Hi guys
we have a Smart-UPS 1000 and yesterday was a happening because the device turned off without any previous sign. The problem was the next:
the device could turn on but it couldn't supply the other devices and it showed, we have to contact with APC immediately or something like this.
I wasn't there so I don't whats happend exactly. Today I tried to turn on and magicly it could turn on without any problem.
I read out the logs and I've found 6 fault code "boost/trim rly".
Please help me what does it mean because I don't find any useful info about it.
The battery was replaced last July.

It means the UPS is seeing an output voltage outside of what it expects to see. The most common cause of that is a relay weld on the boost/trim relay(s).Other hardware failures can cause the same issue.
If it powers up and runs ok and there is a faulty relay, next time you experience a power transient that would normally cause the UPS to boost or trim it'll quite likely happen again and you'll lose your load.
