Introduction
For information about troubleshooting the entire fabric, refer to the
Fabric OS Troubleshooting and
Diagnostics Guide.
The PowerConnect B-DCX-4S 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 PowerConnect B-DCX-4S 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, “Monitor System Components”
) for
interpretation and recommended actions.
•
Review the results of the last POST run by the PowerConnect B-DCX-4S (
“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 PowerConnect B-DCX-4S or power the entire chassis off and then on
(
“Powering off the PowerConnect B-DCX-4S”
and
“Powering on the PowerConnect
B-DCX-4S”
).
If the problem is still unresolved after these steps, contact your support provider. The information
required by your support provider is listed under
