SGI Onyx - Three Phase to Two^H^H^H Single Phase conversion

Greetings all; Further to my queries some weeks ago, and list suggestions (in particular Pat Finnegan), I have the answer regarding running my three-phase configured Onyx on a single-phase 220v outlet. I removed the four-wire TwistLock plug end and replaced it with a three-wire stove outlet plug (NEMA10-50R). I connected L1 and L3 to one hot leg of the 220v plug, and L2 to the other, and N to the GND line. Only two of the OLS' (PSUs) come up in this wiring manner, so I removed the one that did not (without removing it the Onyx notices it is there, but not producing juice, and fails self-test). The System Controller comes up, boot arbitration completes and Thunderbirds Are Go. Actually, one of my blowers has kicked the bucket (and, to be fair, the other is pretty grumpy, but eventually spins up) and the Onyx is halting on a BLOWER B FAILURE. But that's another story :) Thanks again for your help. I thought I'd post back and leave this in the archives for any future Onyx suckers in my position. JP Hindin
