Brilliant. Reminded me of our machineroom where we planned to deploy a cray-1 to use the space vacated by an IBM 3300 (The cray was a freebie from Boeing, a mandatory investment in R&D offsetting a huge defence contract)<p>Unbeknownst to us, the building wasn't adequately earthed and we had a 48v ground potential across data frames either end of the building which must have existed day #1 from the 1960s, but with limited cabling and inter machineroom comms never been noticed. Amongst other remediation we had to bury a huge ground plane spike in the garden and tie the all the raised floor tiles into a functional groundplane with wire to fix things.
