Ok, I got most of the way through the update, at which point the updater said it couldn't see the link station.
The link station was dead, and not accessible from any other machine.
When I turn the LS on, I can hear it try to start up for about 10-15 seconds while the blue LED flashes, then it shuts down. It keeps retrying, keeps shuting down again.
Any ideas? I'm not sure how old these are, at a guess about one year.
