Default Unexpected power failure during run

Hey NextSeq500 users, has anyone experienced an unexpected power failure during their run? Have you determined any causes? A instrument power failure occurred 10 hours into my last run.

As in the sequencer just died while the power was still on in building? Do you not use UPS's on your sequencers to filter out power anomalies?

The power failure was not a result of a utility failure. Yes, the instrument was connected to a UPS. It appears to be an instrument power failure.

I assume you have eliminated a faulty UPS as a possible cause? If your sequencer is under a maintenance contract you should contact Illumina tech support ASAP.

Never seen a sequencer just die (out of 20 over years) so something is not right.

Default Update: NextSeq500 Power Failure

The power failure turned out to be a failure of one the computer fans in the instrument. After 10 hours into the run when the computer started heating up with the processing of data, the processing unit overheated and shutdown.
