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.
