== What we did ==
1. Replacement storage for k1tw1
2. Rebuilding and restarting k1ioptest0 model.
3. Replacement power supply for ETMX circuits
4. Network re-cabling around center area.
== Detail ==
1. Down time was 10:03 - 10:23
Relating with this work, k1nds1 also down from 10:21 - 11:20
During this time, minute, 10min trend, and hour trend on dataviewer is available on only k1nds0.
2. Unnecessary DAC, ADC card on IOP model was removed.
k1grdconfig and k1detdq0 are also restarted.
Finally, burt snapshots at 08:40 today are applied for these models.
3. For replacing a power cable for DC-18V and a new cable for DC-24V is installed.
ETMX was in safe mode and all circuits were turned off during this work.
4. A new network switch was installed around BS workstation area.
Workstation around BS area, Wireless router around IOO area connected to this network switch now.
Don't connect pico driver, stepper driver, or other 100Mbps instruments.
And don't connect instruments which need EPICS network to switches in/on field racks.
We plan to separate instruments which doesn't require EPICS packets from CDS network after O3.
Picomotor wiki was also updated.
