I've got an old E250 server where a front error LED is showing. I've read through the Sun docs (Sun Enterprise 250 Server Owner's Guide - Sun Microsystems) but it's only the 'General fault' LED (About the Status and Control Panel (Sun Enterprise 250 Server Owner's Guide) - Sun Microsystems) showing - not one of the specific LEDs.
prtdiag and /var/adm/messages don't show any errors and I can't track down what's causing it.
Anyone have any ideas?
