[Sbs_gems] [EXTERNAL] Question for J0 top

[Holly Szumila-Vance]

Hi,

I think we should keep J0 top on since it ramped down due to an intentional power cycle at the crate. 

We should monitor closely the current though.

We think this is correlated to a power cycle of the VME crate that the HV supply lives in. This would be a precautionary measure, to try and figure out what caused the problems with J0 bot and mid.
