2L23 and 2L25 CPS Bay 1 both have DSP low battery dropping them from HV. 2L23-2/8 need filament cards for no filaments (swapped fibers on HPA and readbacks good). 2L15-3 needs a 2.5w amp after checking drive out of RFCM. 2L04-2 HV enable fault cleared with new RFCM and buffer card reseat. Downloads took several attempts to pass before Buffer reseated. 2L19-6 will need a 2.5w amp, have one staged at 2L15-3. 1L02-6 isn't regulating CRFP above 3.5Mv/m, most likely RFCM loop.
