NE and WE RHs switch OFF for NEB UPS replacement

As agreed, to proceed with the NEB UPS replacement, the NE RH were switched OFF at 08:32 UTC.

At approximately the same time (08:33 UTC), the WE RH were also switched OFF.

At 08:34 UTC, Maria physically switched OFF the power supply of the NE RH to avoid any potential damage due to the current shutdown.
