Link 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.

6.1.5

Kernel 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.

6.1.6

Fault LED

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.
