== What we did==
- Replaced a computer for k1fw1 as faster one.
Downtime is from 9:41 to 10:37. - Stopped the all circuits for k1pr3 and k1prm in order to change the DC power supply.
- Stopped k1test0 computer (on which k1grdconfig, and k1detdq is running) in order to remove unnecessary DAC cards.
We entered EXV room from 9:50 to 10:50.
ETMX was already in the safe state for Dr. Okutomi and Yamada-kun's work.
So we never touch the ETMX guardian today.
