RFM for X-arm is not available now.
All RFM0 connections (X-arm) are now broken by some reason.
I'll enter the mine...

A trouble seems to occur on K1IX1.

There is surely no light on RFM card on LSC (Fig1), ASC for X-arm network, and IX1 (Fig2).
But RFM switch doesn't detect any connection trouble (Fig3).

By unplugging RFM cable of IX1, RFM connection on X-arm is recovered except k1ix1.

Finally it was recovered by unplugging/re-plugging SFP module...

----
What I did
1. check lspci and dmesg => RFM card had been detected by OS and real-time model.
2. restart model => not solved
3. reboot model => not solved
4. replace SFP module for IX0 on the RFM switch as spare one => solved
5. put original SFP module back => works well... (why?)
