[Ikeda, YamaT]

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.
