Maintenance

6.1.4Link LED

If the Link LED fails to light, the module is not communicating with the Ethernet hub.

Troubleshooting 1. Make sure that the cable has been installed correctly and the module is functioning properly.

2. Verify that the hub is working properly.

6.1.5Kernel LED

If the Ready LED is on and the Kernel LED is flashing, the module has detected an invalid software image. If the Ready LED is on and the Kernel LED is shining steadily, an attempt to download a software image has failed and the module is in kernel mode.

In either case, download a new software image, using the procedure on page 61.

Figure 26 LED Display When the Error Log is Full

The Fault LED will flash briefly following an error as the module attempts to recover. The Fault indicator will remain on only when the error log is full (the error log has space for 1023 entries). In that case, the module will be unable to recover. Use the ERRLOG utility to clear the error log, as described on page 57.
