Hi, I have a Power 10 with a stand-alone IBM i 7.4 partition. with lan console, The console card is an EN2W PCIe3 4-port 10GbE BaseT RJ45 Adapter.

When I restart the PC I use for the console or when I end the console session, it no longer connects. I just perform an IPL on the power supply and it works again. I've already updated the ACS and changed the cable to UTP CAT 7 with the same result. What could be happening?

Dear Miguel

Did you use instruction provided in this web page: IBM Power10 Cabling the server and accessing Operations Console at https://www.ibm.com/docs/en/power10?topic=use-cabling-server-accessing-operations-console.        

Also this one: Basic Console Config for LAN Console on Existing System at https://www.ibm.com/support/pages/basic-console-config-lan-console-existing-system.       

ACS Console Setup and Installation Using Default IP Address at https://www.ibm.com/support/pages/acs-console-setup-and-installation-using-default-ip-address.     

Miguel,

I ran into something similar on a new Power10 with the 10 GB cards. Varying on a line description would put the status to failed. I also had to keep IPL'ing to get the console to connect.

Look to see that you have the PTF's identified in the following link on your system:

Hello,

 I assume the P10 10GBe card is directly connected to the PC LAN card (1GB ?). If my assumption is correct, did you try to use a 1GB switch to connect both P10 and PC through it and see if it makes any difference ?

Regards,

Nikos

Hi Miguel,

What does it look like when you go into your SST -> Work with Service Tools Server Security and Devices -> F5? If you try and pull up the console on a different work station, are you able to do a takeover? Are there any codes listed when you pull up the Virtual Control Panel for the LAN in ACS? My experience is almost exclusively with using an HMC, but it sounds a lot like the console session is hanging rather than disconnecting. If console takeover isn't enabled and the session is still active to the OS, it would only reconnect with an IPL.
