What is excelSysLastAlarmRefClockSrc?

If the last alarm was a reference-clock-source-lost alarm, this identifies which clock: refClock1(2) or refClock2(3); notApplicable(1) if the last alarm wasn't a clock-loss event. Checked specifically after a timing/synchronization alarm to know which of the switch's two reference clock inputs actually failed.
