Re: AS/400 UPS
...and the genset that was supposed to start up while the UPS was holding the system up
Or, like one incident, started up happily but died after 10 minutes when the small tank of fuel was exhaused. I was supposed to be kept topped up from the much, much bigger tank under the carpark but that had developed a leak and all the fuel had drained away and no-one had noticed because the fuel level in that tank wasn't monitored..
It was afterwards.
