Generating a File for Technical Support

In order for technical support to be most effective, the user should provide them with the information contained in the system logs. Use the logger get support-filecommand to generate a support file for the use of Cisco technical support staff.

To generate a log file for technical support:

From the SCE 2000# prompt, type logger get support-filefilename and press Enter.

The support information file is created using the specified filename, and the SCE 2000# prompt appears. This operation may take some time.

Check the LEDs

The front panel LEDS are the most immediate problem-detection mechanism of the platform. Refer to the following sections for information on SCE 2000 platform LEDS:

•Front Panel

•LEDs

•SCE 2000 Operational Status (on page 8-7)

SCE 2000 Operational Status

The following table lists the operational states of the SCE 2000. The Status LED on the SCE 2000 Front Panel reflects the current SCE 2000 operational status. The operational status can be displayed using CLI command show system operation-status.
