During diagnostic procedures following UPS failure of 3/6, the affected UPS failed again. This caused a number of single-source power supply serversDuring diagnostic procedures following UPS failure of 3/6, the affected UPS failed again. This caused a number of single-source power supply servers to crash, most noteably the SIS running on the IBM iSeries (Jenzabar TEAMS 2000), the EMU web server (www.emu.edu) and the Oracle Calendar server.

To prevent this from reoccurring the following servers were moved to the north rack MATRIX UPS: IBM I-series, TS, and Tserve. ZW is still connected to the additional small 280 UPS. All test servers located on the north rack have been powered off – to increase run-time/decrease load on the MATRIX.

The control head has been determined to possibly be the cause due to other issues currently present. A new one is being shipped. We will need to test to see why, when removing the control head, power was lost. We will need to document when this occured – when placed in bypass, when removed, when replaced, etc.

A couple of issues were also discovered in the configuration of the powerchute agent on ZW. This is due to it being a fresh install – use the web client to modify the parameters.
