In the interests of tacit communication of scientific knowledge, I here reveal a nugget of knowledge which may or may not prove useful to new LIGOites: sometimes when front-end machines are rebooted, the hardware they control can wind up in a state which is not accurately represented by the EPICS values you may see. This can be easily rectified by momentarily changing the EPICS settings in question. For reference, this came up tonight in the context of the whitening gain sliders for the TransMon QPDs.
