Introduction
For information about troubleshooting the entire fabric, refer to the Fabric OS Troubleshooting and
Diagnostics Guide.
The Brocade DCX 8510-8 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 8510-8 does not operate as expected, the following steps can be taken to diagnose
the problem:
• Check the LEDs and refer to the LED tables (Monitoring System Components on page 47) for
interpretation and recommended actions.
• Review the results of the last POST run by the Brocade DCX 8510-8 (Interpreting POST and boot
results on page 146).
• Review the error logs. (Refer to the Fabric OS Troubleshooting and Diagnostics Guide for more
information).
‐ Review RASlog entries.
‐ Use the sensorShow command to determine the status of the hardware components.
‐ Run diagnostic tests (Diagnostics on page 147).
‐ Reboot the Brocade DCX 8510-8 or power the entire chassis off and then on (Powering off
the Brocade DCX 8510-8 on page 46 and Providing power to the Brocade DCX 8510-8
Backbone on page 27).
If the problem is still unresolved after these steps, contact your support provider.
Obtaining chassis and component status
The CLI commands in the following table provide status and environmental information about the
chassis and its components. These commands provide information only, and they do not interrupt traffic
flow. For more information about these commands, refer to the Fabric OS Command Reference.
