We'll aim to do this between 10AM and 2PM Tuesday 6/2. All PSS segments will be in Restricted Access beginning at 10AM. No sweeps until after the PSS-stamp affected portions of these reboots are complete. Adding to SAM Cal.

Thanks for the reply. So Tuesday 6/2 is the right time, with Inj -> BSY in Restricted Access, for the UPS battery swap. Updating SAM Cal with as much.

UPS affects NL I/O monitoring Inline Dump and Chicane Magnets. Theoretically you can swap batteries without loosing power to protected equipment but to be on the safe side I would suggest to do it when NL is open.

All three items sound good.
1) Can do this without taking down items powered through UPS? What is powered through the UPS, if they have to be powered down for the battery swap? This would inform timing.
2) Tuesday 6/2 would be the day for this with the SL in Restricted Access.
3) Hall B will be in Restricted Access starting Mon 6/1 until at least Fr 6/12. I would advise aiming for the second week for this.

Area we need to go in is currently ODH2 due to a failed exhaust fan. Going to post-pone until the fan is repaired and the area dropped to ODH1.
