Working with CSMT. Drive #6 was pulled and replaced. The arry is rebuilding now. Once this process has completed; CMST should give more guidance about what steps to take next. ___end___ KCOR COMMENT BY berkey: Fri Mar 11 02:25:22 GMT 2022 Inspecting the spare MC4u it was concluded the two units had the same gross configuration; with the same boards. On the bench downstairs SPiiPlus NT Suite was used to configure the spare to have identical programs, and variables. The only obvious difference between the two configs was the spare had a different IP address. Once it was confirm the two units had identical configs. The spare was taken upstairs. The NEMA box upstairs was powered down and the cables in the original MC4u were label and removed from the unit. The cables where then switched over to the spare unit. On powered up up the NEMA box there was a distinct smell of burning electronics. At which point the NEMA box was powered back off again. Sniffing over the kcor electronics it seemed that the burning smell was coming from the spare MC4u. Cables were removed from the spare MC4u; and reinstalled into the original MC4u. With the spare unit taken downstairs it became more obvious that the burning was in the spare unit not the rest of the NEMA box. Cables were reconnected to the original MC4u. And the NEMA box was powered back up. And the stages controlled by the MC4u, cover, diffuser, polarizer, polarizer rotation, and O1 focus, were all tested multiple times. Based on the testing it seems normal functionality has been restored. On inspection of the spare MC4u, pulling off the front and back covers no obvious burn scars have been seen. But based on smell it seem like the burning must have come from the 28V powersuply insert. At this point it isn't obvious what the next steps are, but it appears we dont have a ready to go spare MC4u if the origonal one fails. ___end___ GENERAL COMMENT BY berkey: Fri Mar 11 02:32:39 GMT 2022 Nice morning, but heavy clouds after about 11am ___end___ ONSITE STAFF: berkey
