We investigated the network connection.
The investigation will continue.

We have continued to check the network connection from last time.
We will do it again next week.
Please refer to the following for details.
JGW-E2112439
We have changed and worked on the following settings.
- Changed the IP address of the SRM Rack SW from the default (192.168.0.239) to 10.68.97.174.
- Connected the power cable to the Picomotor of ITMX and ITMY to check the stabilization status.
If the cable gets in the way of your work, remove it and put it back after you are work.
The following problems were found
- The IP address of the BS Rack SW is 169.254.100.21, so it cannot be accessed on the DGS network.
The IP address will be changed to 10.68.97.175.
- Communication between 1Gbps SWs (SR2-SRM, N1-BSWS) is actually at 100Mbps.
- There is no port to insert the STM1 Picomotor cable.

Continuing from last week, we have investigated the network connection.
Please refer to the following for details.

In the Center area, we found the following problems
The SW at the root of the computer room was connected to a 100M PoE.
> In the 1Gbps SW connection (SR2-SRM, N1-BSWS), the actual speed was 100Mbps.
I made a mistake in the above statement.
The actual speed is 100Mbps between 1Gbps SWs (N1 and all Ss connected to N1).
I changed the following settings.
The IP address of the SRM Rack SW was changed from the default (192.168.0.239) to 10.68.97.174, but since 174 was being used by an unknown SW, the SRM Rack was changed again to 10.68.97.177.
The BS IP address is now set to 10.68.97.175.
Details are reflected in the KAGRA Wiki.

We have investigated the network connection of both ends.
Please refer to JGWDoc for details.
We also checked the picomotor status of the X and Y-Ends.
In the ping test, there was no response in both ends.
X: Tried to connect to USB, but could not.
Restarted after re-powering. Settings (IPADDR, GATEWAY, NETMASK) are fine.
After re-powering, tried to connect to USB, but still could not connect.
When I returned to Mozumi, I was able to connect to another Picomotor via USB, so it might be a problem with the USB connector on the Picomotor itself.
Y-end had the same problem as X, according to miyo-san's research, but I did not test the USB connector.
I left it connected for now to check the stability.

Checked the VIS network in the center area.

We have investigated the cable length for the new VIS network.
Please see the following document for details.

2021/02/15 Implementation:
We have measured the cable length of the new network in the IXC and IYC areas.
