Sun was the last SPARC server running in Tardis, time of death 2014-11-14T17:46, age 10 years (DoB tbc)
PSU was replaced with the one from Mars on 2014-03-10, warning now gone. -
Currently Sun is displaying a warning light on th front bezel & rear PSU. Probably it's a PSU fan failure, so at some time this should get swapped out with another from one of the other Sun machines.
