS Troubleshooting and Diagnostics Guide for more information).

-Review RASlog entries.

-Type the sensorShow command to determine the status of the hardware components.

-Run diagnostic tests (“Diagnostics”).

-Reboot the Brocade DCX 8510-4 or power the entire chassis off and then on (“Powering off the Brocade DCX 8510-4”and “Providing power to the Brocade DCX 8510-4”).

If the problem is still unresolved after these steps, contact your support provider. The information required by your support provider is listed under “Getting technical help.”
