h1sush2a, h1sus2b SUS taken to SAFE; SEI HAM1 and HAM2 brought to ISI_DAMPED_HEPI_OFFLINE -- merge of sush2a and sush2b systems into sush12 system begins!
J. Kissel After offloading the IMC WFS (LHO:88510), and saving alignment offsets in respective safe.snaps (LHO:88511 and LHO:88512), I've brought all SUS on the h1sush2a and hsush2b computers to SAFE (that's MC1, MC3, PRM, PR3 and IM1, IM2, IM3, IM4, RM1, RM2, PM1, respectively). I've also brought the HAM1 and HAM2 SEI systems to ISI_DAMPED_HEPI_OFFLINE. This is all in prep for the h1sush2a and h1sush2b merge into h1sush12, which is coincident with the DACs in these chassis getting upgraded to 32 CH 28-bit DACs per ECRs E2400409 and E2500296 scheduled via WP 12901.
