5 Troubleshooting

The purpose of this chapter is to provide a preferred methodology (strategies and procedures) and
tools for troubleshooting complex error and fault conditions.

Methodology

General troubleshooting methodology

The system provides several sources of information for troubleshooting:

LED status information

Front door display/insight display
The OA CLI
The OA GUI
LED status information
The LEDs provide initial status and health information. LED information should be verified by the
other sources of status information.
See "Superdome 2 LEDs and components" (page 55)
TIP: The CLI is the most efficient way to verify the information provided from LEDs.

OA access

You can access the Superdome 2 OA by using either a telnet session or a ssh connection. This
can be done by connecting a laptop to the eSwitch using a standard LAN cable using telnet.
IMPORTANT:
the OA should be always be accessed using telnet or ssh.

CLI
