This is last Friday's work.

This is a continuation of K-Log#20547.

Work contents

1. C1 network SW was replaced with another SW (M100-26G V2H2).
　Then, LAN connection was restored to the state where the error (0x4000) occurred.

 Check result :
  There was no improvement in DAQ error (0x4000).

2. Connected all RTPCs (C1, C2, C3) directly to the SW of NETGEAR to which k1dc0 is connected.

 Confirmation Result :
  There was no improvement of DAQ error (0x4000).
