V7 control RRC against V1 radio RRC

[ea3in]

Hello

My working setup is TS-480 together with a V1 RRC pair. It works perfect

Now, I have purchased a new V7 RRC to be used as the control unit (with the 480 head). I doesn't establish the connection when pressing the button at the Ts-480 head.
All firmware are the same (2.90)
I have exporte and imported the settings in order to be sure that the config is exactly the same

This RRC mix should work. Right?

Any idea?

Ignore it

A matter of jumpers

Not jumper related

It is caused by the ARP table of the etehrnet switch when changing the RRCs
If I reset it, everything is ok
