In 2012 I was at a data center in Colorado where we were upgrading them from OS/390 2.10 to z/OS 1.13 and simultaneously replacing their 9672 with a z/114. We had just completed the "2 weeks in production" period for the z/114 and was going so well that the site decided to have the 9672 removed early (we were scheduled for 1 month of hot backup). The 9672 still had some old power cables snaked around under the raised flooring and I guess they were stuck around some REALLY old Buss and tag (from their 4381 they had in the late 80's) cables and raised floor stands. We offered to help the guy unwrap them, but he told us that we were not "certified electricians" and that the union would crucify him if he allowed us to touch anything. The electrician then apparently decided that since he had disconnected the power cables from the wall and the CPU that he could just "give them a good yank". We were discussing things with the client in their operations area, when we felt a sort of "vibration" and the consoles locked up. It turned out that the electrician had yanked the floor supports completely from the safety stands and the 9672 fell about 2 feet to the cement.
Luckily it wasn't the new z/114, which was installed only about 20 feet away from the old box. He did however cause our first hardware issue with the z/114 by simultaneously severing the FICON connections to the DASD. The FICON cables ran a few feet away from the 9672, but it was close enough for parts of the floor to land right on them and cut them all but one. Unfortunately that "one" was to a tape control unit. It took us 4 hours to locate and get 11 new FICON cables run. it was a Monday, so it could have been much worse.
