New equipments for ITM front-end
A V4 front-end computer and a new IO chassis (S2416127) for replacing ITM equipments were brought to the server room in the mine.
To let it dry out, I haven't powered it on today.

Though there were several rack mount rails, there was no computer-side bracket.
It must be also brought from SK computer room when they will be installed and launched up.

New equipments will be launched up as a test branch named 'itmz' at first

We launched up a new V4 computer as K1IZ1.
Now both V4 front-end and a new IO chassis are in the server room to check the stability with short cable connection.
And also, K1IZ1 runs only with PXE/NFS connection to k1boot and without DAQ/RFM connection to another CDS nodes to separate from existing control system.
After checking the stability by short cable connection during next few weeks, a new IO chassis will be moved to IXV or IYV area to check a stability with long (~100-150m) cable connection.
After starting SRM work in March, K1IZ1 will be connected to DAQ/RFM and finally it will be replaced as current ITMX or ITMY until the end of March.

For launching K1IZ1, node information was added to dhcp@k1boot and dns@k1gate.

[YamaT-san, Ikeda]

We created and executed the K1IZ1 model file.
The model was based on K1IX1 and modified to K1IZ1.
All RFM-related components were removed and changed to either terminate or connect to GND.

Not yet registered with the DAQ.
On the maintenance day, add all models to rtsystab and register only the Testpoint for k1iopiz1 with the master.

The following numbers were assigned for DCUID:
58: k1iopiz1
62: k1visitmzt
67: k1visitmzp
77: k1visitmzlsc
118:k1sendbeaconiz
