SG210 HA unlinked and port not blinking

Question

Hello Community, 
 I have two Sophos UTM SG210 working in HA Mode (SG210A and SG210B). 
 We recently connected everything on an Aruba switch. The LAN Port on the Aruba switch for SG210B was configured incorrectly. The VLAN for Management wasn't assigned. 
 At the moment the SG210B is master. So we can't connect to the Aruba Switch in the Management VLAN. The Sophos web interface shows me correctly that SG210A is unlinked. At the same time there are no "blinking" signals on the LAN port of the SG210A and the Aruba port. 
 Is this behavior normal if a Port is unlinked? Does it behave as if the port is not connected at all? 
 I am not quite shure if I can shut down SG210B and everything will be ok as soon as SG210A is master. 
 If the "not blinking port" indicates a Aruba error I will lose LAN completely if SG210A becomes master. But if this is working I can configure the LAN Port of SG210B myself via Aruba web interface (I am not common with the console). 
 Thanks for your help.

Hello Bepo, 
 
 thanks again for your help. Last Night i reboot the Aruba switch and the port of SG210A was alive again. I turned off SG210B an I could access the aruba web interface and corrected the vlan config myself. Now the HA works fine. 
 
 Just for my curiosity I tried to connect via console. On our second aruba switch this works fine and I can run your commands. But if I try the same thing on our main aruba switch (which was part of the problem), I get an "can't find file on com3" error starting putty. I think I need to have an aruba expert check this out. 
 
 So the "not blinking" port was definitely an aruba switch problem and not caused of the "unlinked" state of the firewall.
