Cabling for the shaker injection at PSL room
[YokozaWashimi]

For the future shaker injection test at PSL room, we performed the cabling from the MCF0 rack to cable entrance at the PSL room.
We used the DAC0 9 - 12 ch.

We don't know this work affect or not, I found the model of the K1MCF0 was not working, as shown in Fig.1.

I restarted all models on k1mcf0, because models downed around 2:40am on Feb. 8th due to probably timing glitches.
The Front-end computer was alive at this time.
